Anyone got on advice on a decent oil tank alarm please? Must be

Thanks. I think a lock might just cause more problems as any thieves
will just drill a hole in the side and syphon off the contents.
What's needed is an alarm like the Watchman but which also has a
tamper proof mechnism so it can't simply be removed or somehow
disabled.

I've got a Watchman-sonic tank level monitor, which works perfectly.

Seems they do a similar alarm system as well:

I was looking at the Watchman - looks good, but is it tamper proof? I
mean what's to stop some enterprising thief from unscrewing it, so
preventing it from sending an alarm to the receiver?

Or, for that matter, somehow shielding it so that it can't send an
alarm to the receiver?
