What type of level gauge is suitable when the viscosity of the oil is very high?
Use a differential pressure level transmitter or a non-contact level gauge, such as radar.
Due to the high viscosity, differential pressure level transmitters are not suitable; a non-contact level gauge is better. Such as radar, light guides, but expensive
Positive displacement flowmeters and mass flowmeters can also be used
For the 3 sets of separators, we use differential pressure level transmitters; for the large tanks, radar sensors are used, and fiber optics are also employed in some cases

In fact, the differential pressure method can be used: insert-type double flanges or flat double flanges (with a slightly downward installation angle) can be selected, and negative migration of the differential pressure transmitter is also an option.
Non-contact is better; using radiofrequency sodium guidance is also acceptable, as long as there is no material on the measurement tube.
Pay attention to what the other person is asking about; they are referring to a level gauge, not a flow meter.
Micro-vibration level gauges still have certain requirements regarding viscosity; it is necessary to determine just how high the viscosity is.
The ammonia level gauge used in our unit’s benzene workshop is a magnetic float level gauge (with remote transmission), but due to the poor separation of oil and ammonia in the ammonia pressure oil, oil gets carried into the ammonia container and causes condensation, which renders the magnetic float level gauge ineffective. What type of level gauge should be used in a situation like this?
(Back upstairs) Insert-type capacitive level gauge – it works well for measuring oil content in synthetic ammonia, and it can also withstand high pressures. Of course, there are many other options for low pressure. Last edited by lbxx2008 on 2007-12-11 09:36]
I’m sorry, haha; I stayed up too late that day and made a mistake. A penalty is deserved: loveliness:
In our benzene plant, float level gauges of the type with a sink barrel are commonly used for monitoring the ammonia level in the containment tanks; sometimes waste oil ends up inside these sink barrels, which leads to inaccurate level readings. Additionally, our plant has four ammonia containment tanks equipped with float ball indicators, and these have worked well without any instances of failure being observed.
