All the ones I saw had a hose that was filled with a
quantum vacuum. When the car rolled over the
hose it collapsed the wave function and a muon
was fired down the hose. The round thing at the end
of the hose, mounted on a wall usually, accelerated
the muon to super luminal speeds at which point
thousands of leptons were released and when they
hit your head, it made you think there was a ringing
sound due to the observer effect.

The hoses were air filled with capped ends, and the pressure
differential flipped a switch and that powered a solenoid which then
struck the bell.
Same thing for road lane vehicle counting machines which cops put
out in place to place from time to time.
Air works just fine.

Hydraulic bells may have been common somewhere, and I can see how
they would work - but they were unheared of here. As often as we
replaced the air hoses, the oilw ould have been all over the apron.

Here is a you tube explanation for the old bells.

Maybe ask the NASA tranny...that old fool takes 10 minutes to explain 5 seconds of material.

Actually some of the earliest patents going back to 1892 Electrical Hose Signaling Apparatus used a battery for power. Were there even gas stations in 1892? I'm pretty sure there weren't many, it must have been used for something else at the time.
