The frame 3 above the detection assembly opening 10 is provided with a collection camera 2 (see the attached figures 1 and 2 in the specification). The acquisition camera 2 can acquire the data of the water meter reading arranged on the detection assembly port 10 during working; after the data are collected by the collecting camera 2, the data are transmitted to the PLC 1 for data processing.
A lighting lamp bar 11 is arranged on the frame 3 between the detection tube 9 and the collecting camera 2 (see the attached figures 1 and 2 in the specification). Set up daylighting lamp strip 11's aim at: so that the during operation, daylighting lamp strip 11 can provide sufficient light source for gathering camera 2 to avoid gathering camera 2 during operation, owing to lack sufficient light source, and lead to the emergence that can not accurately gather the data problem.
A water storage tank 4 is arranged on the frame 3 at one side of the detection pipe 9; the water storage tank 4 is communicated with one end of the detection pipe 9 through a water pump 6, an electromagnetic switch valve 7 and a water inlet pipe 12 (see the attached figures 1 and 2 in the specification); when the water pump 6 works, water in the water storage tank 4 can be conveyed into the detection pipe 9 through the electromagnetic switch valve 7 and the water inlet pipe 12. A manual switch valve 14 is arranged on a water inlet pipe 12 at the outlet of the water pump 6.
A weighing water tank 5 is arranged on the frame 3 below the detection tube 9 through an electronic scale; the electronic scale can detect the weight of the weighing water tank 5 and the weight of the water stored in the weighing water tank; and when the PLC works, the detected data is transmitted to the PLC 1 for data processing.
The outlet end of the detection pipe 9 is communicated with the weighing water tank 5 through a water outlet pipe 13 (see the attached figure 2 in the specification); the water output from the detection pipe 9 can flow into the weighing water tank 5 through the water outlet pipe 13.
The lower end of the weighing water tank 5 is connected with an electromagnetic water drain valve 8; the electromagnetic water escape valve 8 is communicated with an external water recovery system; after the electromagnetic drain valve 8 is opened, water in the weighing water tank 5 can be discharged to an external water recovery system through the electromagnetic drain valve 8 for recovery.
A PLC programmable controller 1 (see the attached figures 1 and 2 of the specification) is arranged on the frame 3; the PLC 1 is of a Siemens S7-200CN type.

At the moment, each acquisition camera 2 acts to transmit the acquired water meter reading V2 to the PLC 1; the electronic scale transmits the measured weight M2 to the PLC programmable controller 1.
After receiving the signals of V2 and M2, the PLC 1 calculates the error e of the water meter; water meter error e = [ V2-V1) - { (M2-M1)/ρ) }/[ M2-M1)/ρ ], wherein ρ is the density of water; if the water meter error e is larger than e1, the corresponding water meter is an unqualified product, the PLC 1 sends an alarm corresponding to the position of the detection assembly port 10, and the water meter assembled in the detection assembly port 10 is an unqualified product; otherwise, the product is qualified if no alarm is given.
