Njengendawo ebalulekileyo yokutyala izityalo, ukunkcenkceshela kunye nolawulo lwamanzi emasimini erayisi kudlala indima ebalulekileyo kumgangatho kunye nesivuno semveliso yerayisi. Ngophuhliso lwezolimo zanamhlanje, ukusetyenziswa kakuhle kunye nolawulo lwezixhobo zamanzi kube ngumsebenzi obalulekileyo. Imitha yokulinganisa ubungakanani bemitha iye yaba lukhetho olufanelekileyo lokujonga ubungakanani bamanzi emasimini erayisi ngenxa yokuchaneka kwayo okuphezulu, ukuzinza kunye nokuqina kwayo. Eli nqaku liza kuxoxa ngomgaqo wokusebenza, iingenelo zokusetyenziswa, iimeko ezisebenzayo kunye namathuba ophuhliso lwemitha yokulinganisa ubungakanani bemitha emasimini erayisi.
1. Umgaqo wokusebenza wemitha yenqanaba le-capacitive
Umgaqo wokusebenza wemitha yenqanaba le-capacitive usekelwe kutshintsho lwe-capacitance. Xa inqanaba lolwelo lwe-liquid medium litshintsha, i-dielectric constant ehambelanayo yolwelo ichaphazela i-capacitance ye-capacitor, ngaloo ndlela kufezekiswa ukulinganiswa kwenqanaba lolwelo. Amanyathelo athile ngala alandelayo:
Ulwakhiwo lwe-capacitor: Imitha yenqanaba le-capacitive idla ngokuba nee-electrodes ezimbini, enye yazo yi-probe kwaye enye idla ngokuba yi-ground wire okanye i-container ngokwayo.
Utshintsho olungaguqukiyo lweDielectric: Utshintsho lwenqanaba lolwelo luya kubangela utshintsho lwendlela ephakathi kwee-electrodes. Xa inqanaba lolwelo linyuka okanye lihla, i-dielectric constant ejikeleze i-electrode (njenge-dielectric constant yomoya yi-1, kwaye i-dielectric constant yamanzi imalunga nama-80) iyatshintsha.
Ukulinganiswa komthamo: Imitha yenqanaba isoloko ijonga utshintsho lwe-capacitance kwisekethe, ize iyiguqule ibe yimveliso yamanani yenqanaba lolwelo.
Isiphumo sesignali: Imitha yeleveli ngokubanzi idlulisela ixabiso leleveli elilinganisiweyo kwinkqubo yokulawula okanye kwisixhobo sokubonisa ngesignali ye-analog (efana ne-4-20mA) okanye isignali yedijithali (efana ne-RS485).
2. Iimpawu zemitha yenqanaba lomthamo kwiintsimi zerayisi
Uyilo kunye nokusetyenziswa kwemitha yokulinganisa ubungakanani bombane kwiintsimi ze-paddy kuthathela ingqalelo ubume bendawo yentsimi ye-paddy. Iimpawu zayo zibonakala kakhulu kwezi zinto zilandelayo:
Amandla aqinileyo okulwa nokuphazamiseka: Indawo ekwintsimi yerayisi iyinkimbinkimbi, kwaye imitha yenqanaba lomthamo idla ngokusebenzisa iisekethe zokulwa nokuphazamiseka xa iyila ukuqinisekisa uzinzo oluphezulu phantsi komswakama kunye notshintsho lwemozulu.
Ukulinganisa ngokuchanekileyo: Imitha yenqanaba le-capacitive ingabonelela ngokuchanekileyo kokulinganisa inqanaba lamanzi le-millimeter, okufanelekileyo kulawulo oluhle lokunkcenkceshela kunye nemithombo yamanzi.
Izinto ezimelana nokugqwala: Emasimini erayisi, imitha yokulinganisa kufuneka imelane nokugqwala okuvela emanzini, emhlabeni nakwezinye iikhemikhali, ngoko ke iprobe idla ngokwenziwa ngezinto ezimelana nokugqwala (ezifana nentsimbi engagqwaliyo, iplastiki, njl.njl.).
Kulula ukuyifaka nokuyilungisa: Imitha yokulinganisa ubungakanani bombane ilula ukuyila, ayithathi ndawo ingako yokuyifaka, kwaye kulula ukuyilungisa, nto leyo eyenza ifaneleke ukusetyenziswa kwiindawo zasemaphandleni.
Umsebenzi wokubeka esweni okude: Iimitha ezininzi zokulinganisa amandla emasimini erayisi zixhotyiswe ngeemodyuli zonxibelelwano ezingenazingcingo, ezinokufezekiswa kokubeka esweni okude kunye nolawulo lwedatha, kwaye ziphucule inqanaba lobukrelekrele lolawulo lokunkcenkceshela.
3. Iingenelo zokusetyenziswa kweemitha zenqanaba le-capacitive kumasimi erayisi
Ulawulo lwezixhobo zamanzi: Ngokujonga inqanaba lamanzi ngexesha langempela emasimini erayisi, abalimi banokujonga ngokuchanekileyo iimfuno zokunkcenkceshela, banciphise inkunkuma yamanzi, kwaye baphucule ukusebenza kakuhle kwamanzi.
Ukwandisa isivuno sezityalo: Ulawulo lwamanzi ngokwesayensi lunokukhuthaza ukukhula nophuhliso lwerayisi, luqinisekise ukubonelelwa kwamanzi okwaneleyo, kwaye luthintele ukuncipha kwemveliso okubangelwa kukunqongophala kwamanzi okanye ukuqokelelwa kwamanzi.
Ulimo olukrelekrele: Ngokudibanisa iteknoloji ye-sensor kunye ne-Intanethi yezinto, iimitha zenqanaba lomthamo zinokufakwa kwinkqubo yolawulo lwezolimo iyonke ukwenza isisombululo sokunkcenkceshela esikrelekrele kunye nokufezekisa ulimo oluchanekileyo.
Ukwenziwa kwezigqibo ezixhaswa yidatha: Ngokubeka esweni ixesha elide kunye nohlalutyo lwedatha yomgangatho wamanzi, abalimi kunye nabaphathi bezolimo banokwenza izigqibo zesayensi ngakumbi, baphucule iindlela zokulima kunye nexesha, kwaye baphucule umgangatho wolawulo lwezolimo ngokubanzi.
4. Amatyala okwenyani
Ityala 1: Ulawulo lwamanzi kwintsimi yerayisi eVietnam
Kwintsimi yerayisi eVietnam, abalimi ngokwesiko baxhomekeke ekuhlolweni kwamanqanaba amanzi ngesandla xa benkcenkceshela.
