fraction of pulse per gallon?

I have a flowmeter that provides 4-20 output for flow rate and also has an "odometer" for flow total. There is also a pulse output from this device whose spec is given as .26000 pulses per gallon.

I will invert that spec to get 3.486153846 gallons per pulse, but why would a manfufacturer specify a value like that? In this context, how would anyone measure a fraction of a pulse?

If you multiply .26 times 3.875 (gallons to liters), you will get it in liters per pulse which would equal 1.00 liter per pulse. Most of the the flow meters I work with you can configure the meter into whatever units you are looking for (gallons, liters, grams, etc).

Doh!! I dont know why that didnt register. Thanks for that.
