Product Description

Honeywell EW773 Series ultrasonic meters are static compact heat or chilled water meters with electronic measurement based on the ultrasonic principle, consisting of an electronic energy calculator, an ultrasonic flow sensor and two temperature sensors.

They are used for metering of hydronic heating and/or cooling energy in hydronic systems based on volume, supply and return temperature. EW7730 models are suitable for energy metering in heating systems only. EW7731 models are suitable for energy metering in heating, cooling or combined systems.
