Multifunctional Sonde


The multifunctional sonde is a compact, high precision volume flow sensor, which additionally also constantly measures the medium temperature, pressure and the thermal energy. Energy measurement is based on two sensors: a flow meter to measure flow and a pair of temperature sensors (flow and return flow). Energy usage is determined by calculating temperature difference between the input and output of the system. Designed to be directly integrable into an heat exchanger, it provides an extensive monitoring of several important values.
