How long as it been since the vessel was been cleaned. If both devices share the similar issue I can assume that it may be as simple as plugged taps. If the lower nozzle is located directly under the vessel or close the bottom of the vessel, you may have pookie (What the techs refer to as...
I will have to agree with roydm on this one and thanks for quick specific gravity lesson. Zdas04 the DP meter is the common choice for interface levels. The other common choice are displacer levels, the old mechanical prehistoric reliable means of interface measurement. Radars are percieved as...

I would send the modules to emerson for a failure analysis. They would be interested in knowing how it failed as well. At one time emerson had an issue with 3051 models that had the lighting protection module added to the terminal block. The D/A board as also had issues. Example would be that...
I have worked in the petrochemical industry for several decades. With new technology for instance smart instrumentation and even smarter fieldbus digital instrumentation I still find myself having to scratch my head to remember basic level calculation. Try this application tool.
Here's a demo...
zflee. You did not provide much information, but I assume that you are dealing with a common fire system where the media would be water. I also assume that you would be dealing with building fire systems of unit deluge fire systems. Either way I am going to suggest ashcroft guages. They are a...
