WFN571-E000H0

Impeller type heat and cooling energy meter, wall-mounted, nominal flow rate 0.6 m3/h, with IrDA interface & AMR radio communication

Stock no. S55561-F191

Stock no. S55561-F191

The electronic, mains-independent impeller type heat and cooling energy meter set is of compact design and used for the physically correct acquisition of energy consumption. The meter consists of a flow measuring section, 2 ready connected temperature sensors and an integrated processor which – based on flow rate and temperature differential – calculates the energy consumption.
