The Panametrics PT878 clamp-on ultrasonic flow meter is universally regarded as the best portable ultrasonic flow meter and can be used to measure a wide range of clean and dirty liquids, even with some gas bubbles or solids. It can be used on pipes from 0.5 inch to 300 inch (12.7mm to 7.6m) on all metals and most plastics without the need to cut into the pipe.

The PT878 portable ultrasonic flow meter can be set to log up to 100,000 data points which can be downloaded to PC via its USB port . The data can then be exported to csv file and viewed in excel format.
The PT878 portable flow meter is a compact transit time (time of flight) portable flow meter suitable for a wide range of non invasive flow measurement applications. It has a wide range of optional transducers and clamping fixtures to suit all types of rugged industrial environments.

The PT878 clamp on flow meter is an easy to use flow meter which can be easily installed and up and running within minutes. The user simply has to enter the site parameters, clamp the transducers onto the pipe and adjust the spacing.
