Magnetic sensing electronic water meter and measuring method thereof

Abstract

The invention discloses a magnetic sensing electronic water meter. The water meter comprises a meter body, a water passage, impellers, circular magnetic steel, a magnetic sensor, a data processor, a circuit board, an electrical box, a display device and a power module. First, a system is initialized; when water enters from the water passage, the impellers rotate to drive the circular magnetic steel on a rotating shaft to rotate, the magnetic sensor outputs a voltage signal to the data processor after detects a magnetic signal, the data processor converts the voltage signal into readable data after collecting and calculating the the voltage signal, and the readable data is displayed in the display device. According to the magnetic sensing electronic water meter and a measuring method, the authenticity, accuracy and reliability of an electronic water meter measurement method are improved, the magnetic sensor and a water meter base meter are organically combined to prolong the service life of the water meter, and the water meter is simple in structure, convenient to use and practical.

Description

technical field [0001] The invention belongs to the field of water meters and intelligent meter reading, and in particular relates to a magnetic transmission electronic water meter and a measurement method thereof. Background technique [0002] As we all know, there are many methods for measuring water flow, and the corresponding test devices are also various. For example, a mechanical transmission water meter is used to display the water consumption with a pointer or a character wheel counting structure. Due to the use of a large number of transmission gears, the long-term The rotation and wear of time greatly affects the accuracy of measurement. When the flow is small, the kinetic energy of the water flow is difficult to overcome the inertia and resistance of the mechanical parts of the water meter, resulting in non-counting or inaccurate counting of the flow rate. Smart water meters install sensing elements on the pointer of the reading plate of the water meter to convert...

[0002] As we all know, there are many methods for measuring water flow, and the corresponding test devices are also various. For example, a mechanical transmission water meter is used to display the water consumption with a pointer or a character wheel counting structure. Due to the use of a large number of transmission gears, the long-term The rotation and wear of time greatly affects the accuracy of measurement. When the flow is small, the kinetic energy of the water flow is difficult to overcome the inertia and resistance of the mechanical parts of the water meter, resulting in non-counting or inaccurate counting of the flow rate.

The intelligent water meter installs sensing elements on the pointer of the reading plate of the water meter, converts the mechanical reading into an electrical signal, and then detects, calculates, and transmits it. It does not break away from the traditional model of the original mechanical water meter, nor can it fundamentally solve the problem
