Isikhokelo soFakelo lwe-UOC Series Open Channel Flowmeter

Esi sikhokelo sichaza iinkqubo eziphambili zokufaka zombini iyunithi yokusingatha kunye neprobe, sigubungela izinto eziqwalaselwayo kwindalo, ukufakwa koomatshini, kunye nokuseta okucwangcisiweyo kwesicelo. La macandelo alandelayo abonelela ngemiyalelo eneenkcukacha ukuqinisekisa ukuchaneka kokulinganisa kunye nozinzo lwenkqubo lwexesha elide.

I. Iingcebiso zokufakelwa kwehostele l

•Ihostele akufuneki ifakwe kwindawo exineneyo apho amaqondo obushushu anokudlula ubushushu obuqhelekileyo bokusebenza (-40~+75), ukuba ihostele ifakwe ngaphandle, kufuneka ikhuselwe elangeni elithe ngqo okanye kwiimeko zemozulu ezimbi.

•Qinisekisa ukuba umphezulu wokufakelwa awuchaphazeleki kukungcangcazela kwaye awukho kufutshane

kwiintambo zevolthi ephezulu, iicontactors okanye ii-drive controls.

•Khetha ii-knockouts ezifanelekileyo kwisiseko sendawo ebiyelweyo kwaye ufake ii-cable glands ezifanelekileyo ukugcina umlinganiselo we-IP67.

•Musa ukusebenzisa amandla agqithisileyo xa uqinisa ukubopha kwaye uphephe naluphi na uphazamiseko lwendawo ebiyelweyo. •Nika ingqalelo kubukhulu bombungazi kunye nendawo ebiyelweyo.

II.Iingcebiso zokufakela iprobel

•Iprobe inganikezelwa njengesiqhelo okanye nge-screw nut okanye nge-flange e-odolweyo.

•Qinisekisa ukuba iprobe ifakelwe ngokuthe nkqo kumphezulu ojongiweyo kwaye kungcono, ubuncinane i-0.25 yeemitha ngaphezulu kwayo, kuba iprobe ayinakufumana mpendulo kwindawo engabonakaliyo.

•Iprobe ine-10 inclusive conical beam angel kwi-3 dB kwaye kufuneka ifakwe ngombono ocacileyo welwelo oluza kulinganiswa. Kodwa itanki ye-weir esecaleni ethe nkqo egudileyo ayizukubangela imiqondiso yobuxoki.

•Ngokubaimitha yokuhamba komjelo ovulekileyo wohlobo lweflumeufakelo, beka iprobe phezulu kwesakhiwo sokulinganisa.

•Musa ukuqinisa kakhulu iibholithi kwiflange.

•Xa uyifaka kwindawo ebandayo, khetha i-sensor ende kwaye wenze i-sensor inwebe kwisitya, uphephe i-frost kunye ne-icing.

•Kwi-Parshall flume, i-probe kufuneka ifakwe kwindawo eyi-2/3 yokufinyela kude nomphimbo.

•Ngokubai-flowmeter evulekileyo yetshaneli yohlobo lwe-weirizicelo (ii-V-Notch kunye nee-rectangular weirs), faka i-probe kwicala elingasentla kumgama ophindwe ka-3-4 ubunzulu bamanzi obuphezulu ngaphezu kwe-weir crest.
