Clamp-on ultrasonic flow meter M-Flow PW- Converter - FLR
This clamp-on ultrasonic flow meter applies a measurement method based on transit time difference. By taking advantage of the latest electronics and digital signal processing technology, we have developed a device characterized by its excellent immunity to air bubbles and its extreme accuracy. A communication function (MODBUS: optional) is also available.
