Honeywell Heat Meters
Honeywell heat meters are the EW700 series ultrasonic heat meters (order codes EW7001AM…) offered by Resideo under the Honeywell brand. Ultrasonic measurement with no moving parts ensures a long service life; the meters can be read out via the standard M-Bus and IrDA interfaces, and the calculator unit stores heating and cooling energy in separate registers. They are MID Class 2 approved, and the manufacturer specifies a battery life of 10 years.
For apartments, sizes from DN20 to DN40 are available. The DN20 (¾") body connects to the pipework with 1" threaded unions.
After installation, Novus Energy also provides remote meter reading and heat cost allocation for the heat meters it supplies. For periodic re-verification requirements, check your local regulations. To compare all brands, see our heat meter prices page.
