Abstract
Apparatus for measuring fluid flow comprising a tubular body (4) within which is supported an insert (5) having on its outer surface a helical formation of crests (6) and troughs (7). Between the body (4) and the insert (5) there is a fluid flow path (8). A transducer (20) detects fluctuations in fluid flow characteristics in the path (8), and a resultant signal is transmitted via amplifier (21), filter (22) and frequency counter (23) to a display (24) calibrated in terms of rate of fluid flow along the path (8).
Claims16
Apparatus for measuring fluid flow comprising a tubular body, means defining a fluid flow path, a member within said tubular body formed of crest and trough formations disposed along said path such that the flow of fluid is between the outer surface of said member and the internal surface of said tubular body and produces a signal which is dependent upon the fluid flow, means for detecting said signal, and means for converting the detected signal to provide a measurement of the fluid flow.
