Nyob rau hauv lub tshav pob ntawm niaj hnub automation, lub flow meter plays lub luag hauj lwm tseem ceeb heev. Tsis tsuas yog nws tuaj yeem saib xyuas qhov nruab nrab ntws hauv lub sijhawm tiag tiag, tab sis kuj tseem nyob hauv qhov no ntawm automation, ntau lub tuam txhab kev lag luam tau txo qis ntau ntawm cov neeg ua haujlwm thiab cov khoom siv. Qee hom flowmeters feem ntau ntsuas roj thiab kua: electromagnetic flowmeter, vortex flowmeter, thermal mass flowmeter, orifice flowmeter, turbine flowmeter, V-cone flowmeter, orifice flowmeter, ntxeem tau qhov dej ntws ntsuas, hlau rotor flowmeter, thiab lwm yam.
Qhov tseeb, thaum xaiv cov qauv, cov neeg siv tuaj yeem xaiv qhov tsim nyog flowmeter raws li ib puag ncig thiab kev ua haujlwm ntawm daim ntawv thov daim teb thiab peb yam ntawm qhov nruab nrab kub thiab siab. Yog tias qhov kev xaiv tsis raug raws li tus nqi, nws yuav tsis tsuas cuam tshuam cov flowmeter ntsuas thiab tswj qhov system, thiab kuj tseem txo qis kev pab cuam lub neej ntawm flow meter.
