One temperature sensor and two transmitters!
Can we connect two temperature transducers to one RTD? We need to maintain the temperature gauge and somehow place a transducer device to get a 4-20 mA output. Do we need to disable the existing gauge and replace it with a temperature gauge with this output? ...
Temperature transmitter calculations
Our temperature transmitter has an input range of 0 to 100 degrees Celsius, an output range of 4-20 milliamps, and accuracy of ±0.5 percent. If the output of the transmitter is 13.6, what are the ideal minimum and maximum temperatures? I calculated between 67.5 and 68.5. Am I right? ...
Compressed air flow measurement on Rosemount 8800D
We have a problem with compressed air flow measurement with the Rosemount 8800D vortex flow meter. Did we pick the wrong instrument for our application? ...
Reliable steam measurement?
What's the best technology to measure high-pressure steam flow? I want a flow meter with high accuracy, reliability, long lifespan, and low cost if possible. Also, is there a portable instrument for measuring steam? ...
Rosemount Raptor go!
Please help me configure our new wireless Raptor! I have no idea how to start working with it. ...
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? ...
Level transmitter calibration!
I'd like to know more about calibration of level transmitters. Do we really need to calibrate these devices? ...
Emerson 5300 GWR and sludge!
We have an Emerson 5300 GWR LT! Sometimes, the level fluctuates severely. After we open and inspect the chamber, we find the rod clean but sludge in the chamber drain. After flushing the chamber, the level goes back to normal. How does this sludge cause this problem when the rod itself is clean? Can ...
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 ...
