Liquid level sensor is undaunted by sticky fluids
Gill Sensors & Controls
Monitoring levels of sticky or viscous materials is always challenging, as these fluids can lead to clogged float mechanisms, blocked fill ports, solid buildup on moving floats and masked windows. The new Model 7014 high- viscosity liquid-level sensor (photo) has a proprietary conductive technology that is designed for monitoring highly viscous (water-based) liquids. It has an electrically sensitive probe surface and no moving parts or floats, so there is nothing to clog, wear or freeze, allowing for a reliable signal reading while reducing maintenance needs, according to the manufacturer. The probe also features wetted parts manufactured with fluorinated ethylene propylene (FEP). The smooth sensing surface can differentiate between being immersed in thick liquids versus the airspace at the top of the tank or container, enabling more accurate calculation of true liquid level. — Gill Sensors & Controls Ltd., Los Angeles, Calif.
