Description

Technical Field

[0001] This application relates to the field of meter connection tube measurement, and in particular to measuring devices, methods, media, terminals and systems compatible with various meter connection tubes. Background Technology

[0002] A meter is a gas measuring instrument, such as a density relay and a pressure gauge. The connecting pipe of the meter refers to the pipe used to connect the meter. It is usually a short pipe, with one end connected to the meter and the other end connected to the gas chamber to be measured. It is made of stainless steel pipe with an outer diameter of 10mm and an inner diameter of 8mm, which is processed by cutting and bending. The shape is generally divided into straight pipe, L-shaped, Z-shaped, U-shaped and special shape, etc.

[0003] The purpose of measuring instrument connecting pipes is to ensure that the dimensions and positions of the connecting pipes conform to specifications and to guarantee the accuracy and reliability of the measuring equipment. Measuring instrument connecting pipes are typically measured using tools such as height gauges, measuring rulers, and angle measuring devices. The dimensions of the connecting pipes directly affect the assembly dimensions of the instrument and have certain tolerance requirements. Dimensions requiring strict specifications are generally determined by the positions of the two end faces of the connecting pipe. For example, straight pipes can be measured directly using calipers. However, for other types of connecting pipes, involving axial and radial dimensions, two methods are generally used for measurement. The first method uses traditional calipers or height gauges. Since radial dimensions are measured with the connecting pipe's central axis as a reference, and because the connecting pipe's surface is curved, it cannot be fixed stably, leading to larger errors when using calipers or height gauges. The second method uses a projector. The connecting pipe is placed on the measuring plane, and the projector captures the dimensions of the connecting pipe's outer edge. This method has higher accuracy but is time-consuming, complex to operate, and unsuitable for production due to the large variety and quantity of connecting pipes. Summary of the Invention
