By counting these pulses the meters kWh value can be calculated. Unlike clip-on CT based monitoring, pulse counting is measuring exactly what the utility meter is measuring i.e. what you get billed for. The pulse counting cannot provide an instantaneous power reading like CT based monitoring can. Where possible, we recommend using pulse counting in conjunction with CT monitoring. The emonPi ...

pulseIn() - Arduino Reference

Reads a pulse (either HIGH or LOW) on a pin. For example, if value is HIGH, pulseIn() waits for the pin to go from LOW to HIGH, starts timing, then waits for the pin to go LOW and stops timing. Returns the length of the pulse in microseconds or gives up and returns 0 if no complete pulse was received within the timeout. The timing of this function has been determined empirically and will ...

What is the best way to use a pulse meter with Niagara?

The counter is very useful as it takes the "Current Pulse Count", converts it appropriately and adds to a local counting value all the pulses counted by your strategy or directly by your IO module. If the counter input resets to "0", the local counter will be maintaining its counters healthy and will keep counting all the new data without losing your valuable Energy / Volumetric Flow values.
