ABSTRACT:
A water meter has a measurement insert disposed in a meter housing, a measurement display, an intake connection and a discharge connection. An impeller is disposed on a shaft in a measurement insert housing, and a first shaft end of the shaft interacts with the measurement display. A supporting part is disposed between the meter housing and the measurement insert housing. Because of the supporting part, forces, acting in the axial direction of a second shaft end of the shaft through the measurement insert housing, can be absorbed and the forces can be conducted into the meter housing.
