Problems solved by technology

In the actual production process of the above method, the performance of the water meter is affected by factors such as equipment conditions and human factors, and because the series detection device cannot adjust the water meter in real time, the unqualified water meter must be returned for readjustment, resulting in very low production efficiency
In recent years, various automatic meter calibration devices have also appeared. Although it can reduce human error to a certain extent, it has not been able to solve the problem of rapid testing of all flow points on the same detection device.

Abstract

The invention discloses a full-flow-point rapid detection device for a water meter. The full-flow-point rapid detection device comprises an embedded controller and a detection system, wherein in the detection system, a standard water meter and a calibrated water meter are arranged in sequence on a pipeline between a water inlet tube and a water outlet tube; color mark sensors are arranged above the standard water meter and the calibrated water meter respectively; an electromagnetic valve I is arranged on the water inlet tube; a flow point switching electromagnetic valve II is arranged on the water outlet tube; and the embedded controller comprises a frequency multiplication module for performing frequency multiplication on pulses input by using the color mark sensors, a flow point control module which can be used for realizing automatic switch of each flow point, a keyboard module which can be used for receiving input parameters and commands of operating personnel, an LCD (Liquid Crystal Display) module which can be used for displaying current testing information, and a main control module which can be used for processing receiving and transmitting commands and computing errors of the calibrated water meter. According to the full-flow-point rapid detection device, the sampling accuracy is effectively increased, and the calibrated water meter can be used for finishing testing of all flow points in a short period of time on the same device, so that the water meter detection accuracy and production efficiency are increased greatly.

Description

technical field [0001] The invention relates to a water meter error detection technology, in particular to a fast detection device for the full flow point of the water meter. Background technique [0002] At present, in the production process of water meters, especially in the production process of large quantities of water meters, the test of each flow point is mainly carried out by detection devices with different functions, such as: volumetric water meter detection devices or computer detection devices are often used for large flow and nominal flow , while the boundary flow and small flow often use a series detection device to realize the detection of the error of each flow point of the water meter. In the above method, the performance of the water meter is affected by factors such as equipment working conditions and human factors in the actual production process, and because the serial detection device cannot adjust the water meter in real time, unqualified water meters...
