Izidingo zokukhetha zamamitha okugeleza kagesi

Izidingo zokukhetha zeama-electromagnetic flow metresfaka amaphuzu alandelayo:

Linganisa i-medium. Cabangela conductivity, corrosiveness, viscosity, izinga lokushisa, kanye nokucindezela medium. Isibonelo, imidiya ye-conductivity ephezulu ifanele izinsimbi ezincane zekhoyili yokungeniswa, imidiya ebolayo idinga izinto ezimelana nokugqwala, futhi imidiya ye-viscosity ephezulu idinga izinzwa ezinobubanzi obukhulu.
Ukunemba kokulinganisa. Khetha ileveli yokunemba efanele ngokusekelwe ezidingweni zokulinganisa, ngokunemba okuphansi okufanele amazinga okugeleza okuphezulu nokunemba okuphezulu okulungele ukugeleza okuphansi.

I-Caliber kanye nezinga lokugeleza. Khetha ububanzi obufanele kanye nobubanzi bokugeleza ngokusekelwe esilinganisweni sokugeleza nosayizi wamapayipi, futhi unake ukufanisa ububanzi bokugeleza nezinga lokugeleza langempela.
Ingcindezi yomsebenzi kanye nezinga lokushisa. Khetha ingcindezi yokusebenza efanele kanye nebanga lokushisa ukuze uqinisekise ukusebenza kwethuluzi.

Izinto ze-Electrode nokumelana nokugqoka. Khetha izinto ezifanele zama-electrode kanye nokumelana nokugqoka okusekelwe kuzimo zangempela zohlelo lokusebenza.

Izimo zokufakwa kanye nezici zemvelo. Khetha uhlobo lwensimbi olufanele nendlela yokufaka ngokusekelwe endaweni yangempela yokufaka kanye nezimo.
Izici zoketshezi oluhlolwayo. Amamitha okugeleza kwe-electromagnetic alungele uketshezi olusebenzayo futhi awafanele amagesi, uwoyela, namakhemikhali emvelo.

Ibanga lokulinganisa nezinga lokugeleza. Isivinini sokugeleza ngokuvamile sinconywa ukuthi sibe phakathi kuka-2 no-4m/s. Ezimweni ezikhethekile, njengoketshezi oluqukethe izinhlayiya eziqinile, isivinini sokugeleza kufanele sibe ngaphansi kuka-3m/s.

Izinto ze-lining. Khetha izinto ezifanele zamalayini ezisuselwe kuzinto ezibonakalayo namakhemikhali emaphakathi, njengezinto ezimelana nokugqwala nezingagugi.
Isignali yokuphuma kanye nendlela yokuxhuma. Khetha uhlobo olufanele lwesignali yokuphumayo (efana no-4 kuya ku-20mA, okukhipha imvamisa) kanye nendlela yokuxhuma (njengokuxhumeka kwe-flange, uhlobo lwe-clamp, njll.).

Izinga lokuvikela kanye nohlobo olukhethekile lwezemvelo. Khetha izinga elifanele lokuvikela (elifana ne-IP68) kanye nohlobo olukhethekile lwezemvelo (njengokungena emanzini, okungaqhumi, njll.) ngokuya ngendawo yokufaka.
