Automatic water cut-off device

Can automatic water cutters also be used on liquefied hydrocarbon spheres?

Float-type, electronic sensor type, ultrasonic type, radar type. Liquefied hydrocarbons are generally sent to dehydration tanks, not automatic dehydrators; it’s not safe to use them

The general principle of float-type and buoy-type devices is the difference in density； In the case of electrons and ultrasonic waves, it is generally the difference in the reflection of electrons or sound waves by water and oil. The principle of the float type is the same as that of the float in a toilet tank, only the approach is reversed. The buoyancy of water is greater than that of oil. The density of the float is greater than that of oil but less than or close to the density of water. When the water level reaches a certain height, the float rises and opens the valve; once the water has been drained, the float drops and closes the valve. Liquefied hydrocarbons can also be used. I’m just worried that there could be a significant risk of leakage if it fails; to increase reliability, I want to add an automatic emergency shut-off device, but that would raise the costs. With what happened with those ten technologies recently, I guess no one would dare to use it. Many of us go too far in trying to correct things.

We carry out direct dehydration; the dehydration line is equipped with two valves – a gate valve installed at the tank base, and a spring valve as the second valve
