METERTEST & CALIBRATE
Description:
This activity involves the monthly testing of supply and distribution flow meters at the pumping station to
ensure an accurate accounting of water supplied by the NWC or Village wells and disbursed by the booster
pumps into the distribution system.
POLYSONIC FLOW TEST
Signal strength should be in the green zone.
Signal processor light should be OFF or blinking between positive and negative.
Sensitivity red light should be OFF and green light ON.
Using sensitivity nob dial setting to get the proper light.
Using calibration setting of 500 range position B - take the percent reading on the dial times 10,
times I.D. of the pipe, times I.D. of the pipe, times .0245 to get GPM, times that by the length of
the test to get total amount of water flowed during test.
A flow counter on meter tester is also taken during test. You multiply counter readying by 10
the I.D. of the pipe times I.D. of the pipe times .0245 to get total amount of water flowed during test.
Checking these readings against the flow counters you are testing.
Take a start reading on the flow counter and then take a stop reading on the flow counter to get total
amount of water flowed during test.
Example:
I.D. of the pipe is 8.18
Percent reading on the dial is 78
Counter on tester is 2334
Test time - 30 minutes
10 x 78 x 8.18 x 8.18 x .0245 = 1279 GPM
7279 x 30 min - 38370 total gal
2334 x 10 x 8.18 x 8.18 x .0245 = 38263 total gal
flow counter stop 0043
start 0005
Total gallons 38000
38000 divide 38263 = 997o acatracy
FOXBORO HAND HELD
Hook up foxboro to flow tube transmitters positive and negative terminals.
Go to measure from the main menu on the foxboro you will see (3) things displayed:
4 - 20 mA signal
Inches of H2o
Vo flow
To get GPM from a mA signal, you need to take max GPM that the transmitter is scaled to and
divide by 16, that will give you GPM/mA. Take the mA reading on the foxboro, subtract (4) Ma,
then take that reading times GPM/mA to get GPM at that mA signal.
To get GPM from inches of H2o, you take the inches of H2o on the Foxboro, divide by the max
inches of H2o that the transmitter is scaled to, times max GPM that the transmitter is scaled to,
times max GPM that the transmitter is scaled to, then find the square root of that answer, this will
give you GPM at that inches of H2o.
To get GPM from Vo flow, take max GPM that the transmitter is scaled to and times it by the Vo flow
reading on the foxboro that will give you GPM.
If you take GPM times length of the test, you will get total amount of water flowed during test.
On the flow counter you are testing, take a start reading and then a stop reading to get the total
amount of water flowed during test.
Take the total amount of water flowed during test form the mA signal and compare it to the total
amount of water flowed during test of the flow counter you are testing.
Example:
Transmitter max GPM 6000
Transmitter max inches of H2o 41t.46
5O% flow
12mAreading
102.86 inches of H2o reading
1.

mA signal
6000 GPM divide by 16 = 315 GPM/mA. 12 rnA minus 4 mA = 8 mA times 375 GPM/mA =
3000 GPM times 30 min. = 90000 gal
Inches of.HZo
102.86 inches of H2o divided by 41I.46 times 6000 GPM times 6000 GPM = 8999563. Take
that and find the square root = 3000 GPM times 30 min = 90000 gal
Vo flow
6000 GPM times SOVo = 3000 GPM times 30 min = 90000 gal
flow counter
start reading 00110, stop reading 00198 = 88000 gal
88000 gal divided by 90000 gal = 98%
(To get inches of H2o at known GPM)
(GPM divide by max range of GPM that the transmitter is scaled to) times it=s self - times max
range of inches of H2o that the transmitter is scaled to equal inches of HZo at know GPM.
To get GPM from known inches of H2o
Takes inches of water, divide that by max inches of water that the transmitter is scaled to, times
max flow in GPM that the transmitter is scaled to, times max flow in GPM take the answer and get
the square root of it.
