Domestic Heat Meters


The Evinox ultrasonic heat meter range has been designed for use in both heating and cooling residential metering applications. The meters employ the latest technology to guarantee high quality and outstanding long-term measurement stability. The sensor body is constructed from brass and features no moving parts, making it virtually maintenance-free.

The meters feature high quality paired PT1000 temperature probes to ensure performance according to the EN 1434 standard, and can operate with water temperatures up to a max of 95°C and nominal pressure of 16 bar.

Evinox heat meters are available with the following display / body configurations:-

  • The fixed head mounting option features a fully rotating head and is suitable for use in standalone metering applications or for use in simple metering stations.
  • The remote head option features a separate ultrasonic body with remote display head mounted using a bespoke fixing bracket. This is for use in our ModuSat® HIU range or other suitable appliances.
