The 300S Series Submersible Level Sensor provides continuous level measurement for both corrosive and non-corrosive liquids. These submersible hydrostatic transmitters have been designed for the toughest industrial applications. Unlike ultrasonic level transmitters, our liquid level sensors are completely unaffected by any foam, vapor, turbulence or condensate in the tank.

The 300S Series Tank Level Sensor works by sitting at the bottom of the tank and measuring the head pressure of the liquid pushing down on its stainless steel sensing diaphragm. The only submersible level sensor with an integral molded weight to ensure the sensor will remain at the bottom. 

With a 316 stainless steel body, these level sensors have been engineered to handle some of the toughest applications. All models come equipped with a Teflon® jacketed cable and a Kalrez® O-ring seal to ensure it stands up to the industry’s most corrosive chemicals.
