1. Yenzelwe iiHydraulics zeParshall Flume

• Ukusebenzisana noyilo lwe-flume: Ii-flume ze-Parshall zenzelwe ukuguqula isantya sokuhamba kwamanzi sibe kukunyuka kwamanzi okulinganiselweyo kwicandelo elithile "lomqala". Iimitha ze-ultrasonic zilinganisa ngokuchanekileyo eli nqanaba libalulekileyo (ngesiqhelo kwicandelo eliphezulu lomqala okanye lokusondela kwe-flume) kwaye zisebenzisa iifomyula zokukhupha i-flume ze-Parshall ezicwangcisiweyo kwangaphambili ukubala izinga lokuhamba kwamanzi.
• Iiparamitha ze-flume ezilayishwe kwangaphambili: Iimodeli ezininzi ziquka iidathabheyisi ezakhelwe ngaphakathi zobukhulu be-flume yeParshall eqhelekileyo (umz., imiqala eyi-1-intshi ukuya kwi-50-foot) kunye nee-coefficients zazo zokukhupha ezihambelanayo, zisusa ukufakwa kwefomyula ngesandla kwaye ziqinisekisa ukuthotyelwa kwemigangatho ye-hydraulic (umz., i-ASTM D1941).

2. Umlinganiselo Ongaphazamisiyo, Ongenampembelelo Iphantsi

• Ukungadibani nokuhamba kwamanzi: Izinzwa ze-Ultrasonic zifakelwe ngaphezulu kwecandelo lokulinganisa i-Parshall flume (akukho zinto zingaphantsi kwamanzi), zithintela ukuphazamiseka kwiipateni zokuhamba kwamanzi ezibalulekileyo ze-flume. Oku kubalulekile kuba ii-Parshall flumes zixhomekeke ekuhambeni kwamanzi okungaphazamisekiyo ukuze zigcine ukuchaneka.
• Akukho mngcipheko wokuvaleka: Ngokungafaniyo nee-transducers zoxinzelelo okanye iipleyiti ze-weir, ii-sensors ze-ultrasonic azichaphazeleki yi-sediment, inkunkuma, okanye amasuntswana adadayo axhaphakileyo kumanzi amdaka, ukunkcenkceshela, okanye ukuhamba kwamanzi kwimizi-mveliso—izinto ezibalulekileyo kwii-flumes ezisetyenziswa kumanzi angcolileyo.

3. Ukuchaneka Okuphezulu Kwiimeko Zokuhamba Okubalulekileyo

• Ukuchonga inqanaba ngokuchanekileyo: Iiflume zeParshall zifuna ukulinganiswa kwenqanaba ngokuchanekileyo kwiindawo ezithile (umz., indawo yokulinganisa ephezulu) ukuze kubalwe ukuhamba kwamanzi. Iisensa ze-Ultrasonic zibonelela ngokuchaneka kwenqanaba ukusuka ku-±0.1% ukuya ku-±0.5% yesikali esipheleleyo, nokuba kukho ukuxinana okuncinci komphezulu okanye isenzo samaza kwiflume.
• Ukuthembeka kokubala ukuhamba: Isebenzisa i-Parshall flume's empirical discharge equation Q=C×Hn (apho u-Q = isantya sokuhamba, u-H = intloko elinganisiweyo, u-C = i-coefficient, u-n = i-exponent), edityaniswe nedatha yenqanaba le-ultrasonic ukuqinisekisa ukuba iziphumo ziyalandeleka ngokwemigangatho yoshishino.

4. Ukuziqhelanisa nobungakanani kunye nokusetyenziswa kweParshall Flume

• Ihambelana nazo zonke iisayizi ezisemgangathweni: Isebenza ngee-Parshall flumes ezincinci (zelebhu) ukuya kwezinkulu (zemizi-mveliso/zezolimo), ukusuka kwii-mini-flumes (umphimbo we-intshi enye) ukuya kwii-flumes ezinkulu zemilambo okanye imijelo (umphimbo weenyawo ezingama-50).
• Iphatha imiqolo eyahlukeneyo yokuhamba kwamanzi: Ii-Parshall flumes zenzelwe imiqolo ethile yokuhamba kwamanzi (umz., 0.01 ukuya kwi-300+ cfs), kwaye iimitha ze-ultrasonic zihambelana nezi zigaba ngokulinganisa utshintsho oluhambelanayo lwamanqanaba, ukuqinisekisa ukuchaneka kokubini ukuhamba kwamanzi okuphantsi nokuphakama.

5. Ukusebenza Okuqinileyo Kwiindawo Ezithile Ezijongene Neflume

• Ukuxhathisa ukuphazamiseka okunxulumene neflume: Ukulungiswa kwesignali okuphucukileyo kucoca ingxolo evela ekutshizeni, kwifoam, okanye kwiibhamuza zomoya—ezixhaphakileyo kwiiflume zeParshall ngenxa yokukhawuleziswa kokuhamba kwamanzi emqaleni.
• Imozulu nokuqina kokusingqongileyo: Izinzwa ezinereyithingi ye-IP65/IP66/IP67 ziyamelana nemvula, ukufuma, kunye nobushushu obugqithisileyo, nto leyo ebalulekileyo kwiiflume zangaphandle kwiindawo zolimo, amanzi amdaka, okanye iindawo zamanzi emvula.
• Uyilo oluchasene nokuphazamiseka: Lunciphisa ukufundwa okungachanekanga okuvela elangeni, ukukhanya kweendonga ze-flume, okanye inkunkuma edada phezu kwamanzi.

6. Ukufakwa okulula kunye nokulinganisa

• Ukufakelwa okulula: Iisensors zifakelwa ngaphezulu kwenqaku lokulinganisa i-flume (ngesiqhelo kwi-bracket okanye kwi-crossbar) kwaye akukho msebenzi mkhulu wokwakha, nto leyo ethintela utshintsho kwisakhiwo se-flume.
• Ukulinganisa ngokukhawuleza: Ilungiselelwe kwangaphambili iijometri ze-Parshall flume, inciphisa ixesha lokuseta. Abasebenzisi banokuqinisekisa ukuchaneka ngokujonga amanqanaba ngokulula kwizinga lokuhamba kwamanzi elaziwayo.

7. Idatha kunye noHlanganiso lweXesha langempela

• Ukubeka esweni rhoqo: Ibonelela ngesantya sokuhamba kwamanzi ngexesha langempela, inqanaba lamanzi, kunye nedatha yendlela esetyenziswa ngayo, eboniswa kwindawo yakho kwiscreen okanye edluliselwe kwi-SCADA, ii-PLC, okanye amaqonga efu ngeModbus, 4G/5G, Wi-Fi, okanye iLoRa.
• Ukugcinwa kwedatha: Kugcina idatha yokuhamba kwembali (umz., umyinge weyure/wemihla ngemihla, ukuhamba kwencopho) ukuze kuxelwe ukuthotyelwa kwemithetho, ucwangciso lokunkcenkceshela, okanye ukulungiswa konyango lwamanzi amdaka.
• Isilumkiso: Izilumkiso ezilungisekayo zamanqanaba aphezulu/aphantsi (ezibonisa ukuvaleka kweflume okanye ukugcwala kwamanzi) okanye ukungasebenzi kakuhle kwesensor, okuvumela ukugcinwa ngokukhawuleza.

8. Ukugcinwa Okuphantsi kunye Nobude Bexesha Elide

• Akukho zixhobo zishukumayo: Iphelisa ukuguguleka kwezinto ezisetyenziswa ngoomatshini, inciphisa ixesha lokungasebenzi. Ukugcinwa rhoqo kunqunyelwe ekucoceni i-sensor rhoqo (ukususa uthuli okanye iintambo zesigcawu) kunye nokuhlolwa kokulinganisa.
• Ulwakhiwo oluhlala ixesha elide: Iisensors kunye neetransmitter zakhiwe ukuze zikwazi ukumelana neemeko ezinzima, ziqinisekisa ubomi benkonzo ende nokuba kungaphandle okanye kwimizi-mveliso.

9. Iindleko ezingabizi kakhulu kwiiNkqubo zeFlume

• Ixabiso lilonke eliphantsi lobunini xa lithelekiswa neemitha ezingenelelayo: Akukho mfuneko yee-sensors ezingaphantsi kwamanzi (ezifuna ukutshintshwa rhoqo ngenxa yokugqwala okanye ukuvaleka) okanye utshintsho lwe-flume.
• Kunciphisa iindleko zomsebenzi: Ukufakela okulula kunye nokugcinwa okuncinci kunciphisa iindleko zokusebenza ngokuhamba kwexesha.

10. Ukuthobela iMigangatho

• Ihlangabezana nemigangatho yamazwe ngamazwe yokulinganisa i-Parshall flume (umz., i-ASTM D1941, izikhokelo ze-ISO) kunye neemfuno zomthetho zolawulo lwemithombo yamanzi, ukujonga okusingqongileyo, kunye nengxelo yokukhupha amanzi kwimizi-mveliso.
