The liquid is quite viscous and contains some powdered catalyst particles; the temperature is 130 degrees. Sometimes the float gets stuck. Can the problem of sticking be resolved by increasing the weight of the float? When placing an order, how should technical requirements be specified for float balls?
I’m afraid it won’t work in your case; this type of operating condition is not suitable for magnetostrictive level gauges. If you really need to replace the float, you can use one with a larger diameter. If increasing the weight of the float is desired, it is necessary to calculate the buoyant force exerted on the float in the medium after the weight is increased, to ensure that it can remain afloat.
There was a problem with the selection; why wasn’t the viscosity of the medium taken into account from the start?
This operating condition is not suitable for magnetostrictive level gauges; although they can withstand high temperatures, they are not suitable for viscous liquids. This issue can be resolved by replacing it with a high-temperature radar level gauge. 26G or 80G can both solve the problem perfectly.
There is an issue with the selection; viscous media are not suitable for float level gauges. It is recommended to consider high-temperature radar level gauges
If the substance is only viscous without any crystallization or solidification, it is recommended to use a static pressure-based method for level measurement, such as a pressure or differential pressure transmitter with an inserted diaphragm cell. But if the medium may undergo condensation or crystallization, it is better to choose a non-contact type, as that is more reliable.
Radar level gauges might be more suitable than magnetostrictive level gauges
