Ultrasonic Liquid Level Sensor

The Ultrasonic Liquid Level Transmitter is a non-contact, highly reliable solution for level measurement in industrial and environmental systems. It uses ultrasonic wave reflection technology to detect liquid or solid levels with accuracy up to 0.5–1.0%, making it ideal for applications in sewage plants, water reservoirs, chemical tanks, and fermentation systems.

 

Product Introduction

IP68 0.5%-1.0% 4-20Ma Ultrasonic Water Level meter Ultrasonic liquid Level sensor

Ultrasonic level transmitter is a non-contact, high reliability, cost-effective, easy to install and maintain level measurement instrument. It is a low-cost measuring device for measuring liquids, slurries and solids at industrial sites. It is widely used in water treatment, municipal, chemical, metallurgical and mechanical manufacturing industries.

 

What Is an Ultrasonic Liquid Level Transmitter

An ultrasonic liquid level transmitter works by emitting high-frequency ultrasonic pulses from a sensor probe. These sound waves reflect off the surface of the material and return to the sensor. The time taken for the echo to return is converted into distance, allowing accurate level detection.

Because it's non-contact, it eliminates problems like corrosion, clogging, or wear — making it low-maintenance and cost-effective.
