ABSTRACT:
A fluid flow rate meter, in particular a liquid flow rate meter, such as a fuel consumption meter for a motor vehicle. The meter comprises a housing to be mounted in a conduit. The housing has an axial passageway, and a liquid directing member in the form of an insert fills up the passage opening, which insert has at least one helical channel along its circumference. A rotor has a central shaft journalled with limited axial clearance on the downstream side of said insert in a cavity provided for the purpose in the downstream end face of said insert, and in a similar cavity in a counter-bearing. The counter-bearing comprises a central portion containing said cavity and is connected through radial sheet members to the wall of said passageway. A device is provided for sensing rotor revolutions and converting these into a signal representation of the fluid flow rate.
