Calibrating field transmitters
For measuring the liquid level in a close tank, we have a differential pressure transmitter with a flange-mounted remote seal. The application range is from -56mbar to 6 mbar. I have a DRUCK DP610 calibrator, but I couldn't calibrate the transmitter in the field. Any ideas? ...

Unreliable density reading
We have a Micro Motion Coriolis, the CMF300 with 3500 RFT, to measure the density of condensate in a custody metering skid. Now it's not reading correctly. It shows almost 1000 kilograms per square centimeter, but it should be around 700. How do we solve this problem? ...
Coriolis mass flow reading variation
We have three Coriolis mass flow meters for ethylene, one on the main battery limit and the other two on different reactors. Their meters should match the main battery's meter. Right now, we have one to two tons per kilogram of difference, with the battery limit showing less. Can anybody help me sol ...
