The measuring principle is based on the influence of the flowing fluid to the traveling time of sound.
1.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.
2.The usage of US300PM is not only for the maintenance and the check of your facilities but also for the measurements at laboratories or manufacturing line. The transducers are made for harsh industrial environment.
3.Equipped with a rechargeable battery that can operate for up to 14 hours on a single charge. Comes with an AC adapter.
