WAGES monitoring example
The following example shows WAGES monitoring for a water flow meter.
You can connect your meter's digital input to a transducer that sends a pulse for every 15 kiloliters
(4000 US Gal) of water. After configuring an input metering channel and assigning it to the digital
input, the meter can detect and record the incoming pulses. An energy management system can
then use the information from the meter to perform WAGES analysis.

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
