The NEW Series PUX Ultrasonic Flowmeter utilizes the transit time difference principle for measuring flow rates through pipes from the outside. This liquid flow meter is compact, portable, and lightweight, incorporating the latest breakthroughs in digital signal processing and electronics. In addition, the Series PUX ultrasonic flow meter realizes high performance and easy operation. One of the most attractive features of these ultrasonic flow meters from the PUX Series is the non-invasive setup, which enables multiple flow measurements of different running systems and offers a significant cost advantage over time.     The Series PUX ultrasonic flow meter may be set up with a wide variety of sensors from small diameters to large diameters, over a wide temperature range.
