Operation 13
3.5 TOTAL CONVERSION
The Total Conversion Factor is programmed to enable the rate to be displayed in
one engineering unit and the totals to be displayed in another. For example, the
rate can be displayed in gallons/minute and the totals in barrels.
The Total Conversion Factor is a division factor which is used to convert the totals
to a different unit. Therefore, it only affects the totals (both resettable and
accumulated).
Example.
If the Rate is required in gallons/minute:
1. The Scaling Factor would be programmed as pulses per gallon.
2. The Timebase would be programmed as minutes.
If the Totals are required in barrels:
1. The Total Conversion Factor is programmed as 42 because there are 42
gallons in a barrel. All totals will now totalise in barrels.
Below is a table containing common units and their corresponding Total
Conversion constants:
Rate/Unit Time Totals Total Conversion Factor
Gallons (US)/Unit Time Barrels (oil) 42.000
Litres/Unit Time Kilolitres 1000
Litres/Unit Time m 3 1000
ml/Unit Time Litres 1000
Mgallons/Unit Time Acre-feet 0.32587
