Description
Technical Field
The utility model relates to an intelligence water gauge field, specifically speaking involve an adopt remote no magnetism sampling's positive displacement water gauge.
Background
Water meters, as a kind of measuring instrument, are used for measuring the cumulative flow rate of water, and are generally classified into positive displacement water meters and water meters in the market, in which the volume of water flowing through a tap water pipe is calculated by using the direct mechanical movement process of a movable wall volume measuring chamber or the action of the flow rate of water on a wing wheel. At present, a reed switch and a Hall element are mostly adopted in a flow acquisition mode in a water meter, but both the reed switch and the Hall element have obvious defects, once the reed switch fails, the failure detection is quite difficult, and the reed switch is not suitable for product design with high requirement on errors due to large errors, has short service life and is not suitable for production; hall elements are susceptible to interference from magnetic and electric fields when operating.
Generally, most nonmagnetic sampling water meters are provided with a circular pointer on a dial plate of a water meter base meter, the circular pointer is made of plastic and metal, a sampling module on a control circuit module is matched with the circular pointer on the dial plate of the water meter base meter to complete nonmagnetic sampling of the flow of the water meter, and most water meter manufacturers can process the thickness of a nonmagnetic sampling part of the dial plate glass due to the fact that the nonmagnetic sampling limits the distance between the sampling module and the circular pointer on the dial plate.
