I. Course Description

The water meter is the last checkpoint in the water distribution

system beore treated water is used by consumers. The water me-

ter is the device the utility uses to measure customer water usage

and determine the amount o the customers bill. This course will

review the various meters, their installation and maintenance,

and causes or water loss within the distribution system.

II. Purpose and Benefts o Water Meters

Purpose o a Water Meter

The purpose o a water meter is to accurately measure the amount

o water that fows through it. This gives the water operator in-

ormation on how much water is produced, treated, and delivered

to customers. One main purpose o a water meter is to determine

how much water customers are using so that they can be billed

properly. In essence, the water meter is a cash register or the

water utility.

Benefts o Metering Water

To the operator, it is benecial to know how much water is being

produced, treated, and delivered. Some benets o metering water

are listed below:

Revenue Determination. The water meter accounts or

the quantity o water used. The cost o water service is more

than the cost o the raw water. The service cost includes

obtaining the raw water, treating it, assuring its disinec-tion, delivering the water, and maintaining the system that

continually provides the water.

Water conservation. Because the customers water bill

is based on the volume o water used, the customer tends

to conserve water.

Leak detection. Leak detection aids the customer in

avoiding catastrophic water bills or helps to explain them.

Determination o unaccounted-or water. Unaccount-

ed-or water is the dierence between the volume o water

pumped into the distribution system and the volume o

water metered rom it.

Accurate blending o water rom dierent sources.

Some cities blend groundwater with surace water, water

rom dierent wells, or water rom dierent surace sourc-

es. Water meters help ensure the water is blended accurately

so that potential water quality problems do not occur.

Determination o uture need. A rise in water consump-

tion may indicate a need to expand the water supply.

III. Meter Designs

There are several types o water meters. They vary in size, and

their design refects the purpose that they serve. Several common

types o meter designs are outlined below.

Positive Displacement Meter

The positive displacement meter is the most common design used

in domestic service. An oscillating (swinging) piston (Figure 1) or

a nutating (nodding) disk, inside the water measuring chamber,

operates the register.

Figure 1: Oscillating piston meter (Courtesy of Sensus Metering

Systems)

Positive displacement meters have magnetically-driven

registers, as do most meter designs. As the measuring

chamber lls and empties with water (positive displace-ment), the piston or disk rotates a magnet that drives the

register. The magnetic drive allows the register to be sealed

rom the measuring chamber, protecting the register rom

moisture, sand, or minerals.

The action o a nutating disk design is illustrated in

Figure 2. Water fowing through the measuring chamber

(A) causes a disc (B) to nutate, which rotates a spindle

(C) and drives a magnet (D). Rotation transmits through

the meter wall to a second magnet (E) that operates the

register.

Figure 2: Nutating disk meter (Courtesy of Badger Meter, Inc.)

The positive displacement meter is accurate over a

broad range o fow rates, but at high fow, the piston or

disk wears rapidly. Excessive piston or disk wear allows

more water to pass through the meter than is registered,

causing the meter to under-register. Like all meters, sand or

mineral deposits can stop the meter.

Current/Velocity Meter

The current or velocity meter operates by water fowing through

a bladed wheel or propeller, which turns a magnet that drives the

sealed register. As the velocity o the water increases, the wheel or

propeller speed increases.

There are three types o current meter: the turbine,

propeller, and multi-jet.

Turbine Meter

In turbine meters, water fowing through a turbine meters fow

way turns a bladed wheel (turbine), which drives the register (Fig-

ure 3 and Figure 4). The turbines rotation is proportional to the

fow rate. Turbine meters are accurate at variable, intermediate,

and high fow, but not low fow.

Turbine meters need straightening vanes inside the

meter body to reduce the eect o water swirl against the

turbine blades. Water swirl increases the chance or inac-

curate registration.

Figure 3: Turbine meter with straightening vanes

Figure 4: Turbine meter (Courtesy of Neptune Meter)

Propeller Meter

In propeller meters, water fowing through the meters fow way

turns a propeller, which drives the register. Like the turbine meter,

the propellers spin is proportional to the fow rate.

The propeller meter is designed or sustained high fow:

ull-on or ull-o, and is used in main lines at surace water

treatment plants or water wells.

Multi-Jet Meter

Water enters a multi-jet measuring chamber through

many openings, and exits through several openings at a

dierent level (Figure 5).

Figure 5: Multi-jet meter (Courtesy of Hendy Performance Meters)

The multi-jet meter is accurate over a broad range o

fow rates and can pass sand or other oreign matter better

than the positive displacement meter. However, mineralbuild-up can cause the meter to over-register to a greater

degree than the positive displacement meter.

Compound Meter

A compound meter consists o two meters in one body: a positive

displacement meter or low fow, and a turbine meter or interme-

diate and high fow (Figure 6). When the fow exceeds the capacity

o the positive displacement meter, a valve opens and directs the

fow to the current meter (Figure 7 and Figure 8). Compound

meters are used at apartment complexes, hotels, schools with

swimming pools, and other wide-range applications.

Figure 6: Double register compound meter (Courtesy of Neptune Meter)

Systems)

Figure 8: Compound meter high ow path (Courtesy of Sensus Meter-

ing Systems)

Fire Service Meter

Fire service meters are turbine or proportional meters (Figure

9). Proportional meters measure a small portion o the fow. The

rest o the fow is un-metered, but is calculated by a multiplying

actor in the register. Because only a small portion o the fow is

metered, this design has very low head loss, which is important

or re ghting.

Neptune Meter)

5/14www.WaterWorldCE.com 5 2011. Texas Engineering Extension Service. All Rights Reserved.

A proportional meter is not accurate at low or interme-

diate fow, and its accuracy at high fow depends on proper

installation.

A re line turbine meter assembly may include a strainer

body to control water swirl into the turbine meter. The as-

sembly may include a low fow domestic supply meter and a

detector check valve to regulate meter operation, depend-

ing on fow demand.

Venturi Meter

The Venturi meter looks like an hourglass, lying horizontally. It

has a converging section, a constricted throat, and a diverging

section. As water passes through the throat, the water veloc-

ity increases, and the water pressure decreases (Figure 10). The

dierence between the low water pressure at the throat and the

higher water pressure downstream is used by a data processor to

calculate the fow velocity, and then the fow rate.

Figure 10: Venturi meter

Venturi meters are used only in pipes that are under

pressure, fowing ull. In the distribution system, they may

be used to meter very high industrial consumption. Also,

they are used or pump testing and measuring raw water

fow into surace water treatment plants.

Pitot Tube Meter

The basic pitot tube meter is a tube with a short, right-angled bend

that is used to measure water velocity (Figure 11). It is usually placed

vertically in moving water, with its opening against the current, and

its upper portion above the water surace. It can measure the fow

rate in a pipe or discharge rom a re hydrant nozzle.

Figure 11: Pitot tube

To measure the fow rate in a pipe, the pitot tube can

be inserted through a corporation stop (Figure 12). A pitot

tube, used in this way, may consist o two tubes: one acing

into the fow, and one acing opposite the fow. The fow rate

is determined rom the water velocity, calculated rom the

two readings.

Figure 12: Pitot tubes inserted into corporation stop

False readings may occur i air bubbles are present in

the hoses that connect the pitot tubes.

Rotometer

Rotometers have a foat, available in various designs, that is lited

in a transparent tube as solutions or gases pass by. The solutions

or gases lit the foat in proportion to their fow rate, which is mea-

sured against the background o the tubes calibration.

In the distribution system, rotometers are predomi-

nantly ound in chlorinators that measure the gas eed rates

(Figure 13).

Figure 13: Rotometer

Electromagnetic Meter

An electromagnetic meter, commonly called a mag meter, creates

a magnetic eld perpendicular to the fow through a section o

straight pipe. As water moves through the magnetic eld, an elec-

trical voltage is produced that is directly proportional to the water

velocity. The meter measures the magnitude o the voltage and

then calculates the fow rate and volume o the fuid (Figure 14).

Figure 14: Electromagnetic meter theory. Voltage produced across

electrodes.

The mag meter is generally not aected by water tem-

perature, viscosity, or turbulence, but the fuid must be

conductive to operate. The largest market or mag meters

are wastewater processing plants, but mag meters are used

in a wide variety o fuid applications in other industries

(Figure 15).

Figure 15: Electromagnetic meters (Courtesy of Badger Meters, Inc.)

Acoustic Meter

Acoustic meters use sound waves to measure open channel or pipe

fow. The sound waves are sent and received through the use o

sensors (transducers) that are attached to the pipe (Figure 16).There are two types o acoustic meters: transmissive and

Doppler. Transmissive designs use sound wave pressure,

and Doppler designs use sound wave requency. The sound

waves may be sonic (audible range) or ultrasonic (inaudible

range).

Figure 16: Acoustic meter sound waves

To measure fow in a pipe, acoustic meters send sound

waves, moving with the fow (rom A to A1) and against it

(rom B to B1). A data processor compares the change in

sound waves rom one direction with the other, calculates

the water velocity, and then calculates the fow rate.

Acoustic meters use less power than magnetic meters,

but acoustic transparency through the pipe material is im-

portant. Thereore, they are more accurate when used with

metal pipe.

IV. Sizing Customer Meters

Meter Specifcations

Dierent meter designs have dierent capacities and ranges o ac-

curacy. Sizing meters appropriately to record a customers range

o fow will help avoid excessive wear. Under-sizing meters causes

pressure loss problems and inaccurate readings o high fow.

Over-sizing meters causes lost revenue due to inaccurate readingso low fow.

I a customers fow requirement is usually below 30

gpm, but has a brie spike o 100 gpm once a week, size the

meter to collect 99% o the 30 gpm fow, i head loss during

the spike is acceptable.

A larger meter that records 99% o the spike may lose a

signicant percentage o the lower fow.

On the other hand, meters rated or a maximum peak

fow rate o 20 gpm on services with a maximum peak fow

rate o 40 gpm can experience magnetic separation and

record only a raction o the total. Magnetic separation oc-curs when the magnet in the meters measuring chamber

has excessive spin and loses synchronism with the register.

This occurrence is likely when a residence is lling a swim-

ming pool or using the sprinkler system.

Flow Range Determines the Meter

The required fow range and peak demand determines the use o

positive displacement, turbine, or compound meters.

Positive displacement meters accurately register low

fows, but prematurely wear under sustained high fow.

Turbine meters are suitable or sustained high fow, but

are not accurate at lower fow unless the turbine meter is

a multi-jet design. Compound meters are a combination o

positive displacement and turbine meter. They accurately

record the largest range o fow rates; however, they have

higher maintenance requirements.

V. Meter Installation

Meters or domestic use are usually set in a meter box near or on

the customers property line. Large meters, or commercial use,

may be set in a meter pit or vault (Figure 17).

Figure 17: Domestic meter set in a meter box and on a riser.

Requirements

Meters must be protected rom reezing. Outside meter vaults

should be excavated below the rost line. Meter manuacturers

make meter housings with a bottom plate or holding bolts that

break in reezing weather to protect the measuring chamber or

register rom damage. The plates or bolts are inexpensive.

Requirements o an acceptable meter installation in-

clude the ollowing:

Watertight connections

A quality upstream shut-o valve with low pressure

loss

Meter set in a horizontal plane or best perormance

Easy access or reading and maintenance

Protection rom reezing

Not a hazard to the public

Meter Bypasses

Customers requiring large meters and uninterrupted service such

as hospitals, schools, or actories should have bypasses around the

meter to allow meter testing or repair without service interruption.

The bypass valve should be locked and inspected periodically.

VI. Replacing Meters

Meter Lie

Meter lie is infuenced by usage and water quality. Minerals and

sand shorten a meters service lie. Generally, it is cheaper to re-

place small meters than to repair them. Repairing large meters,

especially compounds, is usually cost eective.

Meter Testing

Meters may be eld tested with portable test kits, available rom

meter manuacturers or tested in a meter shop. When a customer

indicates that they do not believe that their meter is being read

correctly, it is possible to test their theory by lling a ve gallon

bucket or certied volumetric container with a certain amount o

water through the customers meter. Then, compare the actual

fow o water to what registers on the meter.

I conducting a system-wide testing program, it is best

to test the oldest meters with the most usage, rst, and bud-

get a certain amount to repair or replace them.

Meter Accuracy

Meter accuracy is expressed in percentage and designated as ast

or slow. For example, a meter registering

95 gallons, when 100 gallons pass through it, is 5%

slow. I a meter registers 102 gallons, when 100 gallons pass

through, it is 2% ast.

The American Water Works Association (AWWA)

has accuracy standards or cold water meters. Consult the

AWWAs manual M6, Water MetersSelection, Installa-

tion, Testing, and Maintenance (1999). The AWWA speci-

cations require that a new 5/8-inch by 3/4-inch meter (the

most common meter size used or domestic service) register

at least 95%, and no more than 101% on the minimum fow

rate o 1/4 gpm, and it must register 98.5% to 101.5% on the

normal fow rates o 1 to 20 gpm.

Meter Warranties

Meter warranties are important. I a manuacturer provides a

warranty, it is a good indication that the meter is reliable. Hav-

ing a warranty on a smaller meter provides peace o mind or the

operator; knowing that he/she does not have to worry about the

meter ailing prematurely. Warranties are especially important

on larger meters because o the high cost associated with their

purchase and replacement. When purchasing a new meter, it is

important to ask the manuacturers representative what the war-

ranty covers and what conditions nulliy the warranty.

VII. Meter Records

Uses

Meter records help determine the meter design that is best suitedto local conditions and the most economical length o time to keep

a meter in service. Also, meter records keep track o meter depre-

ciation and the eect o local water conditions on their operation.

Record Inormation

Good meter shop records should indicate the ollowing:

Date o purchase and location

Make, size, and serial number

Test records

Replacement parts used, i repaired

Comments on the meters condition

VIII. Unaccounted-For Water Loss

Acceptable Loss

A well-operated distribution system should have only 10% or less

unaccounted-or water loss. When water loss exceeds 15%, meter

testing, meter replacement, and leak detection programs should

begin (Figure 18).

Figure 18: Meter register with sweep hand and leak indicator(Courtesy of Badger Meter, Inc.)

Causes

Meters are designed to measure the amount o water fowing

through them. When comparisons are made between the amount

o water produced and the amount o water billed, there is always

a discrepancy between the two values. This dierence is called

unaccounted-or water loss.

Some causes o unaccounted-or water loss include the

ollowing:

Stopped or under-registering meters

Undetected leaks

Thet o service

Unrecorded use during re department drills and re

ghting

Fire hydrant fushing

Street washing

Unmetered construction

Unmetered city acilities

IX. Automatic Meter Reading Systems

Description

Besides the visual/manual method o reading water meters, me-

8/2/2019 Metering and Flow Monitoring

ters can be read by touching the register with a handheld wand,

through telephone lines, or by radio.

An automatic meter reading system, or AMR (Figure

19), is the technology o automatically collecting data

rom water meters and transerring that data to a central

database or billing and/or analysis. This means that bill-

ing can be based on actual consumption, rather than on

an estimate derived rom previous consumption. This givescustomers better control over the cost o their water bil l.

Figure 19: Elements of a radio AMR system (Courtesy of Badger Meter,

Inc.)

Originally, AMR devices only collected meter read-

ings electronically and matched them with accounts. As

technology has advanced, additional data can now be

captured, stored, and transmitted to the main computer.

This can include event alarms such as tamper, leak detec-

tion, low battery, or reverse fow. Many AMR devices can

also perorm data logging. The logged data can be used to

collect time o use data, which can then be used or water

use proling, time o use billing, demand orecasting, rate

o fow recording, leak detection, fow monitoring, or other.

AMR technologies include handheld, mobile and net-

work technologies, based on telephony platorms (wired

and wireless) or radio requency (RF) (Figure 20).

Figure 20: Radio AMR system (Courtesy of Sensus Metering Systems)

Touch-Based

With touch-based AMR (Figure 21), a meter reader carries a

handheld computer or data collection device with a wand or

probe. The device automatically collects the readings rom a me-

ter by touching or placing the read probe in close proximity to a

reading coil enclosed in the touchpad. When a button is pressed,

the probe sends an interrogate signal to the touch module and col-

lects the meter reading. The sotware in the device matches the

serial number to one in the route database, and saves the meter

reading or later download to a billing or data collection com-

puter. Since the meter reader must still go to the site o the meter,

this is sometimes reerred to as on-site AMR.

Wireless

Radio requency-based AMR can take many orms. The more

common types are handheld, mobile, and xed network. Radio

requency (RF) based AMR are available in both one-and two-

way systems, and use both licensed and unlicensed RF bands (see

Figure 22 on next page).

In a one-way system, the transmitter broadcasts read-ings continuously every ew seconds. This means the

reading device can be a receiver only, and the meter AMR

device, a transmitter only. Data goes one way, rom the

meter AMR transmitter to the meter reading receiver.

In a two-way system, a radio transceiver normally sends

a signal to a particular transmitter serial number, signaling

it to activate rom a resting state and transmit data. The

meter-attached transceiver and the reading transceiver

both send and receive radio signals and data.

AMRs are also available as hybrid systems that com-

bine one- and two-way technologies. These types o sys-

tems use one-way communication or reading and two-way

communication or programming unctions.

RF-based meter reading usually eliminates the need or

the meter reader to enter the property or home, or to locate

and open an underground meter pit. The advantages o us-

ing an RF-based meter include saving the util ity money by

increasing speed o reading, lowering liability as a result

o entering private property, and reducing occasions o

missed reads because o being locked out o meter access.

Walk-By

A handheld AMR is a handheld computer that has a built-in or

attached receiver/transceiver (radio requency or touch) to collect

meter readings rom an AMR-capable meter. A handheld AMR

is sometimes reerred to as a walk-by meter reading because the

meter reader walks by the locations where meters are installed as

they go through their meter reading route. Handheld computers

may also be used to manually enter readings without the use oAMR technology.

Drive-By

A mobile or drive-by meter is a reading device that is installed

in a vehicle. The meter reader drives the vehicle, while the reading

device automatically collects the meter readings. For mobile meter

reading, the reading equipment oten includes navigational and

mapping eatures provided by Global Positioning System (GPS)

and mapping sotware. The reader does not normally have to read

the meters in any particular route order; the reader has only to

drive the service area until all meters are read. Components o amobile meter usually consist o a laptop or proprietary computer,

sotware, RF receiver/transceiver, and external vehicle antennas.

Fixed Network

Fixed network AMR is a method where a network is permanently

installed to capture meter readings. This method can include a

series o antennas, towers, collectors, repeaters, or other perma-

nently installed inrastructure to collect transmissions o meter

readings rom AMR-capable meters and get the data to a central

computer without a person in the eld to collect it. There are sev-

eral types o network systems in use to get the meter data back to

a central computer. A star network is the most common. With this

type o network, a meter transmits its data to a central collector or

repeater. Some systems use only collectors which receive and store

data or processing. Others also use a repeater, which orwards a

reading rom a more remote area back to a main collector with-

out actually storing it. A repeater may orward by RF signal or,

sometimes, is converted to a wired network such as telephone or

Internet Protocol (IP) network to get the data back to a collector.

X. Summary

Water meters are the lieblood o a water utility. They indicate

how much water is produced, how much is treated, and how much

is used by the customer. In other words, the meter is like a cash

register. There are varying meter designs, based on specic ap-

plications. There are proper installation procedures or water

meters, and the meters should be replaced when they no longer

properly record water usage. Technological advances have revolu-tionized the meter-reading process with AMR systems.

Depending on the AMR system used, water providers

can:

notiy a customer when normal usage changes;

resolve customer disputes by proling their daily us-

age;

review usage records hourly to determine the begin-

ning and repair o a leak;

monitor odd/even watering days; and even

veriy the fushing o illegal material by examining late

night water use.
