Description

Ultrasonic liquid level meter

Technical Field

The utility model relates to the technical field of ultrasonic measurement, in particular to an ultrasonic liquid level meter.

Background

The ultrasonic liquid level meter is a digital liquid level meter controlled by a microprocessor and consists of an ultrasonic transducer, a processing unit and an output unit; in the measurement, ultrasonic pulses are emitted by a sensor (transducer), sound waves are reflected by the surface of the liquid and then received by the same sensor or an ultrasonic receiver, the sound waves are converted into electric signals through a piezoelectric crystal or a magnetostrictive device, and the distance from the sensor to the surface of the measured liquid is calculated according to the time between the emission and the reception of the sound waves. Because of adopting non-contact measurement, the measured medium is almost unlimited, and can be widely used for measuring the height of various liquid and solid materials.

However, because the ultrasonic pulse emitted by the existing ultrasonic liquid level meter has a certain sound velocity, the reflected wave and the emitted wave in a section of area close to the transducer are overlapped, so that the reflected wave and the emitted wave cannot be identified, and the distance value cannot be measured. This area is referred to as a measurement blind area. In addition, when the ultrasonic liquid level meter is installed, flanges are mostly adopted for installation and fixed connection, adjustment and change are inconvenient to conduct after installation, when the liquid level is large, when the liquid level is in a measurement blind area, the ultrasonic liquid level meter is required to be installed again after being disassembled or a guide pipe is added for measurement, operation is complex, measurement accuracy can be affected, and the ultrasonic liquid level meter is easy to damage in the using process due to lack of a protection structure.
