Abstract
A hand-held OCTG length measuring apparatus has hollow upper and lower bodies, a hand grip extending generally downward from the hollow upper body near the first end and including a source trigger, and a sensor housing extending generally downward from the hollow upper body. The sensor housing encloses a TOF source operatively connected to the source trigger. The hollow lower body shaped to include a frontal cavity positioned generally under the source housing, the frontal cavity having attached thereto a pipe end alignment bracket. The upper hollow body and the lower hollow body connected at a lower end of the hand grip and at a lower end of the sensor housing. The apparatus employs a minimum 40,000 lux laser (at 18 to 25 feet) and a polarized, diamond-grade reflector, to afford reliable, repeatable OCTG length measurements.
