LL-104 Liquid Level Switch

 

**The new model of the LL-104 Liquid Level Switch is the HT1620.

 

The SuperSwitch™ LL-104 Liquid Level Switch is the ideal solution to a host of liquid level sensing and control applications. It uses proven ultrasonic technology to operate in virtually any liquid, regardless of viscosity or aeration. Its small size and standard 3/4″ NPT mounting make it the perfect choice for new or existing applications. The LL-104 consists of a 316SS sensor and an integral miniaturized, encapsulated electronic control unit which is mounted in a cast aluminum, explosion-proof, watertight enclosure.
