A liquid meter includes a housing with two compartments with respectively a motor member disposed in the path of movement of a stream of the liquid to be measured and a counter, the transmission of the movement of the motor member to the counter being carried out through the separation wall of the compartments with the aid of a magnetic drive device having a pair of magnets, the first magnet associated with the motor member having a face with double polarity in magnetic equilibrium with a face of double polarity of the magnet associated with the counter, each magnet has at least one double polarity on each of its other faces.

A measuring device for a liquid meter with oscillating piston comprises a hollow chamber pierced with two apertures and limited by a cylindrical side wall, a bottom and a lid; a piston enclosed in said chamber and held movably, along a partition wall about a well. This device further comprises at least one groove, made in the corners formed between the bottom and the side wall of the chamber or the well or the piston, that opens into the hollow of the chamber, in a space formed between the well and the side walls, and is designed to receive deposits of particles introduced into said device by the liquid to be metered. The device can be applied in particular to water metering. FIG. 3
