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.
