Yellow phosphorus level measurement
Thread Content
I need to measure the level of yellow phosphorus in a metering tank. The tank uses a water seal, which causes stratification: the upper layer is water while the lower layer contains yellow phosphorus (with a density of 1.8). Yellow phosphorus turns into a solid at 40 degrees Celsius. How can I measure the level of yellow phosphorus? I seek advice from those with experience!
What are the standard requirements for the design of underground tanks for yellow phosphorus!
Currently, a top-mounted magnetic float level gauge is being used, and the situation is fairly good. Cable-type capacitive level gauges are also used, but it is necessary to calculate the height of the water seal and that of the yellow phosphorus separately; however, if phosphorus sludge adheres to the cable, it can easily cause damage to the cable. It is important that the temperature in the tank not be too low, as this could cause the yellow phosphorus to solidify, and it must remain in a molten state
Keeping the water level at full capacity works well with a capacitive level gauge
