The Huba Control flow sensor type 210 is a non-moving vortex sensor for measuring the flow of liquid media. Thanks to the piezoelectric principle, the measurement is stable over a wide range of temperatures, the sensor is not sensitive to common impurities in the medium, and causes only minimal pressure loss. The DN8 design is particularly suitable for heating and cooling circuits, and also for drinking water. The sensor is available with frequency, voltage, or current output, in versions with or without temperature measurement (depending on the chosen version).
