237  

Type 237 flow sensors operate according to the vortex principle, which is based on the Kármán vortex street. This non-mechanical measuring method enables precise and wear-free flow measurement without recalibration. The robust Stainless steel construction ensures high long-term stability and reliability, even in demanding environments. The sensor is designed for Medium temperatures from -15 to +125 °C and is suitable for applications ranging from cryogenic cooling to high temperature processes, such as in injection moulding plants. Integration into existing systems is greatly simplified by the M12x1 connector with IP65 and the plug-and-play design. The type 237 was developed for OEM applications that require precise, maintenance-free and long-term stable flow measurement.
