Mumabasa emaindasitiri—kubva kumakambani anochenesesa mafuta kusvika kunzvimbo dzezviyo dzinochengetedza masilo egorosi, uye zvirimwa zvemvura yakasviba zvichitarisa matangi etsvina—kuyerwa kwakarurama kwemazinga kwakakosha. Kunoita kuti pave nekuchengetwa kwakachengeteka, kunogadzirisa manejimendi yezvinhu, kudzivirira kuwanda kwemafuta kana kuoma kwemvura, uye kunotsigira mashandiro ekugadzira asina musono. Zvisinei, zvishandiso zvechinyakare zvekuyera mazinga zvakaita semasensa eultrasonic, maswichi efloat, kana matransmitter epressure zvinowanzo tambura munzvimbo dzakaoma kana dzakaoma: masaini eultrasonic anovharwa neguruva kana utsi, mafloat anonamira mumvura ine viscous, uye matransmitter epressure anokundikana mumatangi ane tembiricha dzakasiyana kana media inoparadza. Pinda mutransmitter yeradar level isina kubatana—mhinduro inoshandura mutambo inopa kururama kusingaenzaniswi kwekuyera tangi nesilo level, kunyangwe mumamiriro ezvinhu akaoma zvikuru.
Pakati payo, chinotumira radar level chinoshanda pasi pemutemo wekuti time-of-flight (ToF). Chinoburitsa ma radar pulses ane frequency yakakwira (kazhinji 24GHz kana 80GHz) kubva pa antenna yakaiswa pamusoro petangi kana silo. Ma pulses aya anofamba achienda pasi, obva abuda pamusoro pemvura, yakasimba, kana slurry iri mukati, obva adzokera kune chinotumira. Mudziyo uyu unoverenga nguva inotorwa kuti ma pulses afambe pamusoro odzoka, wobva washandisa data iri (pamwe nekumhanya kwemafungu e radar) kuverenga daro chairo kubva kuchinhu chacho—kwachinobva nhanho yazvino. Kusiyana nezvishandiso zvinoenderana nekubatana, hachimbobati chinhu chakayerwa, zvichibvisa njodzi yekusakara, kusvibiswa, kana kutadza kwemuchina.
Chinosiyanisa tekinoroji iyi nekunyatsorongeka kwayo, chinhu chakakosha pakushandiswa kwematangi nemasilo uko kunyangwe zvikanganiso zvidiki zvekuyera zvinogona kukonzera mhedzisiro inodhura. Mazhinji ma transmitter asingabatanidzwe neradar level ane kururama kwe ±1mm kusvika ±5mm, zvichienderana nemuenzaniso uye huwandu hwekuyera (hunogona kubva pa 0.3 metres kusvika pa 80 metres). Kunyatsorongeka uku kunoshanda kunyangwe mumamiriro ezvinhu anochinja: semuenzaniso, mumatangi emafuta ane nzvimbo dzakatenderedza kana masilo ane zvinhu zvinoyerera zvakaita se simende kana mapurasitiki. Zvinhu zvepamusoro zvakaita se echo filtering uye signal processing algorithms zvinowedzera kurongeka nekuregeredza manyepo kubva kumadziro ematangi, zvivakwa zvemukati (senge agitators kana baffles), kana makore eguruva - matambudziko akajairika anotambudza mamwe maturusi ekuyera.
Imwe mukana wezvishandiso zveradar zvisingabatanidzi vanhu ndeyekushanda kwadzo munzvimbo dzakasiyana-siyana dzematangi nenzvimbo dzemasilo. Zvinobata zvakasiyana-siyana zvemagetsi: zvinwiwa (kusanganisira mahydrocarbon, makemikari, nemvura), zvinhu zvakasimba (zviyo, hupfu, uye mapellets), uye kunyange matope akaoma kuyera (senge matope emvura yakasviba kana matope emumigodhi). Dhizaini yazvo yakasimba inoramba iri mumamiriro ezvinhu akaipisisa: tembiricha yepamusoro (kusvika 200°C kana kupfuura nemamodeli akasarudzika), kumanikidzwa kwakanyanya (kusvika 100 bar), uye mhepo inoparadza—zvichiita kuti zvive zvakanaka kumaindasitiri akadai semafuta, chikafu nezvinwiwa, uye kuchera. Mamodheru mazhinji anouyawo neIP67 kana IP68 dziviriro, zvichivimbisa kuramba guruva, mvura, uye hunyoro, izvo zvakakosha kumasilo ekunze kana nzvimbo dzekugadzirisa mvura.
Kune vanoshanda mumaindasitiri, mabhenefiti acho anopfuura kurongeka uye kugara kwenguva refu kusvika pakushanda zvakanaka. Ma "radar transmitters" asingabatanidzwi anoda kugadziriswa kushoma: pasina zvikamu zvinofamba kana kusangana ne "medium", hapana chikonzero chekuchenesa nguva dzose, kugadzirisa, kana kutsiva zvikamu - kusiyana nema "float switches" anoda kutarisirwa kakawanda kana kuti ma "pressure transmitters" anowanzo vharika. Anobatanidzwawo zvakanaka nema "control systems" aripo kuburikidza nema "standard protocols" akadai seModbus, HART, kana 4-20mA analog output. Izvi zvinoreva kuti data re "level" rinogona kutumirwa munguva chaiyo kuma "SCADA systems", "inventory management software", kana "cloud-based platforms", zvichibvumira vashandi kutarisa mazinga vari kure, kuisa otomatiki zviziviso zve "low/high levels", uye kuita sarudzo dzinotungamirirwa nedata nezvekuzadzazve kana kubvisa matangi/silos.
Funga nezve lifti hombe yezviyo ine masilo akawanda anochengeta gorosi nechibage. Chinotumira radar level chisingabatanidzwe chakaiswa pa silo yega yega chinopa data rakarurama, renguva chaiyo, zvichigonesa nzvimbo iyi kutevera zvinhu zviri muchitoro pasina kuongororwa nemaoko (izvo zvinotora nguva uye zvine njodzi). Kana silo yasvika pahuwandu hwezvinhu, sisitimu iyi inotanga yambiro yekumisa kupinda kwezviyo, zvichidzivirira kuwanda kwazvo. Munzvimbo yekuchenesa mafuta, zvinotumira radar pamatangi emafuta asina kucheneswa zvinovimbisa kuyerwa kwakarurama kwehuwandu hwakachengetwa, zvichitsigira kutevedzera zvinodiwa nemutemo uye kugadzirisa hurongwa hwekutumirwa kwematangi.
Mukupedzisa, chinotumira radar level chisiri chekubata chagadzirisa patsva kuyerwa kwetangi ne silo level. Dhizaini yaro isina kubata inobvisa zvikanganiso zvezvishandiso zvechinyakare, kunyatsorongeka kwayo kunoderedza njodzi dzekushanda, uye kushanduka kwayo kunoenderana nezvinodiwa zvakasiyana-siyana zvemaindasitiri. Kune mabhizinesi ari kutsvaga kusimudzira kuchengetedzeka, kugadzirisa manejimendi yezvinhu, uye kuvandudza kushanda zvakanaka, tekinoroji iyi haisi yekungoyera chete—chinhu chakakosha chinokurudzira kuvimbika nekubudirira mumabasa emazuva ano emaindasitiri.
