Abstract

An improved arrangement in a liquid flow meter which contains at least one cylindrical measuring means rotating in a measuring chamber with the measuring means sliding with its one end face against a bottom part of the measuring chamber in which a stable, bell-shaped stiffening element rests against the edge of the bottom part and is arched thereover on the side facing away from the measuring chamber with a rigid connecting member attached to the bottom part and the stiffening element at least in the central region of the bottom part. Preferably support ribs with an external shape corresponding to the inner contours of the bell-shaped stiffening element are connected firmly with the bell-shaped stiffening element.

In a liquid flow meter through which can be passed both warm and cool liquids, the meter including a measuring chamber having base members between which at least one rotatable measuring member having end-faces is mounted so that the end-faces glide along the base members when the measuring member is rotated, the improvement comprising:

a support structure for at least one of the base members to prevent the same from deflecting inwardly in response to the warm liquid whereby jamming of the rotatable member is precluded, said support structure including a bell-shaped stiffening member arranged at the side of the base member facing away from the measuring chamber, said stiffening member being joined to the base member about the periphery thereof;
and, a rigid connecting member joining the apex region of said bell-shaped member with the center region of the base member.
