1. Xa ulinganisa ulwelo, i-vortex flowmeter kufuneka ifakwe kwipayipi ezaliswe ngokupheleleyo ngomgangatho olinganisiweyo.
2. Xa i-vortex flowmeter ifakiwe kumbhobho othe tyaba, ifuthe lobushushu beliphakathi kumthumeli kufuneka liqwalaselwe ngokupheleleyo.
3. Xa i-vortex flowmeter ifakiwe kumbhobho othe nkqo, ezi mfuno zilandelayo kufuneka zifezekiswe:
a) Xa kulinganiswa irhasi. Amanzi anokuhamba nakweyiphi na indlela;
b) Xa kulinganiswa ulwelo, ulwelo kufuneka luhambe ukusuka ezantsi ukuya phezulu.
4. Umjelo osemazantsi we-vortex flowmeter kufuneka ubenobude obuthe ngqo obungekho ngaphantsi kwe-5D (ubukhulu bemitha), kwaye ubude bombhobho onyukayo othe ngqo we-vortex flowmeter kufuneka uhlangabeze ezi mfuno zilandelayo:
a) Xa ububanzi bombhobho wenkqubo bukhulu kunobubanzi besixhobo (D) kwaye idayimitha ifuna ukunciphisa, ayiyi kuba ngaphantsi kwe-15D;
b) Xa ububanzi bombhobho wenkqubo buncinci kunobubanzi besixhobo (D) kwaye ububanzi kufuneka bandiswa, awuyi kuba ngaphantsi kwe-18D;
c) Xa kukho ingqiniba okanye iteyiphu engama-900 phambi kwesixhobo sokuhamba, hayi ngaphantsi kwe-20D;
d) Xa kukho iingqiniba ezimbini ezilandelelanayo ezingama-900 kwindiza enye phambi kwe-flowmeter, engekho ngaphantsi kwe-40D;
e) Xa uqhagamshela iingqiniba ezingama-900 kwiiplanethi ezahlukeneyo phambi kwe-flowmeter, hayi ngaphantsi kwe-40D;
f) Xa isilinganisi-manzi sifakelwe emazantsi evalve elawulayo, hayi ngaphantsi kwe-50D;
g) Isilungisi esinobude obungekho ngaphantsi kwe-2D sifakwe phambi kwesixhobo sokuhamba, 2D phambi kwesilungisi, kunye nobude bombhobho othe tye ongekho ngaphantsi kwe-8D emva komlungisi.
5. Xa igesi inokuvela kulwelo oluvavanyiweyo, kufuneka kufakelwe isixhobo sentsimbi.
6. I-vortex flowmeter kufuneka ifakwe kwindawo apho ingayi kubangela ukuba umbane uphefumle.
7. Ukuphambuka phakathi kwedayamitha yangaphakathi yecandelo elingaphambili nelingasemva leepayipi ze-vortex flowmeter kunye nobubanzi bangaphakathi be-flowmeter akufuneki bube ngaphezulu kwe-3%.
8. Kwiindawo apho inqaku lokuchonga (i-vortex generator) linokonakala, ngaphambili kunye nangemva kwezivalo zokumisa kunye neepasile zokudlula kufuneka zongezwe kufakelo lombhobho we-vortex flowmeter, kunye ne-plug-in vortex flowmeter kufuneka ixhotyiswe nge-shut- ngaphandle kwebhola.
9. Iiflowmeters zeVortex akufuneki zifakelwe kwiindawo eziphantsi kwentshukumo.
