Dab tsi yog Ultrasonic Flow Meter?
Ultrasonic flow meter ntsuas cov kua ntws tawm los ntawm kev xa cov cim ultrasonic los ntawm cov kua. Tus nqi ntws yog xam raws li qhov sib txawv ntawm qhov sib txawv los yog hloov zaus ntawm ultrasonic tsis.
Ultrasonic flow meter yog dav siv nyob rau hauv kev kho dej, HVAC systems, industrial pipelines, irrigation, roj av, tshuaj nroj tsuag, thiab municipal engineering vim hais tias lawv muaj:
- Tsis muaj kev poob siab
- Tsis muaj qhov txav
- Ib qho yooj yim installation
- Kev saib xyuas tsawg
- Kev ntseeg siab
- Haum rau cov yeeb nkab loj diameters
Txawm li cas los xij, cov kav dej sib txawv xav tau cov qauv sib txawv ultrasonic flow meter. Xaiv qhov tsis ncaj ncees lawm yuav ua rau cov teeb liab tsis ruaj khov, ntsuas tsis raug, lossis teeb meem nyuaj.
