The invention provides a liquid level position detection device, equipment and water supply equipment. The liquid level position detection device includes: an ultrasonic transmitter, used to send an ultrasonic signal to the opening of the target container; an ultrasonic receiver, used to obtain the reflected first Echo signal; a processing unit, configured to confirm the peak corresponding to the opening of the target container in the first echo signal, compared with the second echo signal acquired any time within the previous preset time length, the target container The wave peak corresponding to the opening changes; confirm that the liquid level of the liquid in the target container reaches the opening of the target container. The embodiment of the present invention solves the technical problem of low precision of the liquid level detection technology in the prior art, and achieves the beneficial effect of accurately detecting the liquid level.
Description
technical field [0001] The embodiments of the present invention relate to the field of liquid technology, and in particular, to a liquid level position detection device, equipment and water supply equipment. Background technique [0002] The liquid level position refers to the height of the liquid level in the open container (water tank). In daily life and industrial production and operation, it is often necessary to know the position of the liquid level in the container. [0003] With the development of science and technology to this day, humans have invented countless methods of measuring the liquid level, from ancient rulers to modern floats, ultrasonic waves, reed switches, and photoelectric water level sensors. The position of the liquid level has now become a "top player" in the fields of household appliances, petrochemicals, metallurgy, electric power, pharmaceuticals, water supply and drainage, and environmental protection, and plays an important role in various sci...
