Ultrasonic external mounted liquid level gauge

External mounted ultrasonic level gaugeUltrasonic external mounted liquid level gaugeIt is an advanced instrument used to measure the height of liquid in storage tanks, tanks, and other containers. This article will delve into the principles, advantages, and precautions for using external ultrasonic level gauges from the perspectives of theoretical framework, practical suggestions, and problem-solving methods.

theoretical framework

External mounted ultrasonic level gauge measures liquid level height by sending ultrasonic signals and receiving echoes. The principle is based on the characteristic that sound waves propagate at different speeds in different media. When the ultrasonic signal encounters a liquid interface, some of the energy will be reflected back. By measuring the time difference between the emission and reception of ultrasonic waves, the height of the liquid level can be calculated.

Compared with traditional measurement methods, external ultrasonic level gauges have many advantages. Firstly, it does not require direct contact with liquids, avoiding issues of sensor damage and corrosion. Secondly, due to the lack of physical contact between the liquid and the sensor, the measurement of liquid level is not affected by factors such as surface evaporation and condensation of the liquid, ensuring the accuracy of the measurement results. In addition, the external mounted ultrasonic level gauge also has a large measurement range and high measurement accuracy, suitable for various liquid media.

Practical advice

Ultrasonic external mounted liquid level gaugeWhen choosing and using an external ultrasonic liquid level gauge, the following points need to be noted. Firstly, it is necessary to select the appropriate model based on actual needs. The characteristics of different liquid media, such as temperature, pressure, viscosity, etc., will affect the selection and installation position of level gauges, so it is necessary to choose the appropriate instrument according to the actual situation.

Secondly, when installing an external mounted ultrasonic level gauge, it should be ensured that there is no physical contact between the sensor and the measuring medium to avoid affecting the measurement results. In addition, to ensure the accuracy of the measurement, the sensor should be calibrated before measurement and regularly maintained and inspected.

Methods to solve problems

When using an external mounted ultrasonic level gauge, some common problems may be encountered. For example, due to the evaporation and condensation of the medium, liquid droplets or water films may appear on the sensor, affecting the measurement results. At this point, compressed air can be used to blow dry the droplets, or special coatings can be used to prevent the formation of a water film.

In addition, when the liquid level gauge is installed above the storage tank, the upper part of the liquid level may be affected by temperature or pressure changes and undergo changes. To solve this problem, a compensation function can be installed on the liquid level gauge to automatically correct the measured value of the liquid level based on changes in temperature and pressure.

Q&A

Q: Which liquid media is the external mounted ultrasonic level gauge suitable for?
