Go to content Go to main menu 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 required. 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.
