Abstract
A device for measuring fluid flow rates has a body defining a conduit for the fluid, the body having selectable first and second configurations, in the first configuration the body presents a first constriction in the conduit for measuring a first range of fluid flow rates, and in a second configuration the body presents a second construction in the conduit for measuring a second range of fluid flow rates, the second constriction being narrower than the first constriction, the body being arranged for operative connection to parts for determining the pressure difference between each constriction.
