PR-7200 Pump-powered Water Level Bubbler

The PR-7200 is an update to the model previously known as the PumpPro 6150. Similarly the core sensor module is available as a PR-7100 which replaces the LevelPro 6100. The new PR sensor design has identical functionality as previous models, but with modern electronics to allow for future functionality.


The PR designation refers to it being a “Pressure, Remote” sensor, as opposed to out PS range of “Pressure, Submersible” analogue and logging sensors.

The PR-7200 combines an air compressor and a PR-7100 liquid level sensor to form a fully self contained hydrostatic pressure sensor designed to measure water and liquid levels reliably and accurately. Featuring a Teflon-lubricated precision piston air compressor, the PR-7200 is a highly reliable all-in-one water level sensor capable of measuring up to 70m of water head – more than twice the range of traditional bubbler systems.

It has all of the features of the previous model 6100 and 6150 including volumetric calculations for tank-based applications, analogue and digital outputs, an integrated LCD for easy setup, and the optional 8-pin screw terminal connector. Our three year warranty is a testament to the reliability of the components in this unit. On the market for almost 20 years, this design has proven that the days of limited life of pump-style water level sensors is well and truly a distant memory.
