Nzizi, senzira dzekuchengetedza nharaunda dzepasi rose nedzevanhu, dzinoda kutariswa nguva dzose uye kwakarurama kuti dzigadzirise matambudziko akadai semafashamo, kushomeka kwemvura, uye kusvibiswa. Maitiro ekutarisa kuyerera kwemvura akajairwa anowanzo kundikana munzvimbo dziri kure kana dzinochinja-chinja dzenzizi, nekuda kwemitengo yakakwira yekuisa uye kufamba kushoma. Mumamiriro ezvinhu aya, mita dzemvura dzinofambiswa dzinotakurika dzakabuda sezvishandiso zvinoshandura mutambo, zvichipa kuchinjika, nzwisiso yenguva chaiyo, uye kushanda zvakanaka kwekutarisa rwizi mumamiriro akasiyana-siyana. Kugona kwadzo kugadzirisa mamiriro akasiyana-siyana enzizi—kubva kunzizi dzakamanikana dzemakomo kusvika kunzizi dzakakura dzepasi—zvinoita kuti dzive dzinokosha kune vanoongorora mvura, vatariri vezvakatipoteredza, uye mapoka ezviwanikwa zvemvura pasi rese.
Pakati pema "portable open channel flowmeters" pane tekinoroji yakagadzirirwa kuyerwa panzvimbo yacho, isingapindi mvura. Matekinoroji maviri makuru anotsigira michina yakawanda: ultrasonic sensing uye electromagnetic induction. Mamodheru eUltrasonic anoshanda nekuburitsa mafungu eruzha parwizi; nguva inotora kuti mafungu abve pamusoro pemvura kana pasi perwizi inoshandiswa kuverenga kudzika kwemvura, nepo velocity inobva muDoppler shift yemafungu anoonekwa nezvikamu zvemvura zvinofamba. Iyi nzira yakanaka kune nzizi dzisina kudzika kusvika dzakadzika zvine mwero, sezvo dzichidzivirira kusangana zvakananga nemvura uye dzinoderedza kukanganiswa kwehupenyu hwemumvura. Ma "electromagnetic flowmeters", zvakasiyana, anovimba neMutemo waFaraday we "electromagnetic induction": kana mvura (chinhu chinofambisa mvura) ichiyerera nemumunda wemagineti unogadzirwa nemudziyo, voltage diki inokonzerwa. Hukuru hwevoltage iyi hunoenderana nekumhanya kwemvura, zvichibvumira kuyerwa kwakarurama kunyangwe munzizi dzine madhaka kana sediment - dzinowanikwa munzvimbo dzine mvura inoyerera kana kukurwa kwevhu. Matekinoroji ese ari maviri akabatanidzwa mumayuniti madiki, anoshandiswa nemabhatiri, zvichibvumira mapoka emunda kuti agadzire uye ashandise mukati memaminitsi, pasina kudiwa kwemidziyo inorema kana zvivakwa zvechigarire.
Zvakanakira zvema "portable flowmeters" mukushandiswa kwerwizi zvakasiyana uye zvine simba, zvichitanga nekufamba kusingaenzaniswi uye kuchinjika. Kusiyana nemasisitimu akagadziriswa, ayo anongogumira kunzvimbo dzakaiswa kare, zvishandiso zvinotakurika zvinogona kutakurwa kuenda kune chero chikamu cherwizi—ingava rwizi rwuri kure musango kana nzvimbo inokurumidza kusviba murwizi rwemaguta. Semuenzaniso, panguva yekuongororwa mushure medutu, nyanzvi dzemvura dzinogona kukurumidza kuisa ma "portable metres" akawanda pahurefu hwerwizi kuti dziongorore kusiyana kwekuyerera kwemvura, dzichiona nzvimbo dzine sediment yakawanda kana "channel erosion" iyo ma "fixed sensors" angasashande. Kuchinjika uku kwakakoshawo pakutarisa nzizi dzenguva pfupi (dzinooma nemwaka), uko kuiswa kwekusingaperi kungave kusingashandi uye kusingashande.
Kuunganidzwa kwedata munguva chaiyo ndeimwe bhenefiti huru, kugadzirisa dambudziko rekukurumidzira kwemabasa mazhinji ekutarisira rwizi. Ma "flowmeter" anotakurika anoratidza mwero wekuyerera kwemvura, kudzika kwemvura, uye kumhanya ipapo ipapo pama "built-in screens" kana kuburikidza nema "Bluetooth-connected mobile apps". Kumhanya uku kwakakosha pakurwisa mafashamo: kana mvura yakawanda ichinaya ichityisidzira nharaunda, mapoka emumunda anogona kushandisa ma "portable metres" kuyera kukwira kwehuwandu hwemvura munguva chaiyo, zvichipa vakuru vemunharaunda data rekupa nyevero dzekubuda panguva chaiyo. Saizvozvowo, panguva yekusanaya kwemvura, data rekuyerera kwemvura munguva chaiyo rinobatsira vatariri vemvura kugadzirisa miganhu yekubviswa kwemvura mukurima kana kushandiswa kwemaguta, vachiona kuti kugoverwa kwemvura kwakachengeteka pasina kukuvadza nharaunda dzemurwizi.
Kushanda zvakanaka kwemari kunoita kuti kukosha kwema "portable flowmeters" kuwedzere kusimba. Nzvimbo dzekutarisa rwizi dzakagadziriswa dzinogona kudhura makumi ezviuru zvemadhora kuisa nekugadzirisa, kusanganisira mari yekuisa nheyo dzekongiri, magetsi, uye kuongororwa nguva nenguva panzvimbo yacho. Mhando dzinotakurika, zvakasiyana, dzine mitengo yakaderera yekutanga (kazhinji chikamu chema "fixed systems") uye zvinodiwa zvishoma zvekugadzirisa - zvakawanda zvinoda kungotsiviwa kwemabhatiri nguva nenguva uye kugadziriswa kwemasensa. Kune masangano madiki ezvakatipoteredza kana hurumende dzemunharaunda dzine bhajeti shoma, mukana uyu wekutengesa rwizi nguva dzose unoita kuti kuongororwa kwerwizi kuenderane nekuitika kekutanga.
Mukuita, mita dzemvura dzinofambiswa dzinofambiswa dzinotsigira mabasa matatu akakosha ane chekuita nerwizi: tsvakiridzo yemvura, manejimendi yemvura, uye kutarisa nharaunda. Mutsvakiridzo yemvura, masayendisiti anoashandisa kudzidza maitiro ekuyerera kwemwaka—semuenzaniso, kutevera kuti kunyunguduka kwechando munzizi dzemakomo kunokanganisa sei kubuda kwemvura pasi perwizi. Ruzivo urwu runobatsira kunatsiridza mamodheru ekufanotaura mafashamo uye kuvandudza kunzwisisa kwemhedzisiro yekushanduka kwemamiriro ekunze panzira dzenzizi. Mukutarisira zviwanikwa zvemvura, mita dzemvura dzinofambiswa dzinovimbisa kugoverwa kwemvura kwakaringana: munzvimbo dzine varimi vakawanda vanovimba nerwizi rumwe chete pakudiridza, mita dzinosimbisa kuti hapana mushandisi anopfuura huwandu hwemvura hwakatarwa, kudzivirira kusawirirana uye kuderedza marara. Pakutarisa nharaunda, dzinoita basa guru mukupindura kusvibiswa: kana kudonha kwemakemikari kukaitika, mita dzemvura dzinoyera mwero wekubuda kwemvura murwizi, zvichibvumira vane masimba kuverenga huwandu hwese hwemvura yakasvibiswa uye kugadzira nzira dzakanangana dzekuchenesa. Dzinotarisawo hutano hwezvakatipoteredza nekutevera mwero wekuyerera kwakakosha kune mhuka dzemumvura—semuenzaniso, kuona kuti kuyerera kushoma munzizi kuchengetedza nzvimbo dzekuberekera hove.
Pasinei nezvakanakira, ma "flowmeter" anotakurika anosangana nematambudziko mumamiriro emvura akaoma. Kuyerera kwemvura kunovhuvhuta (kunowanzoonekwa munzizi dzinofamba nekukurumidza mumakomo) kunogona kukanganisa kuverenga kwema sensor, nepo kuwanda kwemvura mumakomo kuchigona kuvhara ma "electromagnetic sensors" nekufamba kwenguva. Kuti vagadzirise matambudziko aya, vagadziri vakagadzira mhinduro dzakasimba: ma "ultrasonic meters" iye zvino anosanganisira ma "turbulence-correction algorithms" ekusefa data risingachinji, uye ma "electromagnetic sensors" ane ma "coatings" anodzivirira kupfekwa kuti adzinge mvura mu "sediment". Pamusoro pezvo, michina yakawanda inoongororwa kuti inoshanda seisingapindi mvura uye isingapfuuri guruva (kazhinji IP67 kana kupfuura), ichivimbisa kugara kwenguva refu munzvimbo dzine mvura yakawanda kana dzine matope.
Mukupedzisa, ma "portable open channel flowmeters" akachinja kutarisa kwerwizi nekubatanidza kufamba, kumhanya, uye kukwanisika kutenga. Anovhara mipata inosiyiwa nemasisitimu akagadziriswa, achigonesa kuunganidzwa kwedata munzvimbo dziri kure kana dzinochinja-chinja dzerwizi uye achipa simba kune vane chekuita nekuita sarudzo dzine ruzivo nezvenjodzi yemafashamo, kugoverwa kwemvura, uye kuchengetedzwa kwezvakatipoteredza. Sezvo tekinoroji ichifambira mberi—nemamodheru emangwana angangobatanidza kubatana kweIoT kwekugovana data panguva chaiyo pakati pemapoka—basa ravo mukutarisira nzizi dzinogara kwenguva refu richangokura. Kune chero ani zvake ane basa rekuchengetedza nzizi, maturusi aya anotakurika haasisiri epamusoro asi chinhu chakakosha, achivimbisa kuti masisitimu emvura yakachena epasi redu anotariswa, anodzivirirwa, uye anotariswa kwezvizvarwa zvinotevera.
