Abstract: A method and tool for alignment of a vortex meter with pipe flanges having raised faces on the side engaged by the meter, the tool comprising a round cylinder having an eccentric hole longitudinally therethrough for rotating the tool to touch raised spaces on the flanges whereby the flanges may be aligned, and the method comprising placing two such tools which are slightly longer than the dimension of the meter body, each having an eccentric hole longitudinally therethrough, passing a bolt through the holes in the flanges and longitudinally through the tool, rotating the tools until they touch the raised faces, and placing the meter body and any required gaskets between the flanges until it rests on the tools, after which the bolts are tightened through the other holes in the flanges as well as tightening the bolts through the tools.

Abstract: A vortex flow meter for increasing the frequency of vortex shedding to improve the sensitivity of the meter in which the meter body includes a plurality, preferably two, bluff bodies positioned perpendicular to the fluid flow in the meter body. Each such bluff body has an associated sensor downstream of the flow. The spacing between the bluff bodies and between each of the outer bluff bodies and the wall of the meter body is optimized to cause the strongest vortex generation.

Abstract: A well pipe spinner includes two body parts carrying rollers and mounted by two pivotal connections for swinging movement between a closed position in which the rollers grip and drive a well pipe and an open position releasing the pipe. A structure extends between and interconnects the two pivotal connections in a relation permitting relative adjustment of their pivotal axes toward and away from one another for gripping different sizes of pipe. The tool is supported by a structure which is adapted to be suspended from a line or other element and which suspends the two body parts and pivotal connections at essentially the locations of the two pivotal axes.
