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 ...
Measuring boiler blowdown water?
Our boiler blowdown water is in a critical transition between water and steam, so the water has pockets of steam with the dissolved solids. What is the best way to measure the water? Will the vortex flow meter work? ...
Pulse or analog for custody transfer?
Since most Coriolis transmitters provide both pulse and analog 4-20 mA outputs for the reading, which works better for liquid custody transfer where the reading goes to a flow computer and why? How about the digital HART output from the transmitter? ...
Critical spares for plant instruments
I have to choose the critical spares for our plant instruments. I need to consider instrument reliability, manufacturer reputation, lead time, pricing, etc. I don't have any data on instrument failure in this plant. I'd appreciate if someone here can tell me how to design a good critical spares stra ...
