Utility Energy Monitoring System – Gas, Water & Electricity

Hanwell Pro Energy Monitoring Sytem and Utility Management System

Electricity, Gas & Water

The Hanwell Pro energy monitoring system and utility range is an innovative monitoring solution that measures and records utility usage over time and allows statistical analysis of kilowatts/hrs, cubic meters of gas and liters of water consumed. It can quickly identify and eliminate areas of waste, resulting in significant savings within weeks of installation.

The reported data can then be used to provide logged records as evidence of sustained usage reduction over time. Hanwell Pro utility transmitters can be added to existing Hanwell Pro environmental monitoring systems providing a cost-effective solution to utility monitoring.

Utility sensors can be deployed across a site with minimal disruption. There is no need to disconnect electrical supplies as utility devices use split core current clamps to monitor electrical circuits.

Each unit measures the output of current clamps providing fast and reliable information about energy usage and cost. Find specification information on our clamp product pages.
