The Aquatape Level Gauge is a packaged system for monitoring levels in water and water-based non-corrosive materials. Applications include rivers, reservoirs, wells, waste water, potable water, sea water and municipal sludge. The Aquatape system consists of the unique resistance-tape sensor, a compact filter assembly, a sensor housing and a 4-20mA current transmitter. It is available in overall lengths of 3 to 50 feet (1 to 15 meters). The filter assembly protects the sensor from moisture and contaminants and provides pressure equalization.
