GIWU Series Ultrasonic Flow Meter
Ultrasonic flow meters are the equipment of choice whenever the contact with the measured fluid isn't possible. Ultrasonic measurements are made by attaching two transducers onto the outside of a pipe. GIHU and GIWU series transit time ultrasonic flow meters measure the time difference between the ultrasonic pulse going upstream and the one propagating downstream. These sound waves are generated by a pair of transducers. The difference between the two intervals of time is a function of flow direction and velocity, and it represents an accurate measure for the average velocity of the liquid flowing through a pipe.
