Hi Seth,

My gas meter, (EKM G-4 3/4 " with pulse output) reads in cubic meters. I am using the EKM-EDSPN-Nv.2 Single phase electric meter. What is the correct pulse ratio setting for this set-up? (I am trying to get a cubic feet read out.)

Hello Leon,

The older model (metric) gas meter you have pulses 100 times per Cubic Meter of Gas. This is about 1 Pulse per .353147 Cubic Feet (edited by Jameson to correct an error)

The conversion from Cubic Meters to Cubic Feet is:

1 Cubic Meter = 35.3147 Cubic Feet

Here is a link that lets you make other conversions:

So the number I should enter after the "1:_______" is what?

Leon,

This is for your metric meter only (so those of you with a gas meter that reads in Cubic Feet can ignore this)
100 Pulses = 1 Cubic Meter
1 Cubic Meter = 35.3147 Cubic Feet
1 Pulse = .353147 Cubic Feet
I would set your electric meter to increment 1 every 1 Pulse Input (set it to 1:1)

There is 1 Pulse per.353147 Cubic Feet, so when you count your Pulses multiply number of Pulse Counts times .353147 to give yourself the number of cubic feet. For example if your Pulse Count is 546 you would have 192.82 cubic feet.

Thanks,
Jameson
