Why Calmet PM02?

Calmet PM02 combines the fast supply and service of a meter made in Türkiye with MID-approved ultrasonic measurement. Using the same series from DN20 to DN100 makes it easier to manage all metering points of a residential complex with one reading infrastructure.

Installation, Reading and Re-verification

Install the meter in the position and at the mounting point specified in its manual; a strainer upstream of the meter and an isolating valve before and after it (for easy replacement) are recommended. In Türkiye, Novus Energy also provides remote meter reading and heat cost allocation services after installation. Periodic re-verification requirements for heat meters depend on local regulations; see our re-verification and calibration page for details.
