描述

EW500 Series Electronic energy calculators were designed for use with ultrasonic or mechanical flow sensors and 2-wire Pt500 temperature sensors. The combination of EW500, flow and temperature sensors provides fluid energy metering of heating and chilled water systems.Metering of hydronic heating and / or cooling energy in hydronic systems based on volume, supply and return temperature. Suitable for energy metering of cooling, heating and combined cooling and heating systems.

Features

  • Two slots for retrofittable communication modules
  • Replaceable battery
  • Extensive readable data memory
