A magnetic flow meter (mag flowmeter) is a volumetric

flow meter which does not have any moving parts and is ideal

for wastewater applications or any dirty liquid which is

conductive or water based. Magnetic flowmeters will generally

not work with hydrocarbons, distilled water and many non-

aqueous solutions. Magnetic flowmeters are also ideal for

applications where low pressure drop and low maintenance are

required.

There are some condition before you install the flow meter :

Meaning of measurement, accuracy, type and condition of

fluid, pressure of the pipe, measurement range, power supply,

environment condition where the flow meter will be place.

These cost-effective magnetic flow meterscombine superior noise immunity with high purityAlumina ceramic detection tubes, allowing precise flowmeasurements in a wide range of applications. Thesemagmeters are available in pipe sizes from 1 /2 " up to16" to accommodate many materials: chemicals,corrosives, foods, pulp and other solid matter slurryflows. The FMG-600 Series electromagnetic flowmeterunique noise-suppression circuitry utilizes the optimumsquare-waved excitation frequency, eliminating variousnoises generated by slurries, making this flowmeterideal for pulp, food and grout applications.

The FMG-550 Series fits pipe sizes from 2 to 48". The

standard connection is a 1¼" NPT. It features an integral display

for flow rate or totalization. The latest in bipolar pulsed dc

technology and the best features of an insertion magnetic flow

meter sensor are packed into the FMG-550 Series insertion

magmeter. The FMG-551 is a magnetic flow meter to meet your

flow measurements challenges. Simple installation, easy

maintenance, and state-of-the-art microprocessor technology

make the FMG-551 the best alternative to traditional full-line

magmeters. The FMG-551 electromagnetic flowmeter generates

an isolated current output and an isolated frequency output. The

current output provides a universal signal to recorders, valves,

and a host of process control and data acquisition devices.

The FMG3000 and FMG3100 Series are for 0.5 to 8 in.

Pipes. These are blind transmitter with either a 4 to 20mA or

frequency output. All versions of this magmeter are constructed

of corrosion-resistant materials to provide long-term reliability

with minimal maintenance costs.

The FMG201 Series is a small plastic-bodiedmagnetic flow meter capable of measuring the pulsatingflows from air and solenoid-driven metering pumps, themeter is primarily designed for electrically-conductivechemicals and fluids of varying viscosities. The FMG201electromagnetic flowmeter is an ideal flow measurementdevice for low flow applications. In addition to measuringand displaying flow rate and total flow, this magmeter unithas a variety of outputs. For continuous transmission of aflow signal, there is a 4 to 20 mA, and 0 to 5 volt signal, anda frequency signal proportional to flow. In addition, thereare relay alarm outputs for low and high flows with user-setflow levels

Type Difference

In line Magmeter(FMG 606)

Ideal for pulp, food and grout

applications

Style Mag Flow Meter(FMG 551)

The current output provides a

universal signal to recorders,

valves, and a host of process control

and data acquisition devices

Style Mag Flow Meter( FMG3002)

Same as FMG 551

Low Flow Magmeter(FMG201)

An ideal flow measurement device

for low flow applications

Usually electrochemical and other effects at the

electrodes make the potential difference drift up and

down, making it hard to determine the fluid flow

induced potential difference. To mitigate this,

the magnetic field is constantly reversed, cancelling

out the static potential difference. This however

impedes the use of permanent magnets for magnetic

flowmeters.
