1. Kwenzelwe i-Parshall Flume Hydraulics

• Ukusebenzisana nomklamo we-flume: Ama-flume e-Parshall aklanywe ukuguqula ijubane lokugeleza libe ukuphakama kwamanzi okulinganiselwe esigabeni esithile "somphimbo". Amamitha e-Ultrasonic alinganisa ngokunembile leli zinga elibucayi (ngokuvamile esigabeni esiphezulu somphimbo noma sokusondela kwe-flume) futhi asebenzise amafomula okukhipha i-flume e-Parshall ahlelwe kusengaphambili ukuze abale izinga lokugeleza.
• Amapharamitha e-flume alayishwe ngaphambilini: Amamodeli amaningi afaka izizindalwazi ezakhelwe ngaphakathi zobukhulu be-flume ye-Parshall ejwayelekile (isb., imiphimbo engu-1-intshi kuya ku-50-foot) kanye nama-coefficients azo okukhipha ahambisanayo, okususa ukufakwa kwefomula ngesandla nokuqinisekisa ukuhambisana nezindinganiso ze-hydraulic (isb., i-ASTM D1941).

2. Ukulinganisa Okungaphazamisi, Okunethonya Eliphansi

• Ukungathintani nokugeleza: Izinzwa ze-Ultrasonic zifakwe ngaphezu kwesigaba sokulinganisa i-Parshall flume (azikho izingxenye ezicwiliswe ngaphansi kwamanzi), zigwema ukuphazamiseka kwamaphethini okugeleza abalulekile e-flume. Lokhu kubalulekile ngoba ama-Parshall flume athembele ekugelezeni okungaphazamiseki ukuze alondoloze ukunemba.
• Akukho ingozi yokuvaleka: Ngokungafani nama-transducer okucindezela noma ama-weir plate, izinzwa ze-ultrasonic azithinteki yi-sediment, imfucumfucu, noma izinhlayiya ezintantayo ezivame emanzini angcolile, ekuniseleni, noma ekugelezeni kwezimboni—okuyisihluthulelo sama-flume asetshenziswa ekusetshenzisweni kwamanzi angcolile.

3. Ukunemba Okuphezulu Ezimweni Zokugeleza Okubalulekile

• Ukutholwa kwezinga okunembile: Ama-flume e-Parshall adinga ukulinganiswa kwezinga okunembile ezindaweni ezithile (isb., iphuzu lokulinganisa elingaphezulu) ukuze kubalwe ukugeleza. Izinzwa ze-Ultrasonic zinikeza ukunemba kwezinga okungu-±0.1% kuya ku-±0.5% wesilinganiso esigcwele, ngisho noma kukhona ukuxokozela okuncane noma isenzo samagagasi ku-flume.
• Ukuthembeka kokubala ukugeleza: Kusebenzisa i-Parshall flume's empirical discharge equation Q=C×Hn (lapho u-Q = izinga lokugeleza, u-H = ikhanda elilinganisiwe, u-C = i-coefficient, u-n = i-exponent), ehlanganiswe nedatha yezinga le-ultrasonic ukuqinisekisa imiphumela elandelelwa ezindinganisweni zomkhakha.

4. Ukuzivumelanisa nezimo nobukhulu be-Parshall Flume kanye nezicelo zayo

• Ihambisana nawo wonke amasayizi ajwayelekile: Isebenza ngama-flume amancane (elabhorethri) kuya kwamakhulu (ezimboni/ezolimo) e-Parshall, kusukela kuma-flume amancane (umphimbo ongu-1 intshi) kuya kuma-flume amakhulu emifuleni noma emiseleni (umphimbo ongamamitha angu-50).
• Iphatha ububanzi bokugeleza obuhlukahlukene: Ama-Parshall flume aklanyelwe ububanzi bokugeleza obuthile (isb., 0.01 kuya ku-300+ cfs), futhi amamitha e-ultrasonic avumelana nala mabanga ngokulinganisa izinguquko zamazinga ahambisanayo, ukuqinisekisa ukunemba kokubili ukugeleza okuphansi nokuphezulu.

5. Ukusebenza Okuqinile Ezindaweni Ezikhethekile Ze-Flume

• Ukumelana nokuphazamiseka okuhlobene ne-flume: Ukucubungula isignali okuthuthukisiwe kuhlunga umsindo ovela ekuchapheni, efomini, noma emabhamuzeni omoya—okuvamile kuma-flume e-Parshall ngenxa yokusheshisa kokugeleza emphinjeni.
• Isimo sezulu nokuqina kwemvelo: Izinzwa ezinezilinganiso ze-IP65/IP66/IP67 zimelana nemvula, umswakama, kanye nokushisa okuphezulu, okubaluleke kakhulu kuma-flume angaphandle ezindaweni zezolimo, zamanzi angcolile, noma zamanzi emvula.
• Umklamo ovimbela ukuphazamiseka: Unciphisa ukufundwa okungamanga okuvela elangeni, ukubonakaliswa kwezindonga ze-flume, noma imfucumfucu entanta phezu kwamanzi.

6. Ukufakwa okulula nokulinganiswa

• Ukufakwa okulula: Izinzwa zifakwa ngaphezu kwephuzu lokulinganisa le-flume (ngokuvamile ku-bracket noma ku-crossbar) ngaphandle komsebenzi wobuciko omncane, okugwema ukuguqulwa kwesakhiwo se-flume.
• Ukulinganisa okusheshayo: Kulungiselelwe kusengaphambili amajiyometri e-Parshall flume, kunciphisa isikhathi sokusetha. Abasebenzisi bangaqinisekisa ukunemba ngokuhlola amazinga okulula kumazinga okugeleza aziwayo.

7. Idatha Yesikhathi Sangempela Nokuhlanganiswa

• Ukuqapha okuqhubekayo: Kuhlinzeka ngesilinganiso sokugeleza kwesikhathi sangempela, izinga lamanzi, kanye nedatha yethrendi, eboniswa endaweni esikrinini noma edluliselwe ku-SCADA, PLCs, noma amapulatifomu amafu nge-Modbus, 4G/5G, Wi-Fi, noma i-LoRa.
• Ukugcinwa kwedatha: Kugcina idatha yokugeleza komlando (isb., isilinganiso sehora/sansuku zonke, ukugeleza okuphezulu) ukuze kubikwe ukuhambisana nomthetho, ukuhlela ukunisela, noma ukuthuthukisa ukwelashwa kwamanzi amdaka.
• Okuthusayo: Izexwayiso ezilungisekayo zamazinga aphezulu/aphansi (okubonisa ukuvinjelwa kwe-flume noma ukugcwala okukhulu) noma ukungasebenzi kahle kwenzwa, okuvumela ukulungiswa okusheshayo.

8. Ukugcinwa Okuphansi Nokuphila Isikhathi Eside

• Azikho izingxenye ezihambayo: Kuqeda ukuguguleka kwezingxenye zemishini, kunciphisa isikhathi sokungasebenzi. Ukugcinwa njalo kukhawulelwe ekuhlanzweni kwezinzwa njalo (ukususa uthuli noma ama-spider web) kanye nokuhlolwa kokulinganisa.
• Ukwakhiwa Okuhlala Isikhathi Eside: Izinzwa nama-transmitter akhiwe ukuze amelane nezimo ezinzima, okuqinisekisa impilo yesevisi ende ngisho nasezindaweni zangaphandle noma zezimboni.

9. Izindleko Ezingcono Zezinhlelo Ze-Flume

• Izindleko eziphelele zobunikazi ziphansi uma kuqhathaniswa namamitha aphazamisayo: Asikho isidingo sezinzwa ezicwiliswe emanzini (ezidinga ukushintshwa njalo ngenxa yokugqwala noma ukuvaleka) noma ukuguqulwa kwe-flume.
• Kunciphisa izindleko zabasebenzi: Ukufakwa okulula kanye nokugcinwa okuncane kunciphisa izindleko zokusebenza ngokuhamba kwesikhathi.

10. Ukuhambisana Nezindinganiso

• Ihlangabezana nezindinganiso zomhlaba wonke zokulinganiswa kwe-Parshall flume (isb., i-ASTM D1941, iziqondiso ze-ISO) kanye nezimfuneko zomthetho zokuphathwa kwemithombo yamanzi, ukuqapha imvelo, kanye nokubika ngokukhishwa kwamanzi ezimbonini.
