Yiziphi izinhlobo ezimbili ze-ultrasound flow meter?

Amamitha okugeleza e-Ultrasonic ahlukaniswe ngokuyinhloko ngezinhlobo ezimbili eziyinhloko ngokusekelwe ezimisweni zawo zokusebenza:

1. Amamitha Okugeleza E-Ultrasonic Esikhathi Sokuhamba
• Indlela Ezisebenza Ngayo:
• Linganisa umehluko esikhathini sokuhamba kwezibonakaliso ze-ultrasound phakathi kwama-transducer amabili:
• Ezansi (ngokugeleza): Isignali ihamba ngokushesha.
• Phezulu (ngokumelene nokugeleza): Isignali ithatha isikhathi eside.
• Umehluko wezikhathi zokuhamba (\Delta t) ulingana nesivinini sokugeleza koketshezi.
• Izici Eziyinhloko:
• Kungcono kakhulu koketshezi oluhlanzekile noma olucishe luhlanzeke (isib. amanzi, uwoyela, noma uketshezi olune-viscosity encane).
• Kunembile kakhulu (±0.5% kuya ku-±2.0% ngaphansi kwezimo ezifanele).
• Ayihlaseli futhi isetshenziswa kabanzi ezimbonini ezahlukene.
• Izinzuzo:
• Isebenza kahle ngoketshezi olufana nolwenziwe ngoketshezi.
• Ifanelekela ububanzi obukhulu bosayizi wepayipi nezinto zokwakha.
• Kutholakala ukufakwa okuphathekayo noma okuhlala njalo.
• Imikhawulo:
• Ukunemba kuncipha uma uketshezi luqukethe amazinga aphezulu ezinhlayiya, amabhamuza, noma ukungcola.

2. Amamitha Okugeleza Kwe-Doppler Ultrasonic
• Indlela Ezisebenza Ngayo:
• Linganisa ukushintsha kwemvamisa (umphumela we-Doppler) kwezimpawu ze-ultrasonic ezibonisa izinhlayiya noma amabhamuza ngaphakathi koketshezi.
• Umehluko phakathi kwezibonakaliso ezidlulisiwe nezibonisiwe usetshenziselwa ukubala ijubane lokugeleza.
• Izici Eziyinhloko:
• Yenzelwe uketshezi olunezinhlayiya noma amabhamuza alengayo (isb., amanzi angcolile, ama-slurry, noma uketshezi olungcolile).
• Ukunemba ngokuvamile kuphansi kunamamitha esikhathi sokuhamba (±1.0% kuya ku-±5.0%).
• Izinzuzo:
• Ingalinganisa ukugeleza koketshezi olungabonakali noma olunezigaba eziningi.
• Kufanelekela ukusetshenziswa kwezimboni kanye namanzi angcolile.
• Imikhawulo:
• Kudinga ukuhlushwa okuncane kwezinhlayiya noma amabhamuza (ngokuvamile >100 ppm).
• Akufanele uketshezi oluhlanzekile.

Lezi zinhlobo ezimbili zinakekela izinhlelo zokusebenza ezahlukene, amamitha esikhathi sokuthutha ahamba phambili ngokunemba koketshezi oluhlanzekile kanti amamitha e-Doppler afanelekela ukugeleza okunzima noma kwesigaba esixubile.
