The Impact of Background Echoes on Ultrasonic Level Measurement

Photography is a pretty good way to illustrate the importance of background.
Look at the two photographs here. In one, the background is minimal, and focuses your eye on the subject matter. In the other, the background seriously detracts from the subject. Where should you be focusing? What’s most important?
But unlike photography, where a good background helps you focus on the subject, in the world of non-contact ultrasonic level measurement, even a “good” background has a negative influence. Background never contributes to a level reading, it only detracts. But Siemens has a built-in function to “cure” for the influence of backgrounds in their level devices. Read the rest of this entry »
What is false echo suppression?

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.
