Does ultrasonic level measurement work with a standpipe?

The easy answer: Yes.

But in a recent webinar on choosing the best level technology for your application, the more specific answer is this: Yes, AS LONG AS you pay attention to the unit specs and a pretty simple rule of thumb.

How to keep condensation from affecting Siemens ultrasonic level sensors

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.

LUT400 universal 4-20mA analog output gets rid of the ground loop

The Problem
Before I talk about the value of a universal 4-20mA analog output on a level controller, let me explain why anyone would care. It’s all about ground loops.

Since the early days of electronic instrumentation, way back when, even before cell phones or PCs, instrument people struggled with ground loops that create an offset error, drive the signal off scale, or burn up an analog circuit.

A “So What” review of Siemens new SITRANS LUT400 ultrasonic level controller

Part of my job as the technical specialist at Lesman is to make sense of new products and upgrades, and figure out what’s really going to matter most to our customers.

Sometimes it’s just a matter of a much-needed new functionality, or better configuration tools, easier mounting, or switching to the most current form of data storage.

In the case of Siemens’ latest ultrasonic controller, it’s all that and more.

Siemens SITRANS LUT400 Ultrasonic Level ControllerSiemens (and Milltronics) ultrasonic controllers and transceivers, like the HydroRanger, MultiRanger, and OCM-III have been around for years with no significant improvements. Instead of updating these devices, Siemens has done a complete redesign, and introduces the SITRANS LUT400 as the first device in the new ultrasonic controller family.

Here are my initial thoughts on this new player in the ultrasonic game.
