I was bored, so I searched it out.

I eventually searched Altavista for "liquid flow sensor" and found a bunch
of wrong things, and a few good things.

I don't know if it will blow up with something flammable, but by the looks
of it, it is designed to be safe. I would ask them, anyway.

It doesn't provide pulses for it's output, but rater a 0-5v signal,
corresponding to a 0-100% flow.

They provide a few other flow sensors -- high pressure, Teflon coated
innards some that provide pulsed output, etc. Have a look at:

Also, just found this, and it looks like this could be a _great_ help. Just
put in all your specs, click search, and it lists all that look like they
might be what you want.
