In meter, there are three plungers assembled to the measuring chambers (cylinders). The plungers are connected to the wobble plate from the upsides. The wobble plate also has the wobble plate shaft assembled under itself. The wobble plate shaft moves the slider which slides between the plungers by controlling the sequence when the liquid enters the meter.
When the liquid enters the meter, first it flows from the upper cover into the casing. The slider is ready to open the measurement chambers. As soon as the pressure under it releases and the upper cover full of liquid, the plunger is forced to move to the bottom and by this, it pushes the liquid to the outlet. At that moment, another plunger moves from bottom to top. The slider is moved by the wobble plate to open an another measuring room entrance. While the plungers are moving to the top, the liquid flows from bottom to inside of the measuring rooms. This cycle continues with the incoming of the liquid. When the liquid flow stops, the pressure in the inlet and outlet becomes equal and the cycle stops.
