What kind of level gauge should be selected?
Thread Content
There is a full-flow channel on site, with the medium inside being a mixture of oil and water; the density of the oil is 1.06. It is necessary to keep the oil level from rising too high, as otherwise the water will flow out through it. If the oil level gets too high, the oil will flow out as well, which is not desirable. Therefore, I would appreciate it if you could recommend a suitable level gauge. Thank you.
Refer to the ZGJD type oil-water dual-level gauge
1. The density difference is too small; if there’s also phase mixing, things will get even more complicated. Measuring the interface, in my opinion, is basically unreliable. 2. Adapt as necessary – don’t measure the interface! It’s those silly kids who are in charge of measuring the interface, {:3_51:} 3. If there is always water in the floating layer, and it can be ensured that water remains there at all times, then it’s possible to achieve 100% prevention of accidental discharge by monitoring the density in the area 30 centimeters below the overflow opening! Why can there be 0% misclassification? What are the criteria for judgment? Bro, I have a question for you guys. Those who are clever should take a look at this diagram and think about it. 4. In a few years, I’ll retire, so I won’t be selling watches anymore. Instead, I’ll sell ideas to earn money from you all to support myself in old age :lol
Can ultrasound or radar be used to solve the problem?
A guided-wave radar level gauge or a radio frequency admittance level gauge can both be used. Can a float work well when the specific gravity is so close? !
Using my stu01 liquid layer detection switch instead of a densitometer provides higher reliability.
