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:
