Air Bubbler Systems for Liquid Level Measurement

Lesman Instrument Company will build you a customized air bubbler system to meet your company's exact needs. A complete bubbler level measurement system consists of a source of compressed air, an air flow restrictor, sensing tube, and pressure transmitter.
In this video, Nathan demonstrates how the air bubbler system works and explains how it can be used in wastewater systems, wells, and vented/open tank applications.
Lesman is the premiere Midwest US representative and distributor of valving and process instruments for pressure, temperature, level, and flow measurement and control.

Very cool system...

Thanks for the demonstration. I work at a wastewater treatment plant and we have these for level measurement.

Excellent demonstration. Thanks :)

We have 2 smith and loveless liftstations that run on a "bubbler" at the city I work for. Pretty reliable but we are phasing them out for submersible pulps with transducers

During purging doesn't the system need a gauge protector since you are applying direct instrument pressure to the dip tube? You did not mention about your system having a protector system for the transmitter during purging, which i feel is very important.

Hi there excellent demonstrations and I really enjoyed it.. Can you explain where the concept of back pressure comes in this type of instrument?
