Air Bubbler Systems: Old Faithful Liquid Level Measurement

In an ideal world there would be a perfect liquid level measurement system that would work for every liquid and every application.  Unfortunately, that product does not yet exist, leaving operators and technicians to go through the trial and error process of finding the level instrumentation that will work for them.

So in this high-tech world, is there still a need for the old faithful pneumatic systems like air bubblers?  The answer is YES!  Why? Because air bubbler systems work when other systems fail.

Air bubbler systems will work with the more difficult of liquids such as…

sewage, sludge, drainage water and any other liquid with suspended solids.  They can be used in small diameter pipes, reaching areas that other systems can’t.  Bubblers will not fail if there is foam on the surface of your liquid tank or in the presence of vapors.  And because the point of measurement has no electrical components, the bubbler systems can be used in hazardous areas. Plus, an air bubbler system can be used in temperatures exceeding 350° F.

In the past, if you wanted a bubbler for your liquid level application, you had to buy all the components (a source of compressed air, air flow restrictor, sensing tube, and pressure transmitter), and assemble them yourself. But that’s not the case anymore. We can help. Lesman Instrument Company will build you a customized air bubbler system to meet your company’s exact needs.

In this video, our bubbler specialist Nathan introduces the components of an air bubbler system, demonstrates how it works, and explains how it can be used in wastewater systems, wells, and vented/open tank applications.
