Consumption data acquisition with heat meters

Heat meters calculate the consumed energy (amount of heat) using various measuring methods. The basis for this is the water flowed through (volume) and the temperature difference between the supply (flow) and the return. The amount of heat is calculated from these measured values, taking into account a heat coefficient.

A mechanical or static measuring principle is used here. In a mechanical principle, the water flowing through is captured by a rotating impeller. The static measuring method measures the volume using an ultrasonic signal.

In addition to the current value, the Engelmann heat meter stores historical values for the last 24 months. These can be read out either directly from the meter display or via an optional communication interface.

Engelmann offers a wide range of retrofittable communication modules. The range includes both wired variants (M-Bus, Modbus, 2 pulse outputs) and wireless variants (wireless M-Bus and LoRaWAN).

More information on the automatic reading of wM-Bus meters via gateway can be found in the application description “Build AMR network”.
