Abstract:
     The diameter measuring gauge consists of angled arms, rule body, moveable rule, digital meter and handle. It measures diameter of a circular object by means of three points contacting with the object, and the three points includes two points on the angled arms and the tip of moveable rule. The diameter value measured is read out on the moveable rule or digital meter. For the measurement of trunks and pipes, it is simple, fast and convenient. By connecting it to a computer, diameter measurement automation may be realized.
