Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid level meters, in particular to an ultrasonic liquid level meter. Background Art
[0002] Ultrasonic level meter is a digital level meter controlled by a microprocessor, which consists of three parts: ultrasonic transducer, processing unit, and output unit. During measurement, ultrasonic pulses are emitted by the sensor (transducer), and the sound waves are reflected by the liquid surface and received by the same sensor or ultrasonic receiver. They are converted into electrical signals through piezoelectric crystals or magnetostrictive devices, and the distance from the sensor to the surface of the measured liquid is calculated by the time between the emission and reception of the sound waves. Due to the use of non-contact measurement, the measured medium is almost unlimited, and it can be widely used to measure the height of various liquids and solid materials.
[0003] The ultrasonic level meter sends out ultrasonic pulses through the probe. When the ultrasonic pulses encounter the surface of the object to be measured, they will be reflected back. The reflected ultrasonic pulses are received by the transducer, which converts the ultrasonic pulse signals into electrical signals. After passing through the data processing system, the distance the sound waves are transmitted is obtained, and then the height of the liquid level is obtained.
[0004] However, the ultrasonic pulses emitted by the existing ultrasonic level meter have a certain sound velocity, so that the reflected waves in a relatively close area overlap with the transmitted waves and cannot be identified, forming a measurement blind spot. In addition, most ultrasonic level meters are installed with flanges, which are not easy to adjust after installation. When the liquid level is high and in the measurement blind spot, the ultrasonic level meter needs to be disassembled and reinstalled or a measuring tube needs to be added for measurement, which is not only complicated to operate, but also affects the accuracy of the measurement. Therefore, those skilled in the art provide an ultrasonic level meter to solve the problems raised in the above background technology. Utility Model Content
