Turbine for axial or tangential liquid flow meters

摘要

The turbine has a hollow body, through which the liquid flows, and a rotor fitted with a blade (3) designed to turn freely in the body at a speed proportional to the flow of the liquid. The turbine has at least a sensor designed to produce an electrical signal which is a function of the value of the physical magnitude characteristic of the rotation of the rotor. The rotor has a hub (1) having a single cavity (2) limited by the exterior wall of the hub and closed in a sealed way so that the hub forms a float in the liquid current.
