Abstract

Continuous flowmeter for well drilling. Body can be lowered into a borehole on a cable, and has a central tubular part which defines a measuring channel, in which is a propeller driven by the fluid flowing in the canal. The rotation speed of the propeller represents the fluid flow speed. The channel is symmetrically shaped relative to the propeller's plane of rotation, and communicates with the outside of the body via divergent passages which are symmetrical relative to the plane and inclined to the long axis of the body at a low enough angle for the fluid flow not to be perturbed.
