Zeziphi iintlobo zezivamvo zomgangatho wamanzi?
Nazi iintlobo ezisi-7 zezinzwa zenqanaba lolwelo kwireferensi yakho:

1. Inzwa yomgangatho wamanzi obonakalayo
Isivamvo soluvo sisimo esiqinileyo. Basebenzisa ii-LED ze-infrared kunye neefototransistors, kwaye xa i-sensor isemoyeni, zidibene ngokubonakalayo. Xa intloko ye-sensor intywiliselwa kulwelo, ukukhanya kwe-infrared kuya kubaleka, kubangele ukutshintshwa kwemveliso. Ezi zivamvo zinokubona ubukho okanye ukungabikho phantse naluphi na ulwelo. Azikhathali kukukhanya okungqongileyo, azichatshazelwa ligwebu xa zisemoyeni, kwaye azichatshazelwa ngamaqamza amancinci xa zikulwelo. Oku kubenza babe luncedo kwiimeko apho utshintsho lwelizwe kufuneka lurekhodwe ngokukhawuleza nangokuthembekileyo, kwaye kwiimeko apho banokusebenza ngokuthembekileyo ixesha elide ngaphandle kokugcinwa.
I-Advantages: umlinganiselo ongeyena uqhagamshelwano, ukuchaneka okuphezulu, kunye nokuphendula ngokukhawuleza.
Ukungalungi: Ungasebenzisi phantsi kwelanga elithe ngqo, umphunga wamanzi uya kuchaphazela ukuchaneka komlinganiselo.

2. Isivamvo senqanaba lolwelo lwamandla
Ukutshintsha kwenqanaba le-Capacitance sebenzisa i-electrode ye-2 conductive (ngokuqhelekileyo yenziwe ngetsimbi) kwisiphaluka, kwaye umgama phakathi kwabo ufutshane kakhulu. Xa i-electrode intywiliselwa kulwelo, igqibezela isiphaluka.
Izinto eziluncedo: zingasetyenziselwa ukumisela ukunyuka okanye ukuwa kolwelo olukwisikhongozeli. Ngokwenza i-electrode kunye nesitya sokuphakama okufanayo, i-capacitance phakathi kwe-electrodes inokulinganiswa. Akukho capacitance kuthetha ukuba akukho lulwelo. I-Capacitance epheleleyo imele i-container epheleleyo. Amaxabiso alinganisiweyo "angenanto" kunye "nokugcwele" kufuneka abhalwe, kwaye emva koko i-0% kunye ne-100% yeemitha ezilinganisiweyo zisetyenziselwa ukubonisa inqanaba lolwelo.
Ukungalungi: I-corrosion ye-electrode iya kutshintsha i-capacitance ye-electrode, kwaye kufuneka ihlambuluke okanye ihlaziywe.

3. Ukuguqula iqondo loluvo lwefolokhwe
Inqanaba lokulinganisa ifolokhwe yokulinganisa inqanaba lolwelo lokutshintsha isixhobo esiyilwe ngumgaqo wokulungisa ifolokhwe. Umgaqo wokusebenza wokutshintsha kukubangela ukungcangcazela kwayo nge-resonance ye-piezoelectric crystal.
Yonke into ine-resonant frequency. Ukuphindaphindwa kwezandi zento kunxulumene nobukhulu, ubunzima, imilo, amandla… wento. Umzekelo oqhelekileyo we-resonant frequency yento yile: ikomityi yeglasi efanayo ngokulandelelana Ukuzalisa amanzi obude obuhlukeneyo, unokwenza umculo wesixhobo ngokucofa.

Izinto eziluncedo: Ayichatshazelwa ngokwenene kukuhamba, amaqamza, iintlobo zolwelo, njalo njalo, kwaye akukho lungelelwaniso lufunekayo.
Ukungalungi: Ayinakusetyenziswa kwimidiya ye-viscous.

4. Inzwa yenqanaba lolwelo lwe-diaphragm
I-diaphragm okanye i-pneumatic level switch ixhomekeke kuxinzelelo lomoya ukutyhala i-diaphragm, edibanisa ne-micro switch ngaphakathi komzimba oyintloko wesixhobo. Njengoko inqanaba le-liquid linyuka, uxinzelelo lwangaphakathi kwi-tube yokufumanisa luya kunyuka kuze kube yilapho i-microswitch ivuliwe. Njengoko inqanaba le-liquid lihla, uxinzelelo lomoya luyehla, kwaye umtshintshi uvula.
Izinto eziluncedo: Akukho mfuneko yamandla etankini, ingasetyenziswa neentlobo ezininzi zolwelo, kwaye umtshini awuzukudibana nolwelo.
Iingxaki: Kuba isisixhobo esisebenza ngomatshini, siya kufuna ukulungiswa ekuhambeni kwexesha.

5.Inzwa yomgangatho wamanzi edadayo
Ukutshintsha okudadayo yinzwa yomgangatho wokuqala. Zizixhobo zoomatshini. Indawo edadayo idityaniswe nengalo. Njengoko i-float iphakama kwaye iwela kulwelo, ingalo iya kutyhalwa inyuke kwaye ihle. Ingalo inokudityaniswa kumatshini wombane okanye umatshini wokumisela ukuvala/ukuvala, okanye inokudityaniswa kwigeyiji yenqanaba etshintshayo ukusuka ngokupheleleyo ukuya engenanto xa inqanaba lolwelo liwa.

Ukusetyenziswa kokutshintsha okudadayo kwiimpompo yindlela eyongayo nesebenzayo yokulinganisa inqanaba lamanzi kumngxuma wokupompa wegumbi elingaphantsi.
Izinto eziluncedo: Iswitshi edadayo inokulinganisa naluphi na uhlobo lolwelo kwaye inokuyilelwa ukusebenza ngaphandle konikezelo lwamandla.
Ukungalungi: Zinkulu kunezinye iintlobo zokutshintsha, kwaye ngenxa yokuba zisebenza ngoomatshini, kufuneka zisetyenziswe rhoqo kunezinye iiswitshi zenqanaba.

6. Inzwa yenqanaba lolwelo lwe-ultrasonic
I-ultrasonic level gauge yi-digital level gauge elawulwa yi-microprocessor. Kwimilinganiselo, i-pulse ye-ultrasonic ikhutshwe yinzwa (i-transducer). I-wave yesandi ibonakaliswa ngumphezulu wolwelo kwaye ifunyenwe yinzwa efanayo. Iguqulwa ibe ngumqondiso wombane ngekristale ye-piezoelectric. Ixesha phakathi kokudluliselwa kunye nokwamkelwa kwezandi zomsindo lisetyenziselwa ukubala umlinganiselo womgama ukuya kumphezulu wolwelo.
Umgaqo osebenzayo we-ultrasonic level sensor level kukuba i-ultrasonic transducer (probe) ithumela i-high-frequency pulse sound wave xa idibana nomphezulu wezinga elilinganisiweyo (izinto eziphathekayo), ibonakaliswe, kwaye i-echo ebonakalisiweyo ifunyenwe i-transducer kwaye iguqulelwe kwisignali yombane. Ixesha lokusasazwa kwezandi zesandi. Ilingana nomgama ukusuka kwizandi zesandi ukuya kumphezulu wento. Ubudlelwane phakathi komgama wokuhanjiswa kwamaza omsindo S kunye nesantya sesandi C kunye nexesha lokuhambisa isandi T inokubonakaliswa ngefomula: S = C × T / 2.

Izinto eziluncedo: umlinganiselo ongaqhagamshelwanga, umlinganiselo ophakathi uphantse ube mda, kwaye unokusetyenziswa ngokubanzi ukulinganisa ubude bolwelo olwahlukeneyo kunye nezixhobo eziqinileyo.
Ukungalungi: Ukuchaneka komlinganiselo kuchaphazeleka kakhulu ngubushushu kunye nothuli lwendalo yangoku.

7. Igeyiji yenqanaba lerada
Inqanaba lolwelo lweradar sisixhobo sokulinganisa inqanaba lolwelo olusekelwe kumgaqo wokuhamba kwexesha. I-radar wave ibaleka ngesantya sokukhanya, kwaye ixesha lokubaleka linokuguqulwa libe ngumqondiso wenqanaba ngamacandelo e-elektroniki. I-probe ithumela i-high-frequency pulses ehamba ngesantya sokukhanya esikhaleni, kwaye xa ii-pulses zidibana nomphezulu wezinto eziphathekayo, zibonakaliswa kwaye zamkelwe ngummkeli kwimitha, kwaye umqondiso womgama uguqulwa ube kwinqanaba. uphawu.
Izinto eziluncedo: uluhlu olubanzi lwesicelo, aluchatshazelwa bubushushu, uthuli, umphunga, njl.
Ukungalungi: Kulula ukuvelisa i-echo yokuphazamiseka, echaphazela ukuchaneka komlinganiselo.
