Meizhi ndi kampani yayikulu kwambiri padziko lonse lapansi yopanga ma compressor oziziritsa mpweya komanso kompresa yamafiriji yomwe ikukula kwambiri. Kuyambira 2006, ma compressor a firiji a Meizhi adakhala pamalo oyamba padziko lonse lapansi potengera kupanga ndi kuchuluka kwa malonda, ndikukhala omwe akukula kwambiri padziko lonse lapansi kupanga ndi kugulitsa. Imodzi mwamakampani opanga firiji kompresa.
The zitsulo chubu zoyandama flowmeter, electromagnetic flowmeter, kuthamanga transmitter, ndi vortex flowmeter ya Sinomeasure mtundu zagwiritsidwa ntchito bwino kulamulira wanzeru mpweya unsembe unsembe benchi mayeso. Kuyeza ndi kuwongolera koyenera kwa magawo ofunikira popanga zinthu monga kuyenda kwa mpweya, pakali pano, ndi nthunzi zakhala gawo lofunikira pakuwongolera kwa Meizhi pamlingo wamagetsi mufakitole.
