Product Description

Honeywell EW701 Series ultrasonic heat meters are used for heating energy measurement in hot water hydronic central heating systems. They are typically used for submetering applications in appartments, offices or administration buildings. The meter enables an exact measurement of even very small flow quantities.  

They can be installed in any position. Within the flow there are no moving parts. The EW701 meter do have an extremely compact design height and a detachable calculator unit as standard with Long connection cable for universal use.
