FIELD CALIBRATION
Field calibration consists of determining the exact transmitter pulse output per unit of measure for your particular meter/
transmitter combination and then using this value as the transmitter pulse output value when calculating the counter and
time base values . The procedure is as follows:
1 . Set the
Totalizer Scale Factor
to
1
.
2 . Set the
Totalizer Decimal Point
to
OFF
.
3 . Reset the counter to
0
.
4 . Run fluid into a weigh tank or into a calibrated vessel .
5 . Determine the number of pulses per gallon by dividing the indicator reading by the number of gallons of fluid in the
vessel . Use this value for your calculations .
ExampleE:
You programmed the indicator for calibration and connected the outlet of a 1" OP meter to a calibrated vessel . You
opened the valve and allowed fluid to flow into the vessel . You determined that there were 22 .35 gallons of fluid in the vessel .
The reading on the indicator is 1720 .
1720 / 22.35 = 76.95
The transmitter output is 76 .95 pulses per gallon . Use 76 .95 when calculating the
“Totalizer scale factor” on page 10
