Consumption data acquisition with heat meters

Heat meters calculate the consumed energy (heat quantity) using various measurement methods. The basis for this is the water flowed through (volume) and the temperature difference between the supply (flow) and the return. This is calculated with a heat transfer coefficient. This results in the amount of heat.

A mechanical or static measuring principle is used here. In a mechanical principle, the water flowing through is detected by a rotating impeller. The static measurement method, also called ultrasound, measures the volume based on the time difference (transit time difference method) of a sound signal.

In addition to the current value, the heat meter also stores historical values such as the end-of-month value or the reference date value. These can be done either directly on the meter via the display or via the optional communication.

As optional communication there are cable-bound variants (M-Bus, Modbus, pulse output) or wireless (wM-Bus, LoRAWAN). The most common variant is the radio variant. This usually refers to the wirless M-Bus. This can be read out walky-by, i.e. with software and a radio receiver, or stationary (AMR) with a gateway. More details can be found in the application description “Build AMR network”.
