The Pyxis LS-200 is a general purpose, innovative, ultrasonic liquid level sensor. It replaces float, conductance, and pressure sensors which generally fail due to contact with dirty, sticky, and scaling liquids in small, medium, and large capacity tanks.




(Ultrasonic level sensor)

The Pyxis LS-200 is a general purpose and innovative ultrasonic liquid level sensor that replaces float, conductance, and pressure sensors which fail due to contact with dirty, sticky and scaling liquids in small, medium, and large capacity tanks. These liquid level sensors can be used in both open or closed tanks. It provides a continuous level of measurement up to 86 inches (2.2 m) with a 4-20 mA signal output, RS485, and Bluetooth digital output. It can be configured via the free uPyxis® app for both smartphones or desktops. These sensors can be powered by a 24VDC external power source via the 10’ output and power supply waterproof cable provided. This non-contact liquid level sensor is well suited for corrosive liquids chemical or process tank applications.
