Ultrasonic Level Gauge: A Leading-Edge Device for Precision Measurement of Liquid and Foam Height [Dayu Electronics]
An ultrasonic level gauge is a leading-edge liquid level measurement device known for its high accuracy, strong reliability, and excellent repeatability, suitable for level measurement in various liquid and foam environments.
Working Principle of Ultrasonic Level Gauge

By transmitting high-frequency sound waves into liquids and foams, the ultrasonic level gauge measures the height of liquids and foams by utilizing the propagation speed and attenuation characteristics of sound waves in these media. The working principle is as follows:

1. Measuring Liquid Level Height
The sensor of the ultrasonic level gauge emits high-frequency sound waves into the liquid. Since sound waves travel relatively quickly through liquids, they are absorbed and reflected by liquid molecules. By measuring the time and intensity of the reflected sound waves, the ultrasonic level gauge calculates the liquid height.
2. Measuring Foam Height
When foam is present in the liquid, the lower density of the foam causes sound waves to propagate relatively faster through it, and the reflection time of the sound waves is shorter. The ultrasonic level gauge calculates the foam height by measuring the time and intensity of the reflected sound waves.
Installation Methods for Ultrasonic Level Gauge

The sensor of the ultrasonic level gauge typically consists of a high-frequency sound wave sensor, housing, bracket, and antenna. The following aspects should be noted when installing the sensor:
1. Fix the sensor inside the equipment, ensuring an appropriate distance from the liquid and foam.
2. Securely attach the antenna and bracket to the equipment to ensure accurate positioning.
3. Firmly install the housing inside the equipment, ensuring its structure and dimensions meet the requirements.
