Zusammenfassung: | The invention discloses a pipe length measuring instrument and method. The pipe length measuring instrument comprises a measuring tape and a drawing head connected with one end of the measuring tape, and further comprises a measuring adapter sleeved at the head end of a pipe to be measured; the measuring adapter is funnel-shaped and is provided with a through hole on the side wall; one end, connected with the drawing head, of the measuring tape extends into the pipe to be measured via the through hole; the head end of the pipe to be measured is connected with a gas source or a water source; and a clamp for fixing the drawing head is arranged at the tail end of the pipe to be measured. The traditional manual measuring method or other out-of-pipe measuring method has the disadvantages of poor operability, high labor strength, high environment influence, low measurement accuracy and low working efficiency, whereas the pipe length measuring instrument for directly reading the measurement result during pipe length measurement has the advantages of measurement accuracy, small error, high precision, simplicity in operation, high efficiency and the like. |
