Energy calculator multidata WR3

Heat calculator for heat- und cooling meter

The calculator multidata WR3 is used to measure heating and cooling energy in closed circulation systems.
This is a so-called split heat meter, for which a calculator, flow sensor and temperature sensor pair are

High level of compatibility

The multidata WR3 is a real all-rounder that can be combined with nearly all standard temperature sensors and flow sensors. A special version is available for flow sensors with a high frequency pulse output.
All appliances allow the connection of both the flow sensor and two additional appliances via the pulse
generator as standard, e.g. a cold and hot water meter.
The meter readings can be called up via the menu on the appliance or via reading systems.

Suitable for heating and cooling

The multidata WR3 is optimally suited for the measurement of heating and cooling energy. The measured
consumption values for cold and heat are saved in separated registers. Areas of application are air-conditioning systems in which both heating and cooling energy is emitted through the same pipeline network.
