A level gauge that can detect leaks in oil tanks – does anyone with expertise know how to deal with this?
Thread Content
Recently, I saw that gas stations require the use of level monitoring systems capable of detecting leaks in underground oil tanks, and the regulations state that magnetostrictive level gauges are preferred. Could you please explain the principle behind triggering this alarm signal? That is, what conditions will trigger an alarm?

I really dislike you, someone who is active on this forum – every sentence you write is in dialect; I don’t know where you learned that. Can’t you type properly so that everyone can understand? I don’t dare to judge your skills; maybe they are quite good, but using vulgar language all the time is truly annoying No one scolds you?
I mainly want to ask what the principle behind this leakage detection alarm is I didn’t understand it clearly from Baidu searches, so I’d like to ask an expert for some guidance.

Bro, you’re quite a notable figure – there’s no need for harmony in society!
In my opinion, what the original poster is calling a leak detection is actually just a measurement of the liquid level in the underground storage tank. As for this alarm signal, one needs to first understand the working principle of the magnetostrictive level gauge; its display unit can output an analog signal of 4-20mA, and I’m not quite sure whether it has alarm contacts for output as well. Of course, magnetostriction isn’t necessarily required here.
As I understand it, magnetostrictive technology is like a regular magnetic float level gauge with an additional remote transmitter; therefore, the principle of alarm generation should be the same as that of ordinary transmitters – an alarm threshold is set, and the signal is sent to the SIS or DCS system
