Uma ulinganisa imidiya ekhethekile yamakhemikhali, njengoba kungekho nketho yezinhlobo ezikhethekile zamakhemikhali kumuntu ophethe, kuyadingeka ukufaka ngesandla ijubane lomsindo le-medium ekhethekile yamakhemikhali. Kodwa-ke, ngokuvamile kunzima ukuthola ijubane lomsindo le-medium ekhethekile yamakhemikhali. Kulesi simo, kuyadingeka ukusebenzisa i-flowmeter ye-ultrasonic yomehluko wesikhathi ukulinganisa ijubane lomsindo.
1) Imenyu ye-M11-M16 isetha amapharamitha afanele omzila;
2) I-M23 ikhetha uhlobo lwenzwa, i-M24 ikhetha indlela yokufaka inzwa;
3) Kumenyu yohlobo loketshezi lwemenyu ye-M20, khetha okuthi “okunye”, faka u-1482 kusivinini somsindo woketshezi lwe-M21, bese ugcina inani elizenzakalelayo elingu-1.0038 kumenyu ye-M22;
4) Faka inzwa ngokwebanga lokufakwa elibangelwa yi-M25, bese ufaka imenyu ye-M90, lungisa isikhala senzwa ukuze wandise inani le-S kanye nenani le-Q, bese uzinzisa.
5) Faka imenyu ye-M92 ukuze urekhode imitha ukuze ulinganisele ijubane lomsindo, bese ufaka leli nani kumenyu ye-M21.
6) Phinda izinyathelo 4-5 kuze kube yilapho ijubane lomsindo elilinganisiwe eliboniswe kumenyu ye-M92 lifana nokufakwa kwejubane lomsindo kumenyu ye-M21, bese kuqedwa ukuqagela ijubane lomsindo le-medium ekhethekile yamakhemikhali, bese kuqaliswa ukukalwa kokugeleza kwe-medium ekhethekile yamakhemikhali.
