I'm looking for a way to remotely measure the depth of the water in a cistern that's about 250 feet away from the house without running a wire across the road between them. They share a power transformer, so I'm either looking for something wireless or power-line that'll transfer an analog signal from a pressure transducer or ultrasonic depth (height) gauge. The water depth is on the order of 4 feet maximum, if that matters...
Someone here must know of something! Thanks!
I'd use a transponder. cork on a rope connected to a dial. Shine a light on the dial. The dial responds by reflecting the measurement. High Tech ain't always required. mike
