Title:
DEVICE AND METHOD OF MEASURING PIPE JOINT
Document Type and Number:
Japanese Patent JPS5910801
Kind Code:
A
Abstract:
A hand-held, digital display instrument 26 which, when activated, automatically measures, displays and records the lengths of tubular goods, such as joints of tubing or casing. Two separate hand-held units 26, 30 are positioned at opposite ends of the joint 12 of pipe to be measured or tallied. One of the units 26 automatically transmits from an antenna arrangement a distance measuring signal 28, computes the length I1 of the joint, displays the length in feet and tenths on a digital readout, records the length on a print-out tape, and incorporates a cumulative memory register. The other unit 30, positioned at the opposite end 24 of the joint to be tallied, reflects the transmitted distance measuring signal back to the first unit 26 for the length computation. Joint lengths are tallied, one after another, and the total lengths are sequentially, automatically calculated while the cumulative totals are displayed and recorded.
