Abstract
The invention provides a liquid meter comprising a measurement chamber in which a spinner is caused to rotate about an axis and pivots, at least at low liquid flow rates, on a support in alignment with the axis. The pivoting motion takes place via a ball that is free to rotate between two concave surfaces each having a radius of curvature that is greater than the radius of curvature of the ball. One of the concave surfaces is tied to the spinner, whereas the other surface is secured to the support.
