Njengendawo ebalulekileyo yokutyala isityalo, ukunkcenkceshela kunye nolawulo lwenqanaba lamanzi kumasimi e-paddy kudlala indima ebalulekileyo kumgangatho kunye nesivuno semveliso yerayisi. Ngophuhliso lwezolimo lwanamhlanje, ukusetyenziswa ngokufanelekileyo kunye nokulawulwa kobutyebi bamanzi kuye kwaba ngumsebenzi obalulekileyo. Imitha yenqanaba le-Capacitive ithe ngokuthe ngcembe ibe lolona khetho lufanelekileyo lokujongwa kwinqanaba lamanzi ethafeni ngenxa yokuchaneka kwayo okuphezulu, ukuzinza kunye nokuqina. Eli nqaku liza kuxubusha umgaqo wokusebenza, iingenelo zesicelo, iimeko eziphathekayo kunye nethemba lophuhliso lwemitha yezinga le-capacitive kwiinkalo ze-paddy.
1. Umgaqo wokusebenza wemitha yenqanaba le-capacitive
Umgaqo wokusebenza wemitha yenqanaba le-capacitive isekelwe ekutshintsheni i-capacitance. Xa umgangatho we-liquid we-liquid medium utshintsho, i-dielectric constant constant ye-liquid ichaphazela i-capacitance ye-capacitor, ngaloo ndlela iqonda umlinganiselo wezinga le-liquid. Amanyathelo athile ngala alandelayo:
Isakhiwo se-Capacitor: Imitha yezinga le-Capacitive idla ngokuba nee-electrode ezimbini, enye yazo i-probe kwaye enye idla ngokuba yintambo yomhlaba okanye isitya ngokwaso.
Ukutshintsha rhoqo kwe-Dielectric: Ukutshintsha kwinqanaba lolwelo kuya kubangela utshintsho oluphakathi phakathi kwee-electrodes. Xa inqanaba le-liquid liphakama okanye liwa, i-dielectric constant ejikeleze i-electrode (efana ne-dielectric constant of air yi-1, kunye ne-dielectric constant of water malunga ne-80) utshintsho.
Umlinganiselo weCapacitance: Imitha yenqanaba ibeka iliso ngokuqhubekayo utshintsho lwe-capacitance ngokusebenzisa isiphaluka, kwaye emva koko iguqulela kwisiphumo samanani kwinqanaba le-liquid.
Isiphumo soMqondiso: Imitha yomgangatho ihambisa ngokubanzi ixabiso lomgangatho wolwelo olulinganisiweyo kwisixokelelwano solawulo okanye isixhobo sokubonisa ngomqondiso we-analog (efana ne-4-20mA) okanye isignali yedijithali (efana ne-RS485).
2. Iimpawu zemitha yenqanaba le-capacitive kumabala e-paddy
Uyilo kunye nokusetyenziswa kwemitha yenqanaba le-capacitive kumasimi e-paddy kuthathela ingqalelo ubume bemeko yendawo ye-paddy. Iimpawu zayo zibonakaliswa ikakhulu kule miba ilandelayo:
Ikhono elinamandla lokuchasana nokuphazamiseka: Indalo engqongileyo kwintsimi ye-paddy iyinkimbinkimbi, kwaye i-capacitive level meter ngokuqhelekileyo isebenzisa ii-circuits ezichasayo xa kuyilwa ukuqinisekisa ukuzinza okuphezulu phantsi komswakama kunye nokutshintsha kwemozulu.
Umlinganiselo ophezulu wokuchaneka: Imitha yezinga le-capacitive inokubonelela ngokuchaneka komgangatho wamanzi omgangatho we-millimeter, ofanelekileyo kulawulo oluhle lokunkcenkceshela kunye nemithombo yamanzi.
Izinto ezikwaziyo ukumelana nokutyiwa: Kumasimi erayisi, imitha yomgangatho kufuneka ixhathise umhlwa emanzini, emhlabeni kunye nezinye iikhemikhali, ngoko ke iprobe idla ngokwenziwa ngezinto ezikwaziyo ukugilana (njengentsimbi engatyiwa, iplastiki, njl. njl.).
Kulula ukuyifaka kunye nokugcina: Imitha yezinga le-capacitive ilula kuyilo, ayithathi indawo eninzi yokufakela, kwaye ilula ukuyigcina, iyenze ilungele ukusetyenziswa kwiindawo ezisemaphandleni.
Umsebenzi wokubeka iliso kude: Uninzi lweemitha zenqanaba le-capacitive kumasimi erayisi axhotyiswe ngeemodyuli zonxibelelwano ezingenazingcingo, ezinokuqonda ukubeka iliso kude kunye nolawulo lwedatha, kunye nokuphucula inqanaba lobukrelekrele bolawulo lokunkcenkceshela.
3. Ukusetyenziswa kweenzuzo ze-capacitive level meters kumasimi erayisi
Ulawulo lobutyebi bamanzi: Ngokubeka iliso ngexesha lokwenyani lomgangatho wamanzi kumasimi erayisi, amafama anokugweba ngokuchanekileyo iimfuno zokunkcenkceshela, ukunciphisa inkcitho yamanzi, nokuphucula ukusebenza kakuhle kwamanzi.
Yandisa izivuno zezityalo: Ulawulo lomgangatho wamanzi ngokwenzululwazi lunokukhuthaza ukukhula nophuhliso lwerayisi, luqinisekise unikezelo lwamanzi olwaneleyo, kwaye luthintele ukuncipha kwemveliso okubangelwa kukunqongophala kwamanzi okanye ukufumba kwamanzi.
Ulimo olukrelekrele: Ukudibanisa itekhnoloji ye-sensor kunye ne-Intanethi yeZinto, i-capacitive level metres inokudityaniswa kwinkqubo yolawulo lwezolimo jikelele ukwenza isisombululo sokunkcenkceshela esikrelekrele kunye nokufezekisa ulimo oluchanekileyo.
Ukwenziwa kwezigqibo ezixhaswa yidatha: Ngokubeka iliso ixesha elide kunye nohlalutyo lwedatha yenqanaba lamanzi, amafama kunye nabaphathi bezolimo banokwenza izigqibo zenzululwazi, basebenzise iindlela zokulima kunye nexesha, kwaye baphucule umgangatho wolawulo lwezolimo.
4. Amatyala okwenene
I-Case 1: Ukulawulwa kwenqanaba lamanzi kwintsimi yerayisi eVietnam
Kwintsimi yerayisi eVietnam, amafama ngokwesiko axhomekeke kumgangatho wamanzi otshekishwayo ngokunkcenkceshela. Le ndlela ayisebenzi kwaye ithande ukuba neempazamo ngenxa yesigwebo se-subjective. Ukuze kuphuculwe ukusebenza kakuhle kokusetyenziswa kobutyebi bamanzi, amafama agqibe ekubeni azise i-capacitive level meters njengezixhobo zokuhlola umgangatho wamanzi.
Emva kokufaka i-capacitive level meter, abalimi banokubeka iliso kwinqanaba lamanzi kwintsimi yerayisi ngexesha langempela kwaye bafumane idatha yezinga lamanzi nangaliphi na ixesha ngoqhagamshelwano olungenacingo kunye neefowuni eziphathwayo kunye neekhompyutha. Xa inqanaba lolwelo lingaphantsi kwexabiso elimiselweyo, inkqubo ikhumbuza abalimi ngokuzenzekelayo ukuba bankcenkceshe. Ngesi sisombululo sikrelekrele, amafama anciphise kakhulu inkunkuma yamanzi kwaye andisa imveliso yerayisi nge-10%.
