Problems solved by technology
Such a detection device and the method for detecting a water meter using the detection device usually have inaccurate control, resulting in a large time difference between the display value of the water meter to be tested and the display value of the detection device.
Furthermore, due to the low resolution of the water meter and certain errors in the displayed value, the measurement error will inevitably bring about a very large impact, so the measurement characteristics of the water meter to be tested are wrongly evaluated.

The invention provides a detection device for the metrological characteristics of a water meter and a detection method for using the same, which belong to the technical field of measurement, and are used for solving the problem of incorrect evaluation of the metrological characteristics of a water meter to be detected caused by the conventional detection device and the conventional method for detecting the water meter with the detection device. The detection device for the metrological characteristics of the water meter comprises a frame, a water supplying mechanism, an electromagnetic valve I, a water storing tank, a controller, a host, a fixing structure, a flow adjusting mechanism, a metering mechanism and a handheld meter reading mechanism. The method for detecting the metrological characteristics of the water meter by using the detection device comprises the following steps of clamping; introducing water, and exhausting; entering an initial value; detecting and entering an accumulated value; and calculating. The detection device for the metrological characteristics of the water meter has the advantages of compact structure and consistence with the national and international standard requirements. The detection method has the advantages of reasonable steps, accurate detection, capability of accurately obtaining the metering error of the water meter to be detected and high calculation speed. The metrological characteristics of the water meter to be detected are improved after the water meter is detected and adjusted with the detection method.
Description
technical field [0001] The invention belongs to the technical field of measurement, and relates to a detection device, in particular to a measurement characteristic detection device of a water meter. [0002] The present invention also relates to a detection method, in particular to a method for detecting metering characteristics of a water meter by using the above-mentioned detection device. Background technique [0003] The water meter is a flow meter that uses the direct mechanical motion process of the movable wall volume measurement chamber or the action of the water flow velocity on the wing wheel to calculate the flow volume of the water flow through the tap water pipe. [0004] At present, there are many types of water meters. For example, according to the measurement principle, it can be divided into speed type water meter and volume type water meter; according to the indication form of the counter, it can be divided into analog type, digital type and analog digita...
