The internal structure of the traditional water meter can be divided into three parts, namely a shell, a sleeve and an inner core from outside to inside. The housing is pig iron cast and water passes through the lower annular space of the housing after exiting the water inlet, referred to herein as the "lower annular chamber". An upper annular chamber is arranged above the annular space and communicated with the water outlet. The bottom of the sleeve is provided with a filter screen with small holes for filtering impurities in water. The side of the sleeve is provided with an upper row of round holes and a lower row of round holes, the positions of the holes are just opposite to the upper ring chamber and the lower ring chamber of the shell, and obviously, the lower row is a water inlet hole, and the upper row is a water outlet hole. It is particularly notable that both rows of holes are drilled diagonally along the tangent of the circle. Note that the upper and lower rows of holes are in opposite directions. The water flows in from the lower discharge hole along the tangential direction, so that a rotating water flow is formed, which is important for the operation of the water meter. The inner core is divided into an upper layer, a middle layer and a lower layer, and the upper layer is seen from the glass window, and only the pointer and the dial are arranged. The most critical is the lower layer, inside which there is a plastic wheel with a number of plastic blades, called "impellers".
However, in view of the poor installation environment of some water meters, the impurities in the water cause damage to the internal structure of the water meter during long-term use, so that a pre-filter installed in front of the water meter for filtering the water quality needs to be designed.
