Which working conditions are not suitable for the use of ultrasonic level gauges?
Ultrasonic level gauges can be directly used to query the liquid level height of various media in containers. The ultrasonic level gauge is suitable for liquid level indication in industrial fields such as petroleum and chemical engineering. It has a simple structure, intuitive and clear query, does not clog or leak, is convenient to install and easy to maintain.
Ultrasonic level gauges are not suitable for use in the following scenarios
1. Not suitable for operation underwater or in pressure vessels;
2. The sensing accuracy is affected by soft materials. Objects covered in soft fabrics will absorb more sound waves, making it difficult for the sensor to detect the target.
3. It cannot operate in a vacuum. Because ultrasonic sensors need to operate based on movement and stillness, and there is no air in a vacuum to convey movement and stillness, they are completely unable to operate in a vacuum.
4. Slender objects under test have difficulty reflecting sound waves. If the object is relatively slender and cannot reflect enough sound waves back to the ultrasonic sensor, it will affect the measurement of the ultrasonic level gauge.
5. Some specific shapes are difficult to capture reflected waves. Some objects, due to their special shapes or positions, cause the ultrasonic waves that bounce off the objects to deviate from the measurement surface.
A temperature change of 5 to 10 degrees or more will affect the sensing accuracy. However, as more and more manufacturers apply temperature compensation to their products, calibration can be carried out based on changes in temperature, voltage, etc. when the sensor is activated or before each range reading.
