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…

Understanding Level Readings & the Truth about Level Measurement Instruments

In order to understand level readings, you must first comprehend how the instrument works. Three of the most common level-measuring techniques involve using a displacer, float, or differential pressure instrument.

Here’s the catch.

While each of these instruments can be used to report a level reading, none of them actually measure level.

I know what you’re thinking…

If none of these instruments measure level, how do we end up with a level reading? Read the rest of this entry »
