Isipiliyoni Sokukhiqiza Seminyaka engu-20+

Amacebo okufakwa kwe-probe ( imitha yokugeleza yesiteshi evulekile ye-UOL )

1. I-probe ingahlinzekwa njengokujwayelekile noma nge-screw nut noma nge-flange e-odiwe.
2. Ngezinhlelo zokusebenza ezidinga ukuhambisana kwamakhemikhali uphenyo luyatholakala luvalelwe ngokugcwele ku-PTFE.
3. Ukusetshenziswa kokufakwa kwensimbi noma ama-flange akunconywa.
4. Ezindaweni ezisobala noma ezinelanga kunconywa isivikelo.
5. Qinisekisa ukuthi i-probe ifakwe i-perpendicular endaweni egadiwe futhi ngokufanelekile, okungenani amamitha angu-0.25 ngaphezu kwayo, ngoba i-probe ayikwazi ukuthola impendulo endaweni eyimpumputhe.
6. I-probe inengelosi eyi-conical beam eyi-10 ehlanganisiwe ku-3 db futhi kufanele ifakwe ngokubona okucacile okungavinjelwe koketshezi okumele lukalwe.Kodwa ama-sidewalls amile abushelelezi ethangi le-weir ngeke abangele amasignali angamanga.
7. I-probe kumele ibekwe phezulu kombhobho noma i-weir.
8. Ungawaqinisi kakhulu amabhawodi ku-flange.
9. Umthombo othulisa ungasetshenziswa lapho kunokuguquguquka kwamanzi noma udinga ukuthuthukisa ukunemba kokulinganisa izinga.Umthombo osekhona uxhuma phansi kwe-weir noma i-flume, futhi i-probe ikala izinga emthonjeni.
10. Uma ufaka endaweni ebandayo, kufanele ukhethe inzwa yokwelula futhi wenze inzwa inwebe esitsheni, igweme isithwathwa kanye noqweqwe.
11. Nge-Parshall flume, i-probe kufanele ifakwe endaweni yokufinyela okungu-2/3 kude nomphimbo.
12. Ku-V-Notch weir kanye ne-rectangular weir, i-probe kufanele ifakwe ohlangothini olungenhla nomfula, ukujula okukhulu kwamanzi phezu kwe-weir kanye nezikhathi ezi-3~4 kude ne-weir plate.
