The 15-30-15 Rule in Ultrasonic Level Measurements

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

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.
The text files are extracted from the LUT400 over a USB cable (mini B type connector). When the USB cable is connected to your PC, the LUT400 appears as a removable drive (circled in red, below)
Why won’t Pactware work with the Siemens LUT 400?

I’ve used Pactware for a couple years now, so I was surprised when I couldn’t get the Siemens LUT400 to work with the software. The LUT400 ultrasonic level and flow controller comes with a DTM file that I installed before opening the Pactware software.
The DTM file can be downloaded from this link: http://tinyurl.com/cqk2cky
Once it had been installed, I opened Pactware and updated the device catalog, as seen in the picture below:
But when I attempted to establish a HART connection to the LUT400, I got an error message:
How to Measure Thermal Energy

As energy costs and environmental concerns continue to rise, we count on our facility managers to take control of building/factory energy consumption. To reduce their companies’ carbon footprints, facility managers have begun implementing energy management programs to control their systems, optimize efficiency, and manage expenses.
But how are they doing it?
Let’s say you are trying to cool your facility. There are two steps to determining how much energy is consumed in the process. Read the rest of this entry »
