Ungabhekana kanjani nomehluko phakathi kokufakwa kanye ne-flowmeter ye-clamp-on ngaphandle kwenani lika-S, Q noma inani layo lika-S, Q liphansi, ungahlola kanjani ukuthi yiziphi izimbangela?

1) Qinisekisa ukuthi indawo ezungezile iyahlangabezana nezidingo: ubude obanele besigaba sepayipi eliqondile, indawo yokulinganisa egcwele nelinganiswayo, akukho nqwaba yamabhamuza noma izinhlayiya zokungcola epayipini.

2) Buza ikhasimende ukuthi amapharamitha ephayiphi alungile yini, ukuthi kukhona yini ungqimba kanye nobubanzi ephayiphini, ukuthi ngabe indawo yokulinganisa ikhethwe kahle yini, hlola ukuthi amapharamitha okusingatha asethwe kahle yini, uma kukhona ungqimba, izinto zongqimba zingalinganiswa. Ngenzwa yangaphandle eboshwe, qiniseka ukuthi udonga lwangaphandle lwephayiphi lucwebezelisiwe futhi i-coupling agent isetshenziswa ngokulinganayo nangokufanele;

3) Hlola ukuthi inzwa ifakwe kahle yini (Faka inzwa ngokuya ngesikhala senzwa esiboniswe kumenyu ye-M25) yenzwa ye-plug-in, hlola ukuthi inzwa iqondile yini;

4) Hlola ukuthi izintambo zenzwa zilungile yini, hlola imenyu ye-M91, qaphela isilinganiso sokudlulisa isikhathi, bese ulungisa ukufakwa kwenzwa ukuze kube ngaphakathi kobubanzi obungu-97%-103%;

5) Uma isilinganiso sokudlulisa isikhathi siphakathi kuka-97%-103%, kodwa inani le-S kanye nenani le-Q lisaphansi, okubonisa ukuthi ububanzi bepayipi bukhulu noma ubukhulu bodonga bukhulu, sicela ufake esikhundleni sendlela yokufaka inzwa engu-Z;

6) Uma isilinganiso sokudlulisa isikhathi singenakushintshwa sibe ngu-97%-103%, noma inani le-S kanye nenani le-Q lihlala lingu-0, futhi izinyathelo ezingenhla zilungile, kungase kube nenkinga ngenzwa noma i-host, susa inzwa bese usebenzisa indlela yemibuzo emibili engenhla ukuze unqume.
