A level gauge that can measure the levels of two different fluids – what is it called, and how is it maintained?
Thread Content
There are two types of fluids in the container, and this level gauge can measure the level of both fluids. It has two floats; what is the name of this type of level gauge? If one of the floats does not function properly or stops moving, how should it be repaired? I would appreciate it if experts could explain this to me.
A surface tester should be used; a float alone can solve the problem! This is usually because the float is stuck!
Do you want to measure the liquid levels of the two media separately, or the interface between the two media? Generally, float balls were used in the past, while magnetostrictive devices are used more now
Mostly, multiple float balls are used. If one part gets stuck, the entire system has to be stopped and taken apart for inspection; in other words, if one component is damaged and repairs are needed on another component, it’s necessary to first stop this device. Remove for maintenance!
RF is useful for measuring the level of multi-medium liquids; it is now used in many oil fields for measuring crude oil storage tanks
What the poster is referring to is probably a float level gauge, which uses the density of the medium to calibrate the instrument. RF is used to measure multi-medium liquid levels, and there is no issue of the float getting stuck.
The level gauge mentioned by the poster must be a magnetostrictive level gauge! If one stops moving, it’s most likely stuck; it needs to be taken out and cleaned
You are referring to a magnetostrictive level gauge, which is generally used to measure phase interfaces. It has two gauges and two floats, and these two gauges communicate with each other. It doesn’t move; usually, something dirty is stuck and needs to be cleaned out
This process condition should allow the use of an electrical float level gauge.
