Storage tank level indicator
Please, could you suggest the best level indicator on a storage tank application? The tank will have methanol and ethyl acetate along with a sticky material. We need to avoid tank overflow! ...
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 ...
Endress+Hauser FMP51 output signal
Hi. We have an E+H Levelflex FMP51. The output is not changing proportionally with the level, and we already checked the output in the control room for different currents. We simulated the output from the transmitter function menu and transmitter responded, and all other related parameters checked o ...
Wireless device on established system?
We need a new level and temperature system for a pump controlled by the process variable, and we want to go wireless. Can we set up a wireless device in the field and incorporate it into our current business planning and control system (BPCS)? ...
FOUNDATION Fieldbus or HART?
Hi. Both FF and HART can provide field data to the marshalling cabinet. Which is more reliable for the oil and gas industry? ...
Yokogawa ROTAMASS flow direction
Hello. Do you have any experience with ROTAMASS? Last week our ethylene flow meter suddenly went to zero in the DCS, but the actual flow was normal. We reversed the flow direction, and the flow became normal. Now the actual flow direction is forward, but the transmitter configuration is reversed. Wh ...
Pharmaceutical plant asset management
Hello. I work at a pharmaceutical company, and we need options for plant asset management and condition monitoring. Could you tell me more about PAM and help me come up with ideas for our 4-20 mA plant? ...
Level transmitter malfunction
We have the Endress+Hauser Levelflex FMP51 installed on a diesel tank for level measurement, but its output is not changing proportionally to the tank level. In the control room, we simulated different currents from the transmitter function menu and the transmitter responded fine. What do we need to ...
