Input metering

Your meter’s digital inputs can be used to count pulses from transducers and convert the pulses to energy measurements.

Your meter’s input metering channels count pulses received from the digital inputs assigned to that channel. The incoming pulses are used in calculating and measuring consumption data (e.g., BTU, kWh, L, kg). Each channel must have the following values configured to match the pulse data:

  • Pulse Weight: the pulses per unit value.

  • Unit Code: the unit of measure associated with the monitored value.

  • Demand Code: for time-based values (such as kWh), this provides the associated demand units (kW) for demand calculations; for other values (such as kg), this can be configured to provide rate information (kg/h or kg/s).

  • Mode: whether a pulse is based on a complete pulse or a transition.

For example, if each complete pulse represents 125 Wh, you can configure for Wh pulsing as follows:

  • Pulse Weight = pulses/Wh = 1/125 = 0.008

  • Unit Code = Wh

  • Demand Code = kW (this is automatically set)

  • Mode = pulse

If you want to configure for kWh pulsing, you must adjust the pulse weight calculation and unit code as follows:

  • Pulse Weight = pulses/kWh = 1/0.125 = 8

  • Unit Code = kWh
