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:
A few weeks ago, I wrote about problems a customer encountered trying to move a functioning radar level device from one tank to another. With a little light reading of the user manual, and one change on the radar, the situation was resolved.
People are usually familiar with the concept of false echo suppression: looking at a tank and mapping out the obstructions that can cause false readings, like baffles, ladders, tank braces. But the Siemens products we work with do it a little differently. It’s a built-in feature on Siemens ultrasonic and radar level devices, and only takes five minutes to run.
