A liquid meter with a single jet of the type including a motor member transmitting its movement to a totalizer via a transmission mechanism constituted by an axle whose one end is secured in rotation to the motor member (1) and whose other end is engaged in a chamber, provided in a housing (2) enclosing a gear train and a drive axle of the totalizer, through an opening provided in the partition (6) of the housing (2), the end including a pinion coacting with a pinion mounted on the drive axle of the totalizer, and protective elements (10) for the axle (4). The protective elements are arranged to prevent the passage of solid particles contained in the liquid through the opening (5) toward the chamber (3) by defining a protected zone of least turbulence surrounding the axle (4) adjacent the opening (5) and promoting the fall by gravity of the particles which lose their initial kinetic energy during their movement toward the opening (5).
