Soap Foaming Agent Liquid Level Sensor


foaming-soap-agent-liquid-level-transmitterWhen a North Carolina manufacturer of hand cleansers and de-sanitizers needed reliable level measurement of their bulk storage tanks, they turned to Flowline. A critical ingredient is sodium laureth sulfate, a highly effective foaming agent that’s used in most of their products. But this is a challenging liquid to measure that’s sticky, very low dielectric and extremely foaming when agitated. For this reason, Flowline suggested the use of our pulse radar level sensors (that are unaffected by foam) installed in a metal stand-pipe to maximize the RF signal strength and reflectivity off the surface of the low dielectric media. The pulse radar level sensor provides continuous level data to the PLC, which in turn, monitors the tank levels and actuates low level alarms for chemical distributor replenishment. Flowline is reliable level measurement.
