Analysis On Which Occasions Ultrasonic Liquid Level Gauge Is Not Suitable For

Ultrasonic liquid level gauge is a non-contact, cost-effective measuring instrument that performs level measurement based on the principle of acoustic wave emission. It is widely used in petroleum, mining, electric power, chemical industry, environmental protection and other industries. However, not all situations are suitable for using ultrasonic continuous level sensors. The following are some situations where ultrasonic liquid level meters are not suitable for use:

1. In a vacuum environment: ultrasonic liquid level gauge requires sound waves to propagate through the medium for measurement, and cannot accurately measure in a vacuum environment.

2. Occasions with large range and high precision requirements: Since ultrasonic waves will attenuate during propagation, the actual measurement range is smaller and the accuracy is slightly lower, so it is not suitable for use in occasions with large range and high precision requirements.

3. High temperature and high pressure environment: The transducer material of ultrasonic liquid level gauge is usually piezoelectric ceramics and plastic shell, which cannot be used in high temperature and high pressure environment, and the withstand temperature can generally only reach 80°C.

4. Occasions with frequent temperature changes: The distance value measured by the ultrasonic continuous level sensor is obtained by multiplying time by the speed of sound, and the speed of sound will change with temperature changes, resulting in inaccurate data. Therefore, ultrasonic fluid is not suitable for use in situations with frequent temperature changes. bit meter.

Understanding the situations where ultrasonic liquid level gauge is not suitable will help you to correctly select a suitable liquid level gauge for accurate liquid level measurement and ensure the stability and reliability of the industrial production process.
