Hi All
Can you please let me know which level instruments are better to measure the level of the oil on top of the water.The is around The tank is a closed tank.
Thank you

Guided wave radar is good for interface provided that the hydrocarbon dielectric constant is not too low. Normally this is not a problem. Magnetostrictive is not avvected by the dielectric. I prefer different technologies for the process control and safety shutdown measurements. I might look at GWR and magnetostrictive first; then consider other technologies.
I tend to avoid capacitance level instruments due to several issues.

A regular DP cell will work if you can get taps above and below the interface but you need to be carefull with the instalation detail.
We also use differential bubble tubes (Tantalum) in a particuarly nasty application. It's crude, old fashoned but it works very well.
Nuclear works well.
The Oil Patch still use a lot of displacers.
