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
