1. Lapho ukala uketshezi, i-vortex flowmeter kufanele ifakwe epayipini eligcwele ngokuphelele into elinganisiwe.
2. Uma i-vortex flowmeter ifakwe epayipini elibekwe ngokuvundlile, ithonya lokushisa kwe-medium kumthumeli kufanele licatshangelwe ngokugcwele.
3. Uma i-vortex flowmeter ifakwe epayipini eliqondile, lezi zidingo ezilandelayo kufanele zihlangatshezwe:
a) Uma ukala igesi.Uketshezi lungageleza kunoma iyiphi indlela;
b) Lapho ukala uketshezi, uketshezi kufanele lugeleze lusuka phansi luye phezulu.
4. Umfula ongezansi we-flowmeter ye-vortex kufanele ube nobude bepayipi obuqondile obungekho ngaphansi kuka-5D (ububanzi bemitha), futhi ubude bepayipi eliqondile elikhuphuka nomfula le-flowmeter ye-vortex kufanele buhlangabezane nezimfuneko ezilandelayo:
a) Uma ububanzi bepayipi lenqubo bukhulu kunobubanzi bensimbi (D) futhi ububanzi budinga ukuncishiswa, akumele bube ngaphansi kuka-15D;
b) Uma ububanzi bepayipi lenqubo buncane kunobubanzi bensimbi (D) futhi ububanzi budinga ukunwetshwa, akumele bube ngaphansi kuka-18D;
c) Uma kukhona indololwane noma i-tee engama-900 phambi kwe-flowmeter, hhayi ngaphansi kuka-20D;
d) Uma kunezindololwane ezimbili ezilandelanayo ezingama-900 endizeni eyodwa phambi kwe-flowmeter, hhayi ngaphansi kuka-40D;
e) Lapho uxhuma izindololwane ezimbili ezingama-900 ezindizeni ezahlukene phambi kwe-flowmeter, hhayi ngaphansi kuka-40D;
f) Uma i-flow meter ifakwe ezansi nomfula wevalvu elawulayo, hhayi ngaphansi kuka-50D;
g) Isilungisisi esinobude obungekho ngaphansi kuka-2D sifakwa ngaphambi kwe-flowmeter, i-2D phambi kwesilungisi, kanye nobude bepayipi obuqondile obungekho ngaphansi kuka-8D ngemva kwesilungisi.
5. Uma igesi ingase ivele oketshezini oluhloliwe, kufanele kufakwe i-degasser.
6. I-vortex flowmeter kufanele ifakwe endaweni lapho ingeke ibangele ukuthi uketshezi luhwamuke.
7. Ukuchezuka phakathi kobubanzi bangaphakathi bezingxenye zepayipi eziqondile zangaphambili nangemuva ze-vortex flowmeter kanye nobubanzi bangaphakathi be-flowmeter akufanele kube ngaphezu kuka-3%.
8. Ezindaweni lapho i-elementi yokubona (ijeneretha ye-vortex) ingase ilimale, amavalvu okumisa angaphambili nangemuva kanye nama-bypass valve kufanele kwengezwe ekufakweni kwepayipi le-vortex flowmeter, futhi i-plug-in vortex flowmeter kufanele ifakwe into yokuvala- i-valve yebhola.
9. Ama-flowmeters e-Vortex akufanele afakwe ezindaweni ezingaphansi kokudlidliza.
