HNF40-A Vortex Flowmeter Parameters
Tshwj xeeb Parameters	Tus nqi / Nqe lus piav qhia
Kev Ntsuas Txoj Cai	Cov ntse muaj vortex flowmeter ua haujlwm raws li txoj cai ntawm Karman vortex txoj kev. Thaum cov kua dej ntws los ntawm lub vortex- tsim lub cev nrog tus ncej peb sab hauv cov raj xa dej, kab vortex tsis tu ncua (piv txwv li, Karman vortex txoj kev) yog hloov pauv ntawm ob sab hauv qab. Qhov zaus ntawm vortex sib cais yog ncaj qha proportional rau tus nqi ntws ntawm cov kua. Lub sensor kuaj pom cov teeb liab zaus no los ntawm kev tsim- hauv piezoelectric cov ntsiab lus, thiab tom qab ua tiav los ntawm lub microprocessor thiab cov khoom siv ntse ntse, nws tuaj yeem suav qhov tseeb ntawm cov kua dej tam sim no thiab sib sau ua ke, thiab tso tawm cov teeb liab txheem.
