Fluid flowmeter has measured fluid flow directed tangentially across turbine wheel blades between symmetrically angled entry and exit channels coupled to central entry and exit connections

摘要

The flowmeter has a turbine wheel contained in a measuring chamber (11) within the meter housing (10), the wall (12) of the measuring chamber having an entry connection (15) communicating with an entry channel (20) and an exit connection (16) communicating with an exit channel (30). The entry and exit points lie along the central axis (y-y) of the housing, the entry and exit channels angled so that their ends are aligned with one another in the tangential direction of the turbine wheel, with a straight wall section (22) between them.
