Liquid level measurement scheme for furfural evaporator
Thread Content
Dear teachers, which brand of level gauge is suitable for measuring the liquid level in furfural evaporators? It can be domestic or imported; the medium is very diverse and highly corrosive.
Pressure, temperature, medium composition, evaporator structure? Only by clarifying these can everyone help with the selection!
Furfural evaporators are also corrosive; therefore, if the accuracy requirements are not particularly high, lined magnetic flap valves or external float level gauges can be considered. Magnetostrictive and guided wave radar level gauges are also options available. The choice ultimately depends on factors such as process parameters and the type of evaporator
Temperature: 200, acidity: 3, medium is complex; a waxy layer forms on the liquid surface when it’s cold. Pressure: 16 kilograms. The medium is corrosive and contains acetic acid.
Use double-flange or contactless radar level gauges; it is recommended to use imported ones such as e+h, Rosemount, EJA, etc
We can consider using weighing methods to indirectly obtain liquid level information; compared to level gauges, it is not affected by the type of medium or temperature, and no openings are required. It has its advantages and disadvantages relative to level gauges.
