Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water meter calibration, in particular to a water meter calibration system. BACKGROUND

[0002] The water meter is an instrument for measuring water flow, and the water meter needs to be detected and calibrated for measurement accuracy by a water meter calibration system before leaving the factory. The existing water meter calibration system usually includes a water tank, a detection tank, a connecting device and the like. The connecting device usually includes a first connecting pipe and a second connecting pipe. The water outlet of the water tank is connected with the first connecting pipe, the water inlet of the detection tank is connected with the second connecting pipe, and the water outlet of the detection tank is connected with the water inlet of the water tank. An electronic scale is arranged in the detection tank. The water meter to be calibrated is installed on a detection pipe. During detection and calibration, the two ends of the detection pipe are connected with the first connecting pipe and the second connecting pipe respectively. The water in the water tank flows through the detection pipe, i.e. the water meter, and further flows through the second connecting pipe to the electronic scale of the detection tank. The measurement accuracy of the water meter is detected and calibrated by comparing the weight of the water detected by the electronic scale per unit time.

[0003] However, the above-mentioned water meter calibration system has the following technical problems: the diameters of the first connecting pipe and the second connecting pipe of the connecting device are fixed, so that the first connecting pipe and the second connecting pipe can only adapt to a detection pipe with the same diameter size.

For example, the detection and calibration of a water meter with a large range usually corresponds to a detection pipe with a large diameter. The above-mentioned connecting device cannot well adapt to detection pipes with different diameters, thereby affecting the application range of the water meter calibration system. SUMMARY

When the connecting device needs to be connected with detection pipes of different caliber sizes, in the process of rotating and adjusting the first connecting pipe 5 and the second connecting pipe, when the signal emitted by the signal transmitter can be just received by the signal receiver, it indicates that the positions of the two groups of first connecting pipes 5 and second connecting pipes have corresponded to and aligned with each other at this time, and at this time, the controller controls the prompting device to prompt the user to stop rotating the first connecting pipe and / or the second connecting pipe; at the same time, when the above-mentioned first rotating device and second rotating device adopt automatic rotating devices such as motors, when the positions of the two groups of first connecting pipes 5 and second connecting pipes have corresponded to and aligned with each other, the controller can also control the first rotating device and the second rotating device to stop rotating.
