Mukayang'anira kutayira madzi otayira, kukonza zimbudzi kapena ntchito zothirira, kusankha mita yoyezera madzi otseguka bwino kumatsimikizira molondola muyeso, kutsatira malamulo, komanso ntchito yokonza nthawi yayitali. Mainjiniya ambiri amanyalanyaza mfundo imodzi yofunika: palibe mita yoyezera madzi otseguka yomwe imagwira ntchito bwino pamalo aliwonse. Kugwira ntchito kwake kumadalira kwambiri ngati ikugwirizana ndi kapangidwe kake ka madzi otayira madzi kapena madzi otayira madzi. Chifukwa chake funso lofunika kwambiri ndilakuti: ndi mita yoyezera madzi otseguka iti yomwe ikugwirizana ndi momwe madzi anu otayira madzi kapena madzi otayira madzi alili?
Mawero ndi ma flume ndi zida zoyezera zazikulu zomwe zimamanga ubale wokhazikika pakati pa kuchuluka kwa madzi ndi kuchuluka kwa madzi. Mawero, kuphatikizapo mawero a triangular V-notch ndi mawero a rectangle, amapanga chotchinga kudutsa njira yonse, zomwe zimapangitsa kuti madzi atulukire pa ma notches olinganizidwa. Mawero a V-notch amapereka kukhudzidwa kwabwino kwambiri pazochitika zochepa zamadzimadzi, zomwe zimagwiritsidwa ntchito kwambiri potulutsa madzi ang'onoang'ono komanso njira zoyeretsera madzi m'ma laboratories. Komabe, mawero amapanga maiwe akumtunda komwe matope, matope ndi zinyalala zoyandama zimasonkhana mosavuta. Kuyeretsa pafupipafupi kumakhala kofunikira, apo ayi zinthu zomwe zili m'madzi zimasokoneza kuwerenga kwa madzi ndikupanga deta yosadalirika ya madzi.
Ma Flume, monga flume yotchuka padziko lonse ya Parshall, amatseka magawo a njira kuti apititse patsogolo kuyenda kwa madzi kufika pa liwiro lofunikira mkati mwa gawo la mmero. Chifukwa cha kuthamanga kwa madzi mofulumira, ma flume ali ndi mphamvu yodziyeretsa yokha komanso amapewa kusonkhanitsa zinyalala. Izi zimapangitsa kuti akhale njira yabwino kwambiri yogwiritsira ntchito zinyalala zosaphika, zinyalala zamafakitale komanso mchenga wonyamula madzi kapena tinthu tating'onoting'ono. Poyerekeza ndi makoma a matabwa, ma flume amapanga kutayika kwa mitu yotsika ndipo amalekerera kumiza pang'ono pansi pa madzi, komabe amafuna zomangamanga zolondola komanso kukhazikika kolimba kuti zitsimikizire kulondola kolondola.
Ma ultrasound open channel flow meter amakono amawerengera kuchuluka kwa madzi poyesa kuya kwa madzi nthawi yeniyeni ndikugwiritsa ntchito ma hydraulic formulas omwe adakonzedwa kale pama weirs kapena flumes. Komabe, si ma transmitter onse omwe amathandizira laibulale yonse ya ma weir flume equation. Zipangizo zina zotsika mtengo zimangopereka ma profiles ochepa a channel. Ngati mulumikiza mita popanda magawo olondola omangidwa mkati ku Parshall flume kapena triangular weir, mudzapeza zotsatira zoyenda bwino koma zolakwika kwathunthu, ngakhale pamene ma level readings akuwoneka abwinobwino. Ichi ndi vuto lofala kwambiri pakugula munda.
Kupatula kugwirizana kwa mbiri, muyenera kuwunika momwe malo ogwirira ntchito alili. Kuti madzi oyera atuluke ndi madzi olimba pang'ono, choyezera madzi chomwe chimakonzedwa kuti chigwiritsidwe ntchito pa mipanda ya V-notch chingapereke zotsatira zokhazikika komanso zotsika mtengo. Pa zimbudzi za m'matauni okhala ndi zinyalala zambiri, sankhani choyezera chomwe chikugwirizana bwino ndi ma data a Parshall flume, ndikutsimikizira magwiridwe antchito oletsa kusokoneza nthunzi, kupopera madzi ndi kugwedezeka kwa pamwamba pamalopo. Ntchito zolumikizirana ziyeneranso kusamalidwa. Zotulutsa za M-Bus, Modbus-RTU kapena HART zimalola kukweza deta yakutali kuti ipereke malipoti okhudzana ndi kutsata malamulo a chilengedwe, kuchotsa zolakwika zojambulira pamanja.
Zofunikira pakukhazikitsa sizinganyalanyazidwenso. Makoma ndi ma flume onse amafunikira magawo okwanira owongoka a m'mwamba ndi pansi pa mtsinje kuti akhazikitse kayendedwe ka madzi. Ngakhale mita yoyezera madzi yotseguka bwino kwambiri idzavutika ndi kusinthasintha kolondola ngati ntchito ya zomangamanga ilephera kukwaniritsa zofunikira. Opereka zida odalirika amapereka zikalata zonse zaukadaulo, kutsogolera mainjiniya kudzera pamalo oyika masensa, kutalika kochepa kwa chitoliro chowongoka komanso njira zoyezera. Thandizo la patali nthawi yake limachepetsanso nthawi yogwira ntchito m'malo a m'matauni ndi m'mafakitale.
Ziphaso ziyeneranso kuganiziridwa pa ntchito zapadziko lonse lapansi. Kuvomerezedwa kwa Metrology kumaonetsetsa kuti deta yoyezedwa ya kayendedwe ka madzi ndi yovomerezeka pa malipoti ovomerezeka azachilengedwe. Pewani kusankha mita yotsika mtengo yosavomerezeka, chifukwa kulephera kuvomereza ntchito kumabweretsa kutayika kwakukulu kuposa ndalama zoyambira zosungira zida.
Mwachidule, kufananiza mita yanu yoyendetsera madzi yotseguka ndi kapangidwe kake ka chitsulo chosungira madzi kapena chitsulo chosungira madzi ndi chinthu chofunikira kwambiri poyesa madzi odalirika. Tsimikizani ma profiles a hydraulic omwe ali mkati, mawonekedwe apakati, zoletsa zoyikamo ndi ma interface olumikizirana ofunikira musanagule. Ngati mugawana zambiri kuphatikizapo mtundu wa chitsulo chosungira madzi kapena chitsulo chosungira madzi, kukula kwa njira, malo apakati ndi kuchuluka kwa madzi otuluka, akatswiri aukadaulo angakulangizeni njira yoyenera kwambiri yoyendetsera madzi otseguka pa njira yanu yogwiritsira ntchito chitsulocho.
