People who have used Milltronics or Siemens ultrasonic continuous level measurement systems are used to the way configuration is done. It’s not uncommon that when they start up their first Siemens radar transmitter they encounter a stumbling block – the 4-20mA output doesn’t respond correctly.
The radar will start up and run, and if the tank level is low, they’ll get a valid level reading on the transmitter’s display, but the 4-20mA will be incorrect (too high a percentage). Or, if the tank level is at a medium or high level, both the indicated level in the display and the output will be maxed out at 20mA. It’s a misunderstanding about where the span measurement starts from. Read the rest of this entry »
