Totalizer Programming
Totalizer values can be expressed in any engineering unit of measure such as gallons, quarts, or liters . For each unit, a unique
scale factor must be programmed .
Totalizer scale factor
To determine the Totalizer Scale Factor (Program Mode 1), use the following formula:
Totalizer Scale Factor = 1/(Transmitter pulses per unit X Decimal Factor)
where:
Transmitter Pulses per Unit is the number from the chart at the right, or the literature for your particular transmitter/
meter combination . The chart is expressed in gallons and liters . If you wish to read in other units, use the appropriate
conversion factor .
Decimal Factor (from 1.0 to .001) determines the resolution of the reading . If you wish to read to the nearest 1/10 unit, the
Decimal Factor would be 0 .1 .
ExampleE: You have a model 35 RCDL meter with a PFT-2 transmitter that has a pulse output of 126 .7 pulses per gallon . You
wish to read the totalizer to the nearest tenth gallon .
1/(126.7 X 0.1) = 0.0789 (scale factor)
1 . Set the Totalizer Scale Factor (Program Mode 1) to 0.0789 .
2 . Set the Totalizer Decimal Point Factor (Program Mode 2) to 0.0 (one decimal place) .
Rate of Flow Programming
Rate of flow can be expressed in any engineering unit of measure for any time base such as gallons/minute, liters/second,
barrels/hour .
Rate scale factor
To determine the Rate Scale Factor (Program Mode 4), use the following formula:
Rate Scale Factor = (Seconds / Transmitter Pulses per Unit)
where:
Seconds is the number of seconds in the rate time unit . If you wish to read flow in units per minute, seconds would equal 60 .
If you wish to read flow in units per hour, seconds would equal 3600 .
Transmitter Pulses per Unit is the number from the chart to the right or the literature for your particular
transmitter/meter combination . The chart is expressed in gallons and liters . If you wish to read in other units, use
the appropriate conversion factor .
Before you program the Rate Scale Factor, you must set the Rate Decimal Point position (Program Mode 3) . This decimal point
will correspond to the decimal in the Rate Scale Factor number .
ExampleE: You have a model 35 RCDL meter with a PFT-2 transmitter that has a pulse output of 126 .7 pulses per gallon . You
wish to read rate of flow in gallons per minute .
60 seconds /126.7 pulses per gallon = 60/126.7 = 0.473(rate scale factor)
1 . Set the Rate Scale Factor Decimal Point (Program Mode 3) to X.XXX .
2 . Set the Rate Scale Factor (Program Mode 4) to 0.473 .
3 . Since we are reading in whole gallons, set Rate Decimal Point (Program Mode 5) to off .
