    Description of the device The CALOR 38 heat meter is based on measurement principle by a well-known Faraday's electromagnetic induction law according to which an electric voltage is induced during the flow of a conductive liquid through the flow meter magnetic field. This is sensed by two electrodes which have direct contact with the measured medium and evaluated in the electronic unit, taking into account the temperature difference of the paired resistance temperature sensors on the supply and return pipes.
