WSN525-BE

The WSN5.. heating/cooling meter is a measuring instrument used for the physically correct acquisition of energy consumption. The device consists of a flow measuring section made of high-tech plastic, 2 ready connected temperature sensors, and an electronic unit which calculates the energy consumption from the flow and the temperature differential. The WSN5.. is of compact design and therefore ideally suited for use in apartments. It is available in different versions for metering heat or cooling energy.

Please note that national approvals for the billing of cooling energy may have to be considered for combined heating/cooling energy meters.
