Electronic heating cost allocation device Minometer® M7, hereinafter referred to as “distributor”, is designed to measure the temperature difference between the surface of the heater and the temperature of the surrounding air and calculate, based on the measured temperature difference, a number proportional to the amount of heat energy released by the heater.
The set of indications of distributors in the collective heating system allows to allocate the share of the costs of each apartment from the total house costs according to the indications of the general heat energy meter and to calculate the heating costs for each consumer of an apartment building.

Minometer valves are used in the field of housing and communal services.
