A couple years ago, Siemens published a great handbook on using radar to measure solids levels, but the $60 price tag limited its readership.
You can now download the book for free as an electronic epub file formatted for electronic readers, which in my case, is the Firefox browser on my laptop. It could be any browser (Internet Explorer or Chrome), or presumably any electronic book reader.
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…
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 »
Recently, a customer noticed that the Siemens ultrasonic level measurement system he had installed in a storage bin showed a signficant amount of moisture buildup. At extreme temperature changes (like we’ve seen a lot latele here in the Midwest), there’d be moisture buildup on the Echomax ultrasonic transducer, sometimes so severely, they’d have problems from signal loss.
How could they fix it? One quick trip to the local big-box or auto supply store provided a Siemens-supported solution.

Yesterday and today, people all over Chicago and the Midwest were looking at pictures from last year. We had 22″ of snowfall in one day. The roads were closed. The airports were closed. Even the Lesman offices were closed. And today’s weather forecast? 45°… in Chicago… in February.
This morning in Pennsylvania, a groundhog named Phil came out, looked back, and saw… his shadow.
All this looking back made me a little reflective myself. I’ve been writing this blog for about 6 months now. So I thought I’d take a minute and recap the articles people keep coming back to read:
