Description: The internal structure of the traditional water meter can be divided into shell, sleeve, core three pieces from the outside to inside. The shell of water meter is casting of cast iron, and the water passes through the lower annular space of the shell after it comes out of the water inlet, which is called the "lower chamber". there are the "upper ring room" and the outlet connected on the circular space of water meter. At the bottom of the sleeve, there is a filter with a small hole in the water meters, filtering out the debris in the water. there are two rows of circular holes in the upper and lower rows inside of the sleeve. The position of the hole is exactly opposite to the upper and lower ring chambers of the casing. Obviously, the lower row is the water inlet and the upper row is the water outlet. particularly noteworthy, these two rows of holes are diagonal along the tangential direction of the circle. Note that the upper and lower rows of holes are in the opposite direction. Water flows from the lower row of holes along the tangential direction, which is bound to form a rotating water flow in the water meters, which is very important for the work of the water meter. Inner core is divided into upper, middle and lower, see the upper from the glass window, only the pointer and dial. In fact, the most critical is the lower, there is a plastic round, there are many plastic leaves on the round, called "impeller".
