Abstract

The invention discloses a coil induction water meter with an anomaly detection function. The water meter comprises a body, wherein the body comprises a fan-shaped metal sheet and a metering and anomaly detection module located right above the fan-shaped metal sheet; the fan-shaped metal sheet is mounted in a meter panel; and the fan-shaped metal sheet and a pointer in the meter panel coaxially rotate. A method and a system solve the technical problem that a metering water meter cannot effectively identify external interference and detection coil and disc separation anomaly.

Description

technical field [0001] The invention belongs to the technical field of water meters, in particular to a coil induction water meter with abnormal detection function. Background technique [0002] At present, water meter measurement mostly adopts dry reed switch, Hall element, and Wiegand sensor, but due to the inherent mechanical characteristics, service life and vibration resistance of the dry yellow tube, the Hall element has too much current, and there are also low or low The frequency response problem of high flow rate; the Wiegand sensor has the disadvantage of large magnetic resistance, which is very easy to absorb the impeller to increase the starting flow, and the price is expensive. Therefore, the existing remote water meter adopts the principle of non-magnetic induction to convert the rotation of the mechanical watch gear or the rotation of the pointer into an electric pulse signal. [0003] Chinese patent CN201410305843.2 discloses an upsampling separation non-mag...
