Abstract
The invention is related to a device for measuring the flowrate of fluid through a well. The device according to the invention comprises an upper portion adapted for connection with a cable, two elongated side members, generally parallel to and spaced from each other, secured to the upper portion, a vortex generating assembly comprising at least one obstacle secured between said side members transversely of their longitudinal direcition, said side members having, at least in the region of said assembly, facing walls which are substantially planar, and a transducer responsive to the occurrence of vortices generated by said assembly, said transducer producing a signal indicative of said flowrate.
