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 (Program Mode 1) to 01.0000
2 Set the Totalizer Decimal Point (Program Mode 2) to 000000
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
Example: 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
