How should one choose a level gauge in such a situation?
Thread Content
Mine is an evaporation kettle, vacuum-type, made of enamel material, with stirring; the medium is corrosive. What type of level gauge would be suitable? The differential pressure is selected; the density varies ； Radio frequency admittance is used; there is stirring and steam ； Radar options are expensive ； If a level switch is used, stirring will have a significant impact on the float-type level switch; moreover, it’s difficult to make openings in enamel reactors ； Use an external ultrasonic level switch; it’s a vacuum environment after all. Could everyone give some advice? Thank you.
With stirring in place and the rotation speed not being very high, is it possible to use a float-type level switch for controlling high and low liquid levels? Is it stable?
The mixing tank operates intermittently, not continuously, right? It is said that a flow meter can be installed at the inlet to enable calculation and quantitative production
A level switch or a magnetic float level gauge can be used, but a static well needs to be installed to ensure stable operation.
Choose a magnetic float level gauge with an external opening for regular cleaning of dirt
A level electrode can be used. Given the presence of corrosion, it is likely that the environment is one with strong acids or strong bases; the medium should have a certain level of electrical conductivity. The presence of spare ports is convenient in such cases. If the corrosivity is not high, a 316L electrode can be used; in cases of extremely high corrosivity, graphite electrodes should be employed. Since stirring takes place, the distance between the two electrodes should be more than 10 centimeters
For a cost-effective option, use a magnetic float level gauge; remember to drain it regularly
Insufficient parameters provided. Avoid using radar if possible: it’s expensive and extremely unreliable!
Reply to 9# Forum Wanderer: “Avoid using radar if possible: it’s expensive and extremely unreliable!” "Does it mean it’s not suitable for this case?
If the position of the liquid level sensor in your mixing port is large enough, I would recommend using a 4-wire radar system along with a sleeve; if there’s an opening on the side, then many options are available. As you mentioned earlier, it’s not easy to create such an opening.
