Esigabeni sokulinganisa ukugeleza kwemisele evulekile, ama-flowmeter ajwayelekile e-flume aqashelwa isikhathi eside njengesixazululo esithembekile nesingabizi kakhulu, esamukelwa kabanzi emikhakheni yokuqapha kamasipala, yezimboni, kanye neyezemvelo. Njengoba ebonakala ngesakhiwo sawo esilula, ukusebenza okuzinzile, kanye nokuhambisana nezindinganiso zokulinganisa zomhlaba wonke, lawa ma-flowmeter adlala indima ebalulekile ekulinganiseni ukugeleza kwamanzi nezinye izinto eziwuketshezi emiseleni evulekile njengemifula, imisele, kanye nezinhlelo zokukhipha amanzi. Lesi sihloko sihlola izinzuzo eziyinhloko, ukusetshenziswa okuhlukahlukene, izindlela zokukhetha ezibalulekile, kanye nezinto ezibalulekile zokulungisa ama-flowmeter ajwayelekile e-flume, siqokomisa indima yawo engenakuphindwa ekuphathweni kwemithombo yamanzi kanye nokulawulwa kwenqubo yezimboni.
Enye yezinzuzo eziyinhloko zama-flowmeter ajwayelekile e-flume itholakala ekunamatheleni kwawo kumiklamo ejwayelekile kanye nezindlela zokulinganisa ezivuthiwe. Ngokungafani namadivayisi okulinganisa ukugeleza okwenziwe ngokwezifiso, ama-flume ajwayelekile—njenge-Parshall flume, ama-Venturi flume, kanye nama-weirs angunxande—alandela imininingwane eyaziwayo emhlabeni wonke (isb., amazinga e-ISO, i-ASTM), eqinisekisa imiphumela yokulinganisa ehambisanayo nefanayo kuzo zonke izinhlelo zokusebenza ezahlukene. Lokhu kulinganisa kwenza kube lula ukulinganisa, kunciphisa amaphutha okulinganisa, futhi kusiza ukuthobela imithetho, okwenza kube ukukhetha okuthandwayo kwezimo ezidinga idatha yokugeleza enegunya, njengokuhlolwa komthelela wemvelo kanye namaphrojekthi okwabiwa kwemithombo yamanzi. Ngaphezu kwalokho, isakhiwo sabo esilula semishini, esingenazo izingxenye ezihambayo, sinciphisa ingozi yokuguguleka, ukuvaleka, noma ukwehluleka kwemishini, okuqinisekisa ukusebenza okuzinzile kwesikhathi eside ngisho nasezindaweni ezinzima ezinoketshezi olugcwele inhlabathi noma oluqukethe udoti.
Ububanzi bokusetshenziswa kwama-flowmeter ajwayelekile e-flume bubanzi, buhlanganisa imikhakha kamasipala, yezimboni, yezolimo, kanye neyezemvelo. Ekuphathweni kwamanzi kamasipala, asetshenziswa kabanzi ezitshalweni zokuhlanza indle ukuqapha ukugeleza okunethonya kanye nokuphuma kwamanzi, ahlinzeka ngedatha ebalulekile yokwenza ngcono izinqubo zokuhlanza nokuqinisekisa ukuhambisana nezindinganiso zokukhipha amanzi. Isibonelo, ama-flume e-Parshall, ngokunemba kwawo okuhle kokulinganisa ukugeleza kokubili ezimweni zokugeleza ezingaphansi kwesimo esibucayi kanye nezingaphezulu kwesimo esibucayi, avame ukufakwa eziteshini zokuhlanza indle ukulandelela ukusebenza kahle kokwelashwa nokuphatha izinsiza zamanzi ngempumelelo. Ezinhlelweni zokunisela kwezolimo, ama-flume ajwayelekile adlala indima ebalulekile ekulinganiseni ukusatshalaliswa kwamanzi, ukusiza abalimi ukwenza ngcono amashejuli okunisela, ukunciphisa imfucuza yamanzi, kanye nokuthuthukisa ukusebenza kahle kokusetshenziswa kwamanzi—okubaluleke kakhulu ezindaweni ezomile nezingenawo amanzi amaningi.
Ezindaweni zezimboni, kusetshenziswa ama-flowmeter ajwayelekile e-flume ukuqapha ukugeleza kwamanzi angcolile ezimbonini, amanzi okupholisa, kanye nokucubungula ukungcola. Izimboni ezifana nezezimayini, ukukhiqiza amaphepha, kanye nokucubungula ukudla, ezikhiqiza amanzi amaningi angcolile aqukethe izinhlayiya eziqinile noma izinto ezinamathelayo, ziyazuza ekuphikeleni kwama-flume ekuvalekeni kanye nezidingo eziphansi zokunakekelwa. Ekuqapheni imvelo, lawa ma-flowmeter asetshenziswa emifuleni, emachibini, nasezindaweni ezisogwini ukuze kulinganiswe amazinga okugeleza kwamanzi angaphezulu, kusekela ucwaningo lwe-hydrological, ukubikezela izikhukhula, kanye nokuhlolwa kwekhwalithi yamanzi. Isibonelo, ama-weirs angunxande avame ukufakwa emifuleni emincane ukuze kuqoqwe idatha yokugeleza kwesikhathi eside, esiza ekuvikeleni imvelo yasemanzini kanye nokuphathwa kwezinhlekelele ezihlobene namanzi.
Ukukhetha i-flowmeter ejwayelekile ye-flume kudinga ukucatshangelwa ngokucophelela izinto eziningana ezibalulekile ukuqinisekisa ukusebenza kahle. Okokuqala, uhlobo lwe-flume kumele luhambisane nezimo zesiteshi kanye nobubanzi bokugeleza. Ama-flume e-Parshall afanelekela amazinga amakhulu okugeleza kanye neziteshi ezibanzi, kuyilapho ama-flume e-Venturi efanelekile ukusetshenziswa okunesikhala esilinganiselwe kanye nezidingo zokunemba okuphezulu. Ngakolunye uhlangothi, ama-weirs angunxande akhethwa amazinga amancane kuya kwaphakathi okugeleza eziteshini ezincane. Okwesibili, usayizi we-flume kufanele ukhethwe ngokusekelwe kumazinga aphezulu naphansi okugeleza okulindelekile ukuqinisekisa ukuthi ukugeleza kuhlala ngaphakathi kobubanzi obuhle bokulinganisa be-flume, kugwenywe ukungalungi okubangelwa ukugeleza okunganele noma ukugcwala. Ngaphezu kwalokho, indawo yokufaka kumele icatshangelwe—ama-flume afakwe ezindaweni zangaphandle angadinga izinto ezingamelani nokugqwala (njengensimbi engagqwali noma i-fiberglass) ukuze amelane nesimo sezulu kanye nokugqwala kwamakhemikhali okuvela endaweni elinganisiwe.
Ukugcinwa okufanele kubalulekile ukuqinisekisa ukuthembeka kwesikhathi eside kanye nokunemba kwama-flowmeter ajwayelekile e-flume. Ukuhlolwa okuvamile kufanele kwenziwe ukuze kususwe inhlabathi, udoti, kanye nezitshalo zasemanzini ezingase ziqongelelane ku-flume, njengoba lokhu kungaphazamisa amaphethini okugeleza futhi kuthinte imiphumela yokulinganisa. Umphimbo we-flume, izindonga, kanye ne-weir crest kufanele kuhlolwe ukuthi azigugi, azinamonakalo, noma aziguquki, futhi noma yiziphi iziphambeko kufanele zilungiswe ngokushesha. Ukulinganisa, ngokuvumelana neziqondiso zomkhiqizi kanye nezindinganiso ezifanele, nakho kubalulekile—ukulinganisa ngezikhathi ezithile kuqinisekisa ukuthi i-flowmeter iyaqhubeka nokuhlinzeka ngedatha enembile, ikakhulukazi ngemva kokusetshenziswa isikhathi eside noma izinguquko ezibalulekile ezimpahleni ze-medium elinganisiwe.
Ekuphetheni, ama-flowmeter ajwayelekile e-flume avelele njengesixazululo esisebenzayo nesithembekile sokulinganisa ukugeleza kwesiteshi esivulekile, enikeza ukusebenza okujwayelekile, ukusetshenziswa okubanzi, kanye nezidingo zokunakekelwa okuphansi. Indima yawo ekuphathweni kwemithombo yamanzi, ukulawulwa kwenqubo yezimboni, kanye nokuqapha imvelo ibalulekile, inikela ekusetshenzisweni kwamanzi okuphumelelayo, ukuthobela imithetho, kanye nokuvikelwa kwemvelo. Njengoba ukunaka komhlaba wonke ekuphepheni kwamanzi kanye nentuthuko esimeme kukhula, ama-flowmeter ajwayelekile e-flume azoqhubeka nokuba yitshe lesisekelo lobuchwepheshe bokulinganisa ukugeleza, azivumelanise nezidingo zemboni ezishintshayo ngenkathi egcina izinzuzo zawo eziyinhloko zobulula, ukuthembeka, kanye nokunemba.
