Method for diagnosing field detection compliance and precision of water meters of self-provided water intaking users in riverway

The invention discloses a method suitable for on-site detection compliance and precision diagnosis of water meters of self-provided water intaking users in a river channel, which comprises the following steps: acquiring environmental condition parameters of an on-site detected water meter, and controlling the detected water meter and a standard water meter to be in the same working environmental condition; carrying out one-time synchronous data acquisition on the tested water meter and the standard water meter, carrying out first consistency check, judging whether the reading of the tested water meter is normal or not, and judging whether the necessity of second consistency check is needed or not; carrying out secondary synchronous data acquisition on the detected water meter and the standard water meter under the condition that the first reading is abnormal, carrying out secondary consistency inspection, judging whether the reading of the detected water meter is normal or not, and giving a detection result w
