C053 – Gas Totalisation – Pulse Output Meter


This calculates the totals for pulse output based meters where the metered fluid is a gas.

  • Injected frequency
  • Injected pulses

This option is used to select whether the total will be calculated from the flow rate if frequency is chosen or calculated directly using the number of pulses measured.

Enter elapsed time as

  • Duration
  • Start and end time

This option is used to select whether the time over which the totals are to be calculated is entered as a duration or as a start and end time.


  • Use start and end totals

This option allows the user to enter displayed totals for the start and end of the totalisation process for comparison with the calculated results.

The remaining options are the same as are found in K133 – Gas Flow Rate – Pulse Output Meter



If the duration is calculated this is done by:

t1 = End time
t0 = Start time


If injected pulses is selected the totals are calculated from the equation:

If injected frequency is selected the totals are calculated from flow rate by:

IntF = Interpolation factor
MF = Meter Factor
Inj_pulses = Injected pulses
Kf = K-factor
Ctsm = Correction for temperature on steel of meter
Cpsm = Correction for pressure on steel of meter
Q = Flow rate
t = Duration
