the center gear is equipped with four samarium cobalt magnets,which are not easy to weathering、degaussing and losing data.this ensures the life of the central transmission part of the water meter and the accuracy of measurement.
the counter disc is made of POM,with porcelain,clear reading and durable sercvice life.Fixed with screws,easy to replace.With double reed switch design,if one of them is damaged,it can still work normally.
3.Anti Magnetic Ring
When the reed switch is installed,the anti-magnetic ring is added,the pig iron material is required,and the signal strength of the magnet steel is required to be 3000-4000 gauss,which ensures the stable output of the pulse signal.
the impeller shaft is made of stainless steel、agate、bushing and corundum.The service life and accuracy are guaranteed.
high precision die,1 million sets will be replaced to ensure small error,high throughput,and ensure the accuracy of water meters and delivery time.
