specific Embodiment approach 1

[0017] Specific implementation mode 1: refer to Figure 1 to Figure 6 Specifically describing this embodiment, the wireless valve-controlled ultrasonic water meter described in this embodiment includes: ultrasonic base meter 1, wireless transmission circuit 1 2-1, wireless transmission circuit 2 2-2, motor 4, main circuit 5, ultrasonic wave Transducer 7, temperature sensor 8, battery one 9 and battery two 10;

[0018] There are three openings on the side wall of the ultrasonic base meter 1. The two ultrasonic radiating ends of the ultrasonic transducer 7 and the temperature measuring end of the temperature sensor 8 pass through the three openings and are located inside the ultrasonic base meter 1. Sealed, the two ultrasonic radiating ends of the ultrasonic transducer 7 face each other, and the temperature measuring end of the temperature sensor 8 is used to collect the internal water temperature of the ultrasonic base meter 1.

[0019] The ultrasonic signal output end of the ...

specific Embodiment approach 2

[0025] Embodiment 2: This embodiment further describes the wireless valve-controlled ultrasonic water meter described in Embodiment 1. In this embodiment, it further includes: a display screen 3, and the display signal output end of the main circuit 5 is connected to the display screen 3 signal input terminals.

[0026] In this embodiment, the display screen 3 is an LCD display, which can display accumulated flow, water temperature, instantaneous flow rate, valve status, arrears information, clock, address and other information.

specific Embodiment approach 3

[0027] Specific implementation mode three: refer to Figure 5 This embodiment is described in detail. This embodiment further describes the wireless valve-controlled ultrasonic water meter described in Embodiment 1. In this embodiment, the two ultrasonic waves of the ultrasonic transducer 7 and the measurement of the temperature sensor 8 The warm end seals the opening where it is located through the sealing ring 11 respectively.

[0028] The sealing ring 11 is installed at the gap position between the ball valve 6, the ultrasonic transducer 7 and the temperature sensor 8 and the ultrasonic base meter 1 to prevent the leakage of water from the ultrasonic base meter 1, as shown in the appendix. Figure 5 shown.

Abstract

The invention provides a wireless valve control ultrasonic water meter and relates to the field of water meters. The wireless valve control ultrasonic water meter aims at solving the problem that existing mechanical water meters used by residents have multiple defects. The ultrasonic time difference principle is adopted, the full-electronic water meter is manufactured from industrial-grade electronic components, and compared with the mechanical water meters, the wireless valve control ultrasonic water meter has the advantages that precision is high, reliability is good, the range ratio is large, the service life is long, no moving part is arranged, parameter setting is not needed, and the water meter can be installed at any angle. Based on the metering mode of the ultrasonic water meter, the advantages of wireless centralized collecting and valve control are added. A pair of ultrasonic transducers is applied to a flow measuring part for oppositely receiving and transmitting ultrasonic waves, the flow speed of fluid is indirectly measured by observing the fair flow and reverse flow propagation time difference of the ultrasonic waves in a medium, and the flow is calculated through the flow speed. The wireless valve control ultrasonic water meter can be widely applied to water supply metering of a running water company.

Description

technical field [0001] The invention belongs to the field of water meters, in particular to a wireless valve-controlled ultrasonic water meter. Background technique [0002] Water meters are necessary equipment for every household. At present, all households use mechanical water meters and settle fees according to the instructions of the water meters. However, there are many disputes and drawbacks that are difficult to resolve when using the existing mechanical water meters for settlement. For example: the accuracy of the thermal energy meter is reduced due to the severe wear and tear of the mechanical water meter for a long time, and the user needs to pay for maintenance several times, resulting in difficult disputes between the user and the water company; the water company staff regularly knock on the door of the user to check the water meter For flow data, the success and accuracy of meter reading are low, and the management cost of the water company is too high, which is...
