1, by magnet set come phase magnet, surrounding is positioned when being put into impeller mold, magnet when high temperature and pressure forms
It will not be crooked, it is ensured that magnet positions are consistent, and product stability is good, while impeller quadrangle balanced weight, and deviation is small, rotational frequency temperature
It is fixed, test error is reduced, impeller is molded processing, and structure is sound and reliable, can bear hyperbaric environment impact；
2, magnet set is formed using environment friendly plastic rubber material, and group of magnets puts on mounted in magnet, and when magnet and magnet sleeve forming wraps
It is wrapped in impeller, magnet does not have exposed, avoids directly contacting with water, and solving magnet influences quality problem, and product can be safe to use；
3, impeller body inner magnet polarity is opposite two-by-two, and magnet quantity can be changed according to impeller shape demand, can
Selection 2 magnet of installation or 4 magnet, so that the variation of flowmeter output frequency, meets the needs of client and market are to product；
4, impeller body and shell are assembled, and because magnet positions are unified, incuded with external Hall IC and are stablized, water flows through
Out-of-date, flowmeter output data is accurate, improves Product Precision requirement.
