Abstract
The present invention provides an improved insertion-type fluid flowmeter for measuring the flow rate of a fluid flowing through a conduit, wherein the flowmeter incorporates a strut-mounted rotor having just one or two blades such that it can rotate through a circular area of diameter substantially larger than the maximum dimension of an opening in the conduit wall through which the strut extends. This minimizes the size of the opening, which simplifies its sealing. In addition, the support and the strut are configured such that the strut is releasably secured to the support by a snap fit, to facilitate a convenient replacement of the strut and attached rotor as the need might arise. The flowmeter further incorporates a special set of ring-shaped spacers, to facilitate a convenient adjustment of the distance by which the strut projects into the conduit.
