Description

Technical Field

[0001] The utility model relates to an ultrasonic liquid level meter, in particular to an auxiliary tooling used for the ultrasonic liquid level meter to detect liquid level. Background Art

[0002] The ultrasonic level meter determines the liquid level by emitting ultrasonic pulses and receiving their reflected signals. Its core component is the ultrasonic sensor, which can both emit and receive reflected ultrasonic waves. During the measurement process, the ultrasonic pulse is emitted by the sensor, and the sound wave is reflected by the liquid surface and received by the same sensor. The sound wave is converted into an electrical signal by the piezoelectric crystal, and the time between the emission and reception of the sound wave is used to calculate the distance from the sensor to the surface of the liquid being measured. The propagation time of the sound wave is proportional to the distance from the emission of the sound wave to the surface of the object, so the distance can be calculated by measuring the time difference.

[0003] Ultrasonic level meters use a non-contact measurement method. The probe does not need to be in direct contact with the liquid, so it is not affected by the liquid's physical properties such as viscosity and density. At the same time, ultrasonic level meters have high measurement accuracy and stability and can provide accurate liquid level readings. It accurately measures the time interval from ultrasonic emission to reception, combined with the known speed of sound, to calculate the distance from the liquid surface to the transducer, thereby achieving liquid level height measurement.

[0004] In the past, ultrasonic level meters were used to directly detect the liquid level when there was a lot of foam on the liquid surface. However, when a large amount of foam existed on the liquid surface, the liquid level feedback from the level meter was often inaccurate. At the same time, when the tank needed to be replenished in time, the level meter could not accurately feedback the actual liquid level. Utility Model Content
