Ultrasonic Liquid Level Sensor with Display & Alarm – 4–20 mA / RS485, Low-Volt
A non-contact ultrasonic liquid level sensor designed for reliable level monitoring in tanks, reservoirs, and vessels. Featuring an integrated LCD display, configurable alarm outputs, and industry-standard signal interfaces, this sensor is ideal for industrial monitoring and automation applications without direct contact with the measured fluid.
This ultrasonic liquid level sensor provides continuous, non-contact measurement of liquid levels using ultrasonic time-of-flight technology. By mounting above the liquid surface, it eliminates direct exposure to corrosive, dirty, or hazardous liquids, reducing maintenance requirements and extending service life.
The sensor supports standard 4–20 mA output and RS485 communication for seamless integration with PLCs, RTUs, SCADA systems, and industrial monitoring platforms. An onboard LCD display allows for local level indication, while configurable alarm functionality enables threshold-based alerts for high or low level conditions.
Designed for industrial environments, the device operates from a low-voltage DC supply and is intended for fixed installation within compliant control systems. This product is supplied as a measurement and indication device only and must be integrated into a properly designed automation or monitoring system.
