In the industrial field, the application of ultrasonic liquid level measurement technology

Level measurement breadth and immunity to interference. Liquid level measurement data is an important parameter for production and process control. The total amount of liquid in the reservoir is managed and controlled by level measurement.

In the late period, due to the small scale of production in the industrial field, mechanical measurement methods were mainly used for liquid level measurement. However, with the expansion of the production scale of many industrial automated production systems, real-time monitoring of the liquid level of the system is required.

Ultrasonic waves have the advantages of strong directivity, low energy consumption, and no direct contact with the measured object, and have been widely used in liquid level measurement. Now let us take a closer look at the related principles and applications of ultrasonic liquid level measurement.

level measuring principle

Under microprocessor control, the ultrasonic liquid level sensor emits and receives ultrasonic waves. When ultrasonic waves propagate in the air and encounter obstacles (including water and other liquids), they will produce obvious reflections. Ultrasonic waves can not only measure distance and speed, but also liquid level and material level. Measures the time it takes for ultrasonic waves to travel back and forth from the liquid level gauge to the liquid level. The distance from the liquid level gauge to the liquid surface can be obtained through the known speed of sound, and then the liquid level height can be obtained based on the total height of the liquid level gauge. It can be seen that ultrasound has the advantages of high sensitivity, long life, and long measurement distance. However, since the ultrasonic liquid level meter is based on the principle of sound reflection, there should be no obstacles under the action of sound waves. Obstacles can affect ultrasonic transmission, causing signal loss. Not recommended for use in absorbent environments such as foam.

In recent years, ultrasonic liquid level sensors have been widely used as liquid level measuring instruments. Adopt non-contact measurement method with medium. It has the characteristics of easy installation, low failure rate, convenient maintenance, high precision, and is not affected by the medium. It has wide adaptability. The LUT-20 series ultrasonic liquid level meter is an ultrasonic liquid level sensor provided to various environmental protection industries. It involves remote emission measurement of solar ultrasonic sensors and sends detection data to a centralized management system through satellite and wireless communications. Not only that, the LUT-20 series ultrasonic level gauge can detect a maximum distance of 50 feet (15.2 meters). Like all tough sensors, their durability and ease of use make them suitable for harsh industrial environments. The LUT-20 series ultrasonic level gauge is completely waterproof, corrosion-resistant, impact-resistant and tough. They are also fully configurable with SentxView software. Additionally, the LUT-20 Series Ultrasonic Level Gauge is available in three different housings, each with an RS-232 or RS-485 serial interface. Ultrasonic level sensors with communication will provide an efficient means of communication for your automation. These 9-wire sensors allow up to 6 simultaneous serial, analog and or switching outputs. These critical sensors are used in remote applications and harsh factory environments around the world. Support PC using senixview software, which can configure sensor interface, time parameters, filters and modes. Save costs and reduce the use cost of programmable logic controllers, delay circuits and delay relays.
