Let’s take a look at what kind of level gauge should be used in such a situation!

We have storage tanks with a capacity of 100 cubic meters for storing this viscous material, which crystallizes at 36 degrees and tends to form foam. The float level gauges currently in use don’t work very well; I was wondering if anyone has any good level gauge suggestions. Please advise! ! !
I would like to know a few more things: Is the container fully sealed? The density of the medium? What type of float was used before? What is the density of the floating ball? What is the temperature of the tank? Is it necessary to measure the temperature? If crystallization occurs at 36 degrees, the temperature inside the tank must be lower than this value for the medium to flow properly; foam formation in the product is a challenge in terms of measurement. In my opinion, if it is a fully sealed tank, a magnetostrictive level gauge should be considered; the density of the float ball should be close to that of the medium being measured, so as to prevent the float ball from being lifted by foam. At the same time, a magnetostrictive level gauge can be used to measure temperature, ensuring that it remains below 36 degrees at all times ； If it is not a fully sealed tank, consider using a flanged level gauge for measurement, or a pressure transmitter with a flush diaphragm structure that can be installed with clamps for easy removal and cleaning ；
Regarding the conditions of the materials stored in your unit’s tanks, since these materials tend to crystallize and form foam, it is essential to consider providing heat tracing for the tanks in order to prevent crystallization from accumulating at the bottom of the tanks. It is also important to maintain a certain liquid level during operation, ensuring that the gauge interface remains below the liquid surface; this helps to avoid the gauge interface from being exposed to the surface where evaporation can occur, leading to crystallization. Ordinary level gauges are unlikely to meet these requirements. In processes involving evaporation and concentration that result in crystalline products, similar problems often arise. Based on practical production experience, using radio frequency admittance level gauges or insert-type differential pressure transmitters (such as those produced by Shanghai Guanghua Instrument Co., Ltd.) yields good results.
The steel belt level gauges used in our unit perform well with media that have high viscosity and high temperatures. These level gauges are inexpensive, but their measurement accuracy is poor; therefore, more maintenance and inspection are required.
What about the radar locator? It should work, but it’s expensive, around 10,000 or so.
