Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0020] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0021] In addition, it should be noted that the orientations or positional relationships indicated by left, right, up, and down in the embodiments of the present invention are based on the orientations or positional relatio...

The invention provides a water meter device. The device comprises a water pipe and a water meter assembly used for monitoring the flow of water flow in the water pipe. The water meter assembly comprises a box body, an outer cover which is hinged to the box body and can seal the opening, a circuit board arranged in the box body, a chip arranged on the circuit board and electrically connected with the circuit board, a graphene flow sensor which is electrically connected with the circuit board and extends into the water pipe, a display screen arranged in the box body and electrically connected with the circuit board, and a cover opening switch which is arranged on the outer cover and electrically connected with the circuit board, wherein and the box body is fixed to the water pipe and is provided with an opening. According to the water meter device, the water pipe is provided with a box body loading circuit board, the chip and the display screen, and is electrically connected with the circuit board through the graphene flow sensor extending into the water pipe, so that it is guaranteed that the flow of the water flow in the water pipe is accurately measured, the daily freezing water quantity can be calculated by a user, and the water meter device is low in cost and low in power consumption.
Description
technical field [0001] The invention relates to the technical field of household water meters, and more specifically relates to a water meter device. Background technique [0002] my country is a country seriously short of water resources. More than 550 cities are short of water. There is no objection to the tiered water price as a national policy, but the implementation of the tiered water price must obtain the user's daily frozen water amount. As we all know, the current household water meters are dominated by mechanical water meters, which are low in cost, poor in accuracy, and have no ability to freeze water consumption. It is necessary to install a character wheel direct reading device to meet the relevant requirements, resulting in high cost and poor reliability. [0003] At present, the fully electronic water meters on the market that are easy to realize the frozen water volume on the settlement day mainly include ultrasonic water meters and electromagnetic water mete...
