In an ideal world there would be a perfect liquid level measurement system that would work for every liquid and every application. Unfortunately, that product does not yet exist, leaving operators and technicians to go through the trial and error process of finding the level instrumentation that will work for them.
So in this high-tech world, is there still a need for the old faithful pneumatic systems like air bubblers? The answer is YES! Why? Because air bubbler systems work when other systems fail.
Air bubbler systems will work with the more difficult of liquids such as…

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:
Ran into a situation last week that taught me an important lesson.
A customer took a tank out of service for major repairs, so they moved the Siemens radar level transmitter to a different tank. Even though the radar unit performed flawlessly on the first tank, they ran into difficulty getting the correct level readout in its new installation.
The mechanical guy had moved and remounted the transmitter. The I&E tech had wired it correctly, and then did a master reset before starting a fresh configuration. After going through the configuration, he couldn’t get a valid level readings in the upper fourth of the tank level.
The second tank was near its full level and the technician (properly) wanted to wait to do an Auto-Learn scan until the tank level approached empty. In the meantime, we were all scratching our heads trying to figure out why the upper level readings were not correct.
In frustration, I finally resorted to pulling out a manual . . . Read the rest of this entry »
Looking for a programmer for your radar level unit, and can only find the ultrasonic version? Need the ultrasonic, but it’s disappeared? Not to worry: You can use either Siemens/Milltronics handheld programmer in a pinch!
Those Siemens handheld programmers are the same size and sorta look alike until you look closely. One is for radar, the other for ultrasonics. What if you can only locate the Wrong One? Read the rest of this entry »
Do you need to send an instrument to the factory for repair or service? Before you disconnect it, pack it up, and ship it out, be sure you do the following:
- Make a backup or copy of your instrument configuration, so you can quickly reinstate the settings.
- Make sure you have a written record of your settings on file. Several manufacturers include a configuration worksheet in the instrument user manual. If it’s not there, you can write them on a copy of the quick-start or setup installation guide.
