The 15-30-15 Rule in Ultrasonic Level Measurements

Written by: Dan Weise

If I’ve heard it once, I’ve heard it a dozen times when talking with a Siemens support guy while evaluating a problematic ultrasonic level measurement application,
“What’s the echo confidence and strength?” “What’s the noise measurement?”

Those are numbers that quantify the echo quality: the floor values for echo confidence and strength and the ceiling value for the noise.   I’d look up the value and the guy on the phone would tell me whether the number was good, bad or so-so.  Finally, someone wrote down what those values should be, and they’re worth filing for future reference.

Move New Multi/HydroRanger Level Controller Guts into an Existing Multi/HydroRanger Enclosure

Written by: Dan Weise

The venerable Siemens Milltronics line of level controllers, the MultiRanger and HydroRanger Series, recently received a major update. The new models have high resolution LCD displays and built-in configuration tools with English language menus. Configuration time is reduced significantly without the need to reference manuals for parameter codes. These updated models have ‘HMI’ in the model name: MultiRanger HMI or HydroRanger HMI.

Viewing data logs in Excel format (Siemens LUT 400 Ultrasonic Level Controller)

Written by: Dan Weise

Siemens’ LUT 400 saves data values and alarm events in text-formatted log files. This note covers how to get the files out of the LUT400 to view them in spreadsheet format using Siemens Log Importer macro for Excel.

Free Download: Siemens e-book Going the Distance – Solid Level Measurement with Radar

Written by: Dan Weise

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.

Understanding Level Readings & the Truth about Level Measurement Instruments

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 »

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.
