Abstract

The invention discloses a signaling ring with forward and reverse Hall measurement for a water meter. The signaling ring with forward and reverse Hall measurement for the water meter comprises a shell. The shell is provided with a pipeline, a rotating shaft is installed in the shell, an impeller is installed on the rotating shaft, a magnetic ring is installed at the top of the rotating shaft, a magnet is installed on the magnetic ring, and Hall elements is installed at the position, located at one side of the magnetic ring, of the top of the shell. According to the signaling ring with forwardand reverse Hall measurement for the water meter, the conduction and disconnection of the Hall elements are determined by utilizing the polarity, so that the Gaussian value of the magnet is increased,and the reliability of the product is ensured; and the magnet is used, the structure is simple, and the direction of magnetic lines is changed along the circumferential movement, so that the Hall elements are turned on and off, and the two Hall elements are turned on simultaneously, so that the forward and reverse rotation of the water meter is identified, and the metering accuracy of the water meter is further solved.

Description

【Technical field】 [0001] The invention relates to the technical field of fluid metering equipment, in particular to a water meter with a sending circle for forward and reverse Hall metering. 【Background technique】 [0002] The signal acquisition of smart water meters has always been a technical problem that many manufacturers in this industry have to solve. The price is cheap, the batch is stable and reliable, and it has a long service life. It is the goal of our industry. [0003] The sensor (sending circle) of the water meter, the reed switch pulse sending circle: the reed switch is also a kind of pulse acquisition method, because of its low cost, few fault points, and the number of pull-in times is more than 1 million times. There are many applications, but because it is a mechanical test pull-in method after all, there is a phenomenon of vibration. At the same time, because of the large size, the structure is installed on the movement of the water meter, it is difficult ...
