RE: acoustic telemetry using pipeline

Steve,

Station a person at the top of the hill near the tank and one more near the pump. Ask the former to shout at the top of his voice when the tank is full so that the later can switch off the pump. Simple isn't it.

One word of caution: make sure neither of them are deaf or dumb.

Cheers,
Pankaj Mandal.

Hi Al
don't go to any trouble; was just wondering if there is something off the shelf that someone knows of.

Cheers

Steve
