Embodiment Construction

[0046] The present application will be further described in detail below with reference to the accompanying drawings.

[0047] Capacitive proximity switches are usually measured with one plate that makes up the capacitor, while the other plate is the housing of the switch. This enclosure is usually grounded or connected to the device's enclosure during measurements. When an object moves to the proximity switch, no matter whether it is a conductor or not, due to its proximity, the dielectric constant of the capacitor will always change, so that the capacitance will change, and the state of the circuit connected to the measuring head will also occur. Variety. The objects detected by this proximity switch are not limited to conductors, but liquids or powders that can be insulated.

[0048] The embodiment of the present application discloses a water meter for liquid level detection. refer to figure 1 and figure 2 The liquid level detection water meter includes a water meter ...

Abstract

The application relates to a liquid level detection water meter and a detection method. The liquid level detection water meter comprises a water meter housing, a capacitive sensor, a processing module, a first control module, an integral capacitance module and a second control module; a baffle plate is arranged in the water meter housing , the baffle plate divides the water meter shell into a flow cavity and a metering cavity, and the capacitive sensor is arranged on the side of the baffle plate away from the flow cavity; the processing module outputs the first signal and the second signal; the first control module receives the first signal and Control the capacitance sensor to charge or discharge; the integrating capacitance module is electrically connected with the processing module, and the integrating capacitance module outputs a voltage signal to the signal receiving end; the second control module receives the voltage signal of the capacitance sensor and the second signal of the processing module and controls the integrating capacitance The module is charged or discharged. The present application has the effect of being able to judge in time whether there is a water body approaching in the water meter without contacting the water body.

Description

technical field [0001] The present application relates to the technical field of detection devices, and in particular, to a liquid level detection water meter and a detection method. Background technique [0002] In recent years, with the development of smart life, more and more smart life platforms have improved people's quality of life. For example, in the application scenario of smart water supply, intelligent remote automatic meter reading control technology is vigorously advocated and applied. However, sometimes the displayed value of the water meter does not change for a long time. Therefore, it is necessary to detect whether there is water in the water meter to determine whether the displayed value of the water meter does not change for a long time because the user does not use water, or the water supply pipeline where the water meter is located is blocked due to the failure of remote closing and water supply. [0003] At present, when the pipeline is cut off, it is ...
