Uma uphatha ukuqapha ukukhishwa kwamanzi amdaka, ukwelashwa kwendle noma amaphrojekthi okunisela, ukukhetha imitha yokugeleza yesiteshi esivulekile efanelekile kunquma ngqo ukunemba kokulinganisa, ukuthobela imithetho kanye nomsebenzi wokulungisa wesikhathi eside. Onjiniyela abaningi bayayishaya indiva iphuzu elilodwa elibalulekile: ayikho imitha yokugeleza yesiteshi esivulekile esebenza kahle kuyo yonke indawo. Ukusebenza kwayo kuncike kakhulu ekutheni ihambisana yini nesakhiwo sakho se-weir noma se-flume hydraulic. Ngakho-ke umbuzo obalulekile usalokhu: iyiphi imitha yokugeleza yesiteshi esivulekile efanelana nesimo sakho sesiteshi se-weir noma se-flume?
Ama-Weirs nama-flume yizinto zokulinganisa eziyinhloko ezakha ubudlelwano obuqinile bezibalo phakathi kwezinga lamanzi kanye nesivinini sokugeleza. Ama-Weirs, kufaka phakathi ama-weirs angunxantathu angu-V kanye nama-weirs angunxande, adala isithiyo ngaphesheya kwesiteshi, okuphoqa amanzi ukuthi achitheke phezu kwama-notches alinganisiwe. Ama-weirs angunxande angu-V anikeza ukuzwela okuhle kakhulu ezimweni zokugeleza okuphansi, okusetshenziswa kabanzi ezindaweni zokukhipha amanzi amdaka ezincane kanye nezinhlelo zokwelashwa kwelebhu. Noma kunjalo, ama-weirs akha amachibi aphezulu lapho indle, udaka kanye nodoti oluntantayo luqongelela khona kalula. Ukuhlanza njalo kuba yimpoqo, ngaphandle kwalokho ama-deposit azophazamisa ukufundwa kwezinga lamanzi futhi akhiqize idatha yokugeleza engathembekile.
Ama-Flume, njenge-Parshall flume edumile emhlabeni jikelele, anciphisa izigaba zemifudlana ukuze asheshise ukugeleza kuye esivivinyweni esibucayi ngaphakathi kwesigaba somphimbo. Ngenxa yesivinini sokugeleza esisheshayo, ama-flume anekhono lokuzihlanza futhi amelane nokwakheka kwendle. Lokho kuwenza abe yindlela ekhethwayo yendle eluhlaza, ukungcola kwezimboni kanye nesihlabathi esithwala amanzi noma izinhlayiya eziqinile. Uma kuqhathaniswa nama-weirs, ama-flume akhiqiza ukulahlekelwa kwekhanda eliphansi futhi abekezelela ukucwiliswa okuphakathi nendawo, kodwa adinga ukwakhiwa okuqondile kanye nokulungiswa okuqinile kokufakwa ukuqinisekisa ukunemba okulinganiselwe.
Amamitha okugeleza eziteshini ezivulekile ze-ultrasonic zanamuhla abala ivolumu yokugeleza ngokulinganisa ukujula kwamanzi ngesikhathi sangempela nokusebenzisa amafomula e-hydraulic ahlelwe kusengaphambili kuma-weirs noma ama-flumes. Kodwa-ke, akuwona wonke ama-transmitter asekela umtapo wolwazi ogcwele wezibalo ze-weir-flume. Amanye amadivayisi ashibhile anikeza amaphrofayili eziteshi alinganiselwe kuphela. Uma uxhuma imitha ngaphandle kwamapharamitha afanele akhelwe ngaphakathi ku-Parshall flume noma i-triangular weir, uzothola imiphumela yokugeleza ehambisanayo kodwa engalungile ngokuphelele, noma ngabe ukufundwa kwamazinga kubukeka kujwayelekile. Lokhu kuyisithiyo esivamile ekuthengweni kwensimu.
Ngaphandle kokuhambisana kwephrofayili, kufanele uhlole izimo zangempela zokusebenza endaweni. Ukuze kukhishwe amanzi ahlanzekile anokuqukethwe okuqinile okuphansi, imitha yokugeleza ehlelwe izindonga ze-V notch inganikeza imiphumela yokulinganisa ezinzile nengabizi kakhulu. Kumanzi angcolile kamasipala anokungcola okukhulu, khetha imitha ehambisana ngokugcwele namasethi edatha e-Parshall flume, bese uqinisekisa ukusebenza kokungaphazanyiswa komusi, ukufuthwa kwamanzi kanye nokuxokozela komhlaba endaweni. Imisebenzi yokuxhumana nayo ifanelwe ukunakwa. Imiphumela ye-M Bus, i-Modbus RTU noma i-HART ivumela ukulayishwa kwedatha okude ukuze kubikwe ukuhambisana nemvelo, kususwe amaphutha okurekhoda ngesandla.
Izidingo zokufakwa nazo azinakwa. Zombili izigodi kanye nama-flume adinga izingxenye ezanele zesiteshi esiqondile phezulu nangezansi komfula ukuze kuqiniswe amaphethini okugeleza. Ngisho nemitha yokugeleza yesiteshi esivulekile esebenza kahle kakhulu izobhekana nokuguguleka kokunemba uma umsebenzi wokwakha wehluleka ukuhlangabezana nezimfuneko. Abaphakeli bezinsimbi abathembekile banikeza imibhalo yobuchwepheshe ephelele, beqondisa onjiniyela ngesikhundla sokufaka inzwa, ubude obuncane bepayipi eliqondile kanye nezinqubo zokulinganisa. Ukusekelwa okukude ngesikhathi esifanele kunciphisa kakhulu isikhathi sokungasebenzi kwezindawo zikamasipala nezezimboni.
Isitifiketi kufanele sicatshangelwe namaphrojekthi aphesheya. Ukuvunyelwa kwe-Metrology kuqinisekisa ukuthi idatha yokugeleza elinganisiwe iyamukeleka emibikweni esemthethweni yezemvelo. Gwema ukukhetha amamitha ashibhile angaqinisekisiwe, njengoba ukwehluleka kokwamukelwa kwephrojekthi kuzoletha ukulahlekelwa okukhulu kakhulu kunokonga kwemishini kokuqala.
Ngamafuphi, ukufanisa imitha yakho yokugeleza yesiteshi esivulekile nesakhiwo sakho esikhona se-weir noma i-flume kuyisici esibalulekile sokulinganisa ukugeleza okuthembekile. Qinisekisa amaphrofayili e-hydraulic akhelwe ngaphakathi, izici eziphakathi nendawo, imikhawulo yokufaka kanye nezixhumanisi zokuxhumana ezidingekayo ngaphambi kokuthenga. Uma wabelana ngemininingwane kufaka phakathi uhlobo lwe-weir noma i-flume, usayizi wesiteshi, indawo ephakathi nendawo kanye nobubanzi bokugeleza, ochwepheshe bezobuchwepheshe bangancoma isisombululo semitha yokugeleza yesiteshi esivulekile esifanele kakhulu sohlelo lwakho lokusebenza oluthile lwesiteshi.
