QDR-20 is a sensor used to determine the level of various liquids and materials in vessels. Specifically, it is an ultrasonic-based non-contact level measurement system. It works on the principle of pulse-echo or time-of-flight (ToF) method. The system uses an ultrasonic transducer, such as a piezoelectric crystal, as an energy source and as a receiver. The pulse of ultrasonic energy is emitted from the transducer into the liquid and material level, and then it is reflected back as an echo that is received by the same transducer.

The time-of-flight method employed in QDR-20 measurement is based on the travel time of the ultrasonic wave in the medium. The speed of the sound wave in the material is determined by the material properties. On the basis of this information, the system calculates the time taken for the sound wave to travel from the transducer to the surface of the material being measured. This measured time is then converted to the distance from the transducer to the surface of the material in terms of applied pressure or level.

Since the QDR-20 system employs an ultrasonic pulse-echo system, it is able to accurately measure the level of liquids and materials in pressurized vessels or tanks with depths from a fraction of an inch to several feet. It also has the advantage of being able to measure the level of materials in low pressure systems where the traditional level measurement techniques are no longer usable. This in turn allows for the use of QDR-20 in a variety of applications, such as in the food and beverage industry, chemical process plants, gas production facilities, and wastewater treatment plants.

The QDR-20 system use non-invasive technology, which ensures that the level sensors do not come into contact with the materials being measured, thus eliminating the need for regular system maintenance and ensuring that no contamination of the measured material occurs. Additionally, the QDR-20 system requires minimal installation and setup time, making it ideal for a wide range of industrial applications. The system can be integrated easily with other equipment, making it easy to expand and update existing sensing systems. Furthermore, the accuracy of this system is equivalent to that of other level measurement systems. This, coupled with its ease of use, durability, and affordability makes it a popular choice among industrial users.

The QDR-20 system is widely used in a variety of industries and applications, from food and beverage production to chemical processing, water treatment, and gas production. To sum it up, the QDR-20 system is a highly effective and reliable ultrasonic-based level measurement system that is easy to install and requires minimal maintenance. It also provides accurate level measurements with an accuracy that is equivalent to that of the other advanced level measuring systems.
