Yokogawa US300FM Ultrasonic Flowmeter
Production Description
The model US300FM is an ultrasonic flowmeter for measuring liquid flow in a fully filled pipe. With the advanced signal processing and correlation detection method, US300FM provides fast, accurate, and no-zero offset flow measurements in clean to dirty fluids.
Comes with transducers in three sizes that accommodate pipe sizes from 25mm to 6500mm
