This invention relates to the field of metering instrument data acquisition technology, specifically to an anti-interference coded reading sensor and reading method for water meters. The method involves mapping the resistance value of each code disk area to three mechanical connection states, corresponding to different operating conditions of the water meter's discontinuous gear mechanism. The width of the dividing line between the digits 9 and 0 on the code disk is greater than the width of the dividing lines between other digits. This results in a shorter time window and later triggering of the brush when passing through this critical zone, providing a clear timing distinction window for the carry-over action of the higher-order digits and effectively avoiding misjudgments when multiple digits carry over simultaneously. During reading, the resistance corresponding to different digits is measured, and a software algorithm based on gear rules and water flow constraints is used for state verification, eliminating illegal reading combinations caused by mechanical intermittents or water hammer reversal. This solves the problem of code skipping and errors in the carry-over critical zone of existing direct-reading sensors, improving the reliability and accuracy of electronic readings.
