[. . . ] FOR HEATING AND COOLING APPLICATIONS PRODUCT DATA EW447-EW452 Series Mechanical Heat Meters Application Static compact heat meter with electronic measurement, consisting of electronic energy integrator and mechanical volume measuring component. Metering of hydronic heating and / or cooling energy in hydronic systems based on volume, supply and return temperature. EW447-EW449 models are suitable for energy metering of heating systems. [. . . ] The meter can be conveniently read from a single line seven-digit display with units and symbols. A pushbutton provides user friendly control of the various display loops. All failures and faults are recorded automatically and displayed on the LCD screen. To protect the reading data, all relevant data is saved in a non-volatile memory (EEPROM). This memory saves the measured values, device parameters and types of error at regular intervals. Mechanical volume measuring component The technology of the volume measuring component permits very high measuring accuracy and can be used in the supply or return pipeline. The volume measuring component meets the requirements of EN1434 / class 2 and 3.

The service loop displays the current data for flow rate, temperatures, power, volume and next reading date. A button is mounted on the front panel of the meter. This can be pressed for a short or long time. A short press of the button (< 3 seconds) switches to the next display within a loop and a long press (> 3 seconds) switches between the display loops.
