The Enistic Smart Pulse Meter is a flexible interface that links water, gas or electricity meters into the Enistic Energy Management system. With a wide variety of input options, the counter is designed to give a 0.01% accurate feed of meter values into the software system.

It communicates these values wirelessly, using ZigBee Pro, to Enistic's Energy Manager Online software, which allows simple calibration for a range of interpretations of the pulse, such as whether it is gas, water or electrical, and the meaning and value of each pulse.
