Product Description
The Vortex 200 flow sensor is based on the Karman vortex street principle. Vortex flow sensors have no moving parts and are therefore resistant to contamination. In addition, these sensors feature low pressure drop and high measurement accuracy. Models with integrated temperature measurement are available as an option. The sensor has received VDE Mark certification in accordance with the EN IEC 60335-2-40 standard and is specifically designed for use in propane (R290) heat pumps.
