Does Fleetwatch do conversions for Propane or CNG to DGE, GGE, or Therms
Conversions are done by the Dispensers

Does Fleetwatch Convert Propane or CNG to DGE, GGE, or Therms?
No. Unit conversions are done at the dispenser, and the converted amount is passed along to Fleetwatch. Fleetwatch records the quantity in whatever unit the dispenser reports.
Who Handles What
|
The dispenser
Unit conversion
Converts the fuel measured (for example, CNG by weight or propane by volume) into the unit you bill or report in, such as DGE, GGE, or therms.
|
Fleetwatch
Pulse rate conversion
Counts the dispenser’s pulses and applies the pulse rate, which sets where the decimal point goes in the final total fuel field.
|
What a Pulse Rate Conversion Looks Like
The dispenser sends a set number of pulses for each unit of fuel. Fleetwatch divides the pulse count by that rate to get the quantity. Example for a CNG dispenser already set to report in DGE:
| Pulses received | Pulse rate | Recorded in Fleetwatch |
|---|---|---|
| 523 | 10 pulses per DGE | 52.3 DGE |
| 523 | 100 pulses per DGE | 5.23 DGE |
Same pulses, different pulse rate: only the decimal point moves. The unit (DGE) comes from the dispenser.
Common Units
| DGE | Diesel Gallon Equivalent: the amount of fuel with the same energy as one gallon of diesel |
| GGE | Gasoline Gallon Equivalent: the amount of fuel with the same energy as one gallon of gasoline |
| Therm | A unit of heat energy (100,000 BTU), often used for natural gas billing |
Quantities look wrong?
• Off by exactly 10, 100, or 1,000 times: the pulse rate (decimal point) is likely set wrong in Fleetwatch. Contact Fleetwatch Support.
• Wrong unit, or off by an odd amount (for example, showing GGE when you expect DGE): the conversion is set at the dispenser. Contact your dispenser vendor or service provider.
