Water Meters Pulse Factors

You can identify from the Honeywell (Elster) Bulk Water Meter H4000 dial plate the following:
• Which type of pulser to use, i.e PR7
• The pulse factor, i.e P:1

Pulse weight is calculated by multiplying the register ‘pulse factor’ (P) by the PR7 ‘K-factor’ (K);
• Pulse Weight (Litres per pulse) = P x K.

Please note that the available sizes are 40mm to 300mm for flow rates of between 0.35m³/h and 2000m³/h.
