APG MNU Specifications

APG

Modbus/Tank Cloud Ultrasonic
Sensor
Series: MNU

®

The MNU series sensors utilize standard Modbus RTU protocol (RS-485). The MNU is designed to work as a slave
device. With the ability to measure volumn and distance, the MNU is the ideal sensor for your application.

Features

• Ranges from 4 in - 40 ft

• Self-Contained Sensor

• RS-485 Modbus RTU Interface

• Measure Distance, Level, or Volume

• Internal Temperature Compensation
