LS-202 Ultrasonic Level Sensor

Liquid Level Sensor with a Local Display.

Monitor for liquid level up to 106 inches (8.8ft / 2.7m) with this simple to operate Ultrasonic Level Sensor.

Made In USACE Mark




The LS-202 is a general purpose ultrasonic liquid level sensor that replaces float, conductance and pressure sensors that fail due to contact with dirty, sticky and scaling liquids in small, medium and large capacity tanks. This liquid level sensor can be used in either open or enclosed tanks. The sensor provides continuous level measurement up to 106 inches (8.8ft or 2.7m) with a 4–20mA signal output, RS-485 and Bluetooth® digital output. Alternatively, the sensor can be powered by (4) AA alkaline batteries or a 24VDC external power. This battery powered, and Bluetooth® digital output enabled level sensor is perfectly suitable for applications where wires are difficult to layout saving end users substantial monetary benefits during installation. A 1.3″ push button OLED interface allows for device configuration and instant access to process data. This non-contact liquid level sensor is well suited for corrosive liquids, and can be used for cooling tower, boiler dry tank, and other chemical feed applications.
