Stock no. JXF:WFM5..

The compact, electronic and mains-independent impeller type meters WFM5.. are used for the physically correct acquisition of energy consumption. They are available as wall-mounting versions in different sizes and have been developed for heat, combined heat/cooling or solar energy metering.

The meters consist of flow measuring section, 2 ready connected temperature sensors and a built-in processor which – based on flow rate and temperature differential – calculates the energy consumption.

The consumption values can be read out either on the meter itself or from a remote location. Using modules, the noncommunicating meters can be upgraded for readout via AMR (WFZ56.OK), walk-by (WFZ566.OK) or M-bus (WFZ51).

The communicating meters are available as sets with premounted add-on modules.

The WFx5.. are used primarily in plants with central production of heat or cooling energy, where the energy is supplied via zones to several individual consumers in the building.

The meters are supplied with Operating and Mounting Instructions in the following languages:

Bulgarian, Croatian, Czech, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Lithuanian, Norwegian, Polish, Slovakian, Slovenian, Spanish and Turkish.
