1. The Counting Part
（1）Register: POM (polyformaldehyde) material, porcelain white color，which ensures the pure material production, without adding any waste, and with strong wear resistance.
（2）Central Gear: Vertical design to ensure its coaxality.
2、The Measuring Part
（1）Turbine Component: It is made of stainless steel, inset bushings and corundum for improved wear resistance.
（2）Measuring Chamber: The mould is made of high quality material, which ensures small error and high pass rate.
In addition to accidents, every 1 million sets of molds produced will be replaced to ensure high precision.
（3）Bottom Strainer: The bottom filter is designed to minimize the impact of the filter on accuracy.
二、The bearer- Body part
1、Brass Tail piece: The copper content of raw materials is 59%, the lowest value is 57%, and the copper content is 55%-56%, which is prone to fracture.
2、Body:The average wall thickness is 2.5-2.7mm
3、Coupling Nut: Guarantee its length and weight, the weight will not be lower than 140g, otherwise it will be easy to break.
