Liquid level detection is an industrial process …agricultural irrigation…Environmental monitoring is a common technology in urban areas. The purpose of liquid level detection is to determine the height or changes in liquid level in the container, in order to monitor, control, and manage the operating status of the liquid in real time.Measure liquid levelSeveral common detection methodshaveFloat type liquid level detection、pressureType liquid level detection、capacitanceType liquid level detection、ultrasonic wavelevel detection.Each method has its applicable scenarios and limitations. When choosing a liquid level detection method, it is necessary to comprehensively consider factors such as specific requirements, liquid properties, and environmental conditions. Meanwhile, it is also necessary to pay attention to selecting appropriate liquid level sensors and monitoring equipment to ensure the accuracy and reliability of liquid level detection.

Ultrasonic liquid level detectionyesDetecting liquid level by emitting ultrasonic waves and measuring their reflection time. The speed of ultrasonic propagation between liquid and air is different, and the liquid level height can be determined by measuring the propagation time of ultrasonic waves. Ultrasonic liquid level detection is non-contact and suitable for various liquids, but may be interfered with when used in liquids with many bubbles, particles, or vapors.

Liquid level detection technology plays an important role in industrial production and daily life. It can not only improve production efficiency and safety, but also save resources and protect the environment. With the continuous development of technology, liquid level detection technology is also constantly innovating and improving, providing more accurate and intelligent liquid level monitoring solutions for various industries.

What factors affect the measurement range?

1.The medium and temperature of liquids: Ultrasonic waves propagate at different speeds in different media, so the medium and temperature of liquids directly affect the propagation distance of ultrasonic waves. When the liquid medium is oil, the propagation distance is shorter than that of water, and as the temperature increases, the propagation distance also shortens.

2.The height of the liquid level: The height of the liquid level is the most basic factor in determining the range. Generally, the measurement range of an ultrasonic level gauge is1-15Rice, but there are also smaller or larger range options in practical applications.

3.The shape and size of the container: The shape and size of the container also affect the measurement range of the liquid level gauge. If the container is relatively small or has a complex shape, the number of signal rebounds will increase, affecting the accuracy of the measurement.

4.The density and turbidity of liquids: Because ultrasonic waves experience energy loss when propagating turbid liquids, turbidity affects the propagation distance of ultrasonic waves, while the density of liquids affects the propagation speed of ultrasonic waves.

5.Is there gas present? The presence of gas can affect the propagation of ultrasonic waves. If there is gas above the liquid surface, it can affect the propagation of ultrasonic waves near the liquid surface, thereby affecting the measurement range of the level gauge.

In short, the measurement range of ultrasonic level gauges is influenced by multiple factors, and we need to consider these factors when choosing a level gauge in order to select a suitable instrument.
