ULTRASONIC FLOWMETERS
The measuring principle is based on the influence of the flowing fluid to the traveling time of sound. The sound is transmitted through the pipe and the transit time difference between the forward and backward directions is used to determine the flow velocity (transit time method).

	US300FM Series Ultrasonic Flowmeters The US300FM series ultrasonic flowmeters measure fluid flow using non-intrusive ultrasound technology, eliminating the need to cut through pipes. With its clamp-on transducers, installation is quick and easy, and measurement is independent of fluid pressure or conductivity.
	US300PM Ultrasonic Flowmeter (Portable type) The model US300PM is a portable ultrasonic flowmeter for measuring liquid flow in a fully filled pipe. With the advanced signal processing and correlation detection method, US300PM provides fast, accurate, and no-zero offset flow measurements in clean to dirty fluids.
