Ultrasonic level sensor with RS485

Ultrasonic level sensor with RS485

HLVR series digital ultrasonic liquid level sensor with RS485 communication, MODBUS-RTU protocol, can read real-time data such as instrument liquid level temperature through the master computer, read and write various custom tags, modify sensor parameters and so on. The liquid level sensor is compact and economical level measuring device. Protection class for the ultrasonic liquid level sensor is IP68.

Technical Specifications
