Abstract
The utility model belongs to the product detection devices, and in particular relates to an automatic detection device using water meter measuring characteristics of a visual device. The detection device comprises an industrial personal computer, a set of visual device, two rows of serial tables, four glass floating flowmeters, three standard metering cylinders, ten manual valves and seven electromagnetic valves sequentially connected, wherein each standard metering cylinder is provided with a probe in a predetermined water level. When the water yield reaches the predetermined position, a water level relay actuates to precisely measure the water yield flowing through the tested water meter. At the beginning of test and after test at every flow point of the water meter, the dial plate of the water meter is photographed, and the water yield measured by the tested water meter is obtained by image identification for an appointer area and an indicating wheel area in each test state. The measurement error of the tested water meter at each measurement point is detected by comparing with corresponding standard water yield after calculation. Error information is stored in a corresponding information list.
