s ENVAULT is designed with a

SCADA system at the core,

many functions are available that are

beyond the capabilities of traditional

web based data presentation package.

One of these is the ability to displayanimated graphical representations of

sites, or mimics as they are named in

SCADA terminology.

The ENVAULT mimics can:

Automatically update as new

data arrives

Graphics can be as detailed or

realistic as desired

As values and current statesupdate, this can be used to

modify symbol colours or

behaviour

Mimic symbols can be selected

or clicked, allowing pop-up

windows with more detailed

information

Network diagrams showing site

interconnections work

especially well, withENVAULT totalisation or

mass balancing possible

The mimic features have all the same

licence features of the ENVAULT

subscription in that there is no limit to

the number of users that can

concurrently connect to the your

stations. Additional engineering time

is the only extra cost, to allow for

completely customised mimics

showing your specific site arrangement

A

hile measuring environmental

conditions is the cornerstone of

our business, some conditions are not

easily measured or quantified, or need

to be visually verified to ensure a true

and accurate historical record. Images

captured at specific times or on-events

can by used to qualify measured data

or quantify non measured information.

A typical application is to capture a

photo of the water surface when a

turbidity reading is collected, or a

sample is taken to allow the operator to

see conditions that may be affecting

the reading. Other applications

include images to supplement noise

and blast projection data, plant stress

conditioning, security monitoring (as

shown in the image here), wildlife

activity or any parameter that cant be

easily measured. Images stored are

archived for future analysis

arrah Watson recently completed

the initial phase of a new Data

Acquisition System roll out for

Manitoba Water Stewardship (MWS).

This system is now running in parallel

with the legacy NewLeaf system toallow users to become familiar with

the new software as Manitoba prepares

for an expected epic flood season after

record snowfalls this year.

EnviroSCADA is an innovative

telemetry solution developed by

Greenspan that extends the industrial

strength ClearSCADA platform by

adding the capability to support most

popular environmental dataloggers.

This technology has already been

successfully implemented at a number

of project sites and also underpins

Greenspans own hosted telemetry

solution, ENVAULT .

The EnviroSCADA installation for

MWS acquires data from 376 sites

across Manitoba, consisting of:

283 GOES (satellite)

25 Dialup land-line sites

68 Manual (files copied to a

Hot Folder for automatic

ingestion into EnviroSCADA)

Flood forecasting is one of the

principal activities of Manitoba Water

Stewardship with water level and

water temperature being the main

types of sensor data collected at each

telemetered site.

The second phase of the project,

scheduled for June this year, will

include the addition of an Aquarius

client/server system integrated with

EnviroSCADA to allow MWS

personnel to edit data, generate rating

curves and ultimately provide quality

approved flow data for flood

prediction models.

JWater stored

as snow from

the snowfallseason will

be unlocked

once the

warmer

months

arrive,

resulting in

higher than

normal flood

conditions.

alculation of flow is important in

many areas of Greenspans work,

from flood warning systems through to

irrigation modernisation. A suite of

techniques and instruments exist to

suit the variety of conditions, hazards, budgets and resultant accuracy

requirements, each with their unique

set of limitations and site

requirements. Some of difficult

conditions typically encountered are:

High flow velocities, especially

during flood

Backwater effects from tides,

confluences or constrictions

causing hysteresis

Rock, debris or other damaging

objects in the flow

Vandals or thieves that target

riverside instruments

The need to be able to visit and

service the instrument in all

flow conditions,

Lightning strike potential

exacerbated by long cable runs

We are proud to introduce the Sommer

RQ-30 Surface Velocity Radar which

measures the surface velocity of the

flow with a Doppler velocity radar,

and the corresponding level with a

radar level, safely above the river

surface, solving many of the problems

identified. The instrument features:

Waterproof IP68 construction

Operates from low surface

velocities all the way through to

extremely fast surface

velocities, up to 15 m/s

Internal inclination sensor

automatically adjusts for the

angle of the measurement

Bi-directional flow capable

Multiple radar velocity sensors

into a single RQ-30 station for

measurement of surface

velocity distribution over wide

or variable rivers

Radar level which is unaffected

by temperature, unlike

ultrasonic level sensors

Small, compact design

including small solar powered

telemetry option for

communications direct to onsite

SCADA or hosted online

SDI-12, RS485 or independent

analog outputs for measured

level, measured velocity and

calculated discharge.

Detects river bed changes

Low power consumption suited

for solar power operation

Mounted from a bridge, arm,

raised platform or even a

riverside mast (not necessarily

overhead)

Onboard theoretical flow

models for standard structures,

which can be refined by onside

calibration (to convert surface

velocity to flow totals)

Consult your Greenspan representative

for help with instrument selection to

suit your site, particularly in sites with

any of the listed difficult conditions.

he back page features items that

we cant quite make into full

articles but are nevertheless worth

noting. This quarter we highlight:

The flooding recently

throughout Australia hasaffected many of our staff and

clients directly. To help in

getting conditions back to

normal, Greenspan and Tyco

staff have donated over $40,000

to the flood relief efforts, to

help our local communities get

back on their feet.

Steve Bailey has recently

retired from managing

Campbell Scientific Australiaafter 18 years as Managing

Director. With several staff at

Greenspan having previously

worked for and with Steve, we

all want to wish him the best

during his retirement, and may

it be a long one!

Singapore International Water

Week is coming up this June

and Greenspan will again be

part of the Aquatic Informatics

booth, as their Asia distributor.

Justin Stockley and Glenn

McDermott recently presented

at the 2011 Asia Pacific Water

and Sewer Systems Modelling

Conference held at the Gold

Coast, with their paper titled

Cost Effective Verification of

Sewer Hydraulic Model Design

Storm Simulations.
