Clamp-on flow measurement without pipe penetration
The BBFM-Q1M-D is a 1 MHz ultrasonic flow measurement transducer designed for external mounting on a pipe. Applications include clamp-on ultrasonic flow meters, pipeline flow monitoring, temporary flow testing and installations where pipe penetration is undesirable.
