Application / Function
The heat meter ultego® III eco is a measuring device for the physically correct recording of the heat consumption. It is
subject to mandatory calibration in Germany and many other countries. The device consists of a volumetric flow meter,
two permanently attached temperature sensors and a calculator, which calculates the heat consumption from the volume
and the temperature difference. The volumetric flow meter is a wear-resistant ultrasonic measuring device without me-
chanically moving parts. The long-life battery is designed for the entire duration of the calibration period. The ultego® III
eco cannot be opened without breaking the calibration seal. The heat meter may only be operated under the conditions
stated in the device documentation and the type plate.
