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:
Since Lesman started focusing on level instrumentation 15 years ago, we’ve seen a lot of change. High-tech solutions bring higher accuracy, the ability to automatically eliminate tank obstructions for fewer false readings, the ability to measure level in almost any medium, and even send data from remote tank level systems to a control room miles away.
So is there still a need for more traditional, pneumatic systems, like air bubblers? Absolutely! And why? Because there are still applications where DP, capacitance, ultrasonic, and radar level systems just won’t work.
