1. Xa ulinganisa ulwelo, i-vortex flowmeter kufuneka ifakwe kumbhobho ozaliswe ngokupheleleyo ngomlinganiselo ophakathi.
2. Xa i-vortex flowmeter ifakwe kwipayipi ebekwe ngokuthe tye, impembelelo yeqondo lokushisa eliphakathi kwi-transmitter kufuneka ithathelwe ingqalelo ngokupheleleyo.
3. Xa i-vortex flowmeter ifakwe kumbhobho othe nkqo, ezi mfuno zilandelayo kufuneka zifezekiswe:
a) Xa kulinganiswa irhasi.Ulwelo lunokuqukuqela nakweliphi na icala;
b) Xa ulinganisa ulwelo, ulwelo kufuneka luhambe ukusuka ezantsi ukuya phezulu.
4. Umlambo osezantsi we-vortex flowmeter kufuneka ube nobude bombhobho othe tye ongekho ngaphantsi kwe-5D (ububanzi beemitha), kunye nobude bombhobho othe ngqo onyukayo we-vortex flowmeter kufuneka buhlangabezane nezi mfuno zilandelayo:
a) Xa ububanzi bombhobho wenkqubo bukhulu kunobubanzi besixhobo (D) kwaye ububanzi kufuneka buncitshiswe, abuyi kuba ngaphantsi kwe-15D;
b) Xa ububanzi bombhobho wenkqubo buncinci kunobubanzi besixhobo (D) kwaye ububanzi bufuna ukwandiswa, akuyi kuba ngaphantsi kwe-18D;
c) Xa kukho ingqiniba ye-900 okanye i-tee phambi kwe-flowmeter, ingekho ngaphantsi kwe-20D;
d) Xa kukho iingqiniba ezimbini ezilandelelanayo ezingama-900 kwinqwelo-moya enye phambi kwe-flowmeter, kungabi ngaphantsi kwe-40D;
e) Xa udibanisa ii-elbows ezimbini ze-900 kwiindiza ezahlukeneyo phambi kwe-flowmeter, kungekhona ngaphantsi kwe-40D;
f) Xa isilinganisi-manzi sifakwe ezantsi kwevalve elawulayo, ingabi ngaphantsi kwe-50D;
g) Isilungisi esinobude obungekho ngaphantsi kwe-2D sifakwe phambi kwe-flowmeter, i-2D phambi kwesilungisi, kunye nobude bombhobho othe ngqo ongekho ngaphantsi kwe-8D emva kokulungiswa.
5. Xa igesi inokuvela kulwelo oluvavanyiweyo, i-degasser kufuneka ifakwe.
6. I-vortex flowmeter kufuneka ifakwe kwindawo apho ingayi kubangela ukuba ulwelo lube ngumphunga.
7. Ukutenxa phakathi kobubanzi bangaphakathi bombhobho othe ngqo wangaphambili nangasemva we-flowmeter ye-vortex kunye nobubanzi bangaphakathi be-flowmeter akufanele kube ngaphezu kwe-3%.
8. Kwiindawo apho into yokubona (ijenereyitha ye-vortex) inokonakala, iivalvu zangaphambili nasemva zokumisa kunye neevalvu zokudlula kufuneka zongezwe kufakelo lombhobho we-flowmeter ye-vortex, kunye ne-plug-in vortex flowmeter kufuneka ixhotyiswe ngokuvalwa- vala ivalve yebhola.
9. Ii-flowmeters zeVortex akufuneki zifakwe kwiindawo eziphantsi kwe-vibration.
