Precision and accuracy in energy metering

In times of increasing energy costs, it is important to measure and control energy consumption accurately. We meet our costumers' requirements by offering a variety of highly advanced heat metering instruments. Heat meters are used to measure the physical flow of energy used for heating.

The modern measurement technology consists of a flow meter, two temperature sensors and an electronic calculator with LCD display. The first sensor measures the flow temperature and the second temperature sensor is used to detect the return temperature of the heating/cooling circuit. From the resulting temperature difference, flow and heat transfer properties the consumption is determined.

Ultrasonic Heat/Cooling Meter

Precise measurement of energy consumption

The heat/cooling meter generation ultego III with their different series and sizing provides a multitude of combination and application possibilities. In the compact version ultego III smart and perfect range consists of a calculator, flow sensor and temperature sensors. The calculators can be removed and mounted separately and the two external sensors specified at a number of lengths to meet all requirements. Both series can be provided with a number of integrated communication modules and are compliant to the European Measuring Instruments Directive MID.
