Isiri-yekubata nhanho kuyerwa ndeimwe yeakakosha tekinoroji muindasitiri otomatiki. Iyo nzira inogonesa kutarisa kwemvura kana yakasimba mazinga mutangi, mudziyo kana yakavhurika chiteshi pasina kupindirana kwemuviri nepakati. Pakati peanonyanya kushandiswa asiri ekubata nzira ndeye ultrasonic uye radar level metres. Kana mushandisi achida kushandisa isiri-yekubata chiyero padanho rekutonga, kunzwisisa kwekushanda kwea ultrasonic uye radar mhando yegeji yemhando inobatsira kuita sarudzo yakakodzera yeimwe mamiriro.
Nheyo yekushanda
Ultrasonic level gaugesshanda nekuburitsa kuputika kwepamusoro-frequency kuputika kwemafungu eruzha kuti uwane huwandu kubva kune sensor kusvika pamusoro peiyo mvura / yakasimba svikiro. Aya masaisai anofamba nemumhepo, anoratidza kubva pane zvinhu, uye anodzokera kune sensor. Chinhambwe chinogona kutariswa nenguva yakashandiswa parwendo rwemasaisai. Naizvozvo chiridzwa chinoiswa chinhambwe chiri pamusoro pepakati pevhu, pasina chero chikamu chinofanira kubatwa zvakananga kana kunyudzwa mukati mepakati.
Radar level gejiinoshandisa electromagnetic waves (microwaves) pachinzvimbo cheruzha kuona huwandu hwepakati hwemvura kana yakasimba. Saizvozvo microwave masaini anoburitswa akananga epakati pepamusoro obva aratidzwa uye anogamuchirwa achidzokera kuchiridzwa. Panguva yekuita hapana zvakare kubata kwemuviri pakati pechiridzwa chemuviri nepakati. Kuburikidza nenguva yekurekodha yekubhururuka kwemasaisai masaini, chinhambwe kubva kune chiridzwa kuenda kune chinhu chepamusoro chinogona kuverengerwa.
Zviyero zvemazinga emarudzi maviri aya anogovera mafomula akafanana:
D = (C*T)/2
L = H - D
Kupi,
D: Chinhambwe kubva pakati pepamusoro kusvika kune chiridzwa
C: Velocity of sound (ye ultrasonic) velocity of light (ye radar)
T: Nguva yekufamba kubva pakuburitsa kusvika pakugamuchira
L: Chiyero chepakati chinofanira kuyerwa
H: Hurefu kubva mumudziyo pasi kusvika kune chiridzwa
Siyana kubva kune zvakajairwa-zvakavakirwa zviridzwa, kubviswa kwekubata kwepanyama nechinhu, ultrasonic uye radar tekinoroji inokunda padanho rekutonga kwezvinhu zvinoparadza, viscous, kana zvine ngozi zvinogona kukuvadza kana kuvhara zvinhu zvakanyorova sezvinoyangarara, probes, kana mitsara yekumanikidza. Kuiswa kunorerutswa sezvo zvishandiso zvakaiswa kunze uye kuchengetedza uye kudzika nguva zvinodikanwa zvinowanzochengetwa zvishoma nekuda kweiyo isiri-invasive dhizaini. Maindasitiri senge kugadzirwa kwemakemikari, kurapwa kwemvura, uye kugadzira chikafu kunogona kubatsirwa zvakanyanya kubva kune ultrasonic uye radar isiri-yekubata level sensors nekuda kwekuita kwavo kwakasiyana-siyana uye kuvimbika pakati pemaitiro ekudzora emvura, fluid, slurry, uye yakasimba kune akasiyana tangi geometries.
Kuenzanisa pakati pe ultrasonic uye radar
Ultrasonic level mita iri nyore kuisirwa uye inoda kushoma setup. Kuenzaniswa ne radar level mita, iyo ultrasonic imwe inowanzo dhura zvishoma uye saka inofarirwa mumashandisirwo ane bhajeti zvinonetsa. Nekudaro, kuita kwezviridzwa zveultrasonic zviri pasi pezvakatipoteredza mhedzisiro yeguruva, furo, mhepo kusagadzikana uye yakanyanya tembiricha uye hunyoro hunogona kutora kana kukanganisa mafungu eruzha uye kukonzera kurasikirwa kwemafungu.
Radar level gauge, kune rumwe rutivi, inozivikanwa nekunyanya kurongeka, kureba uye kuvimbika kwakasimbiswa munzvimbo ine hutsinye hwekushanda. Izvo zvishoma zvinokonzeresa kune zvinhu zviri pamusoro peiyo dambudziko ultrasonic tekinoroji. Zvakadaro zvinoreva kuti zvigadzirwa zveradar zvinowanzodhura zvakanyanya. Dielectric constant chimwe chinhu chakakosha pakuyera radar. Yakaderera dielectric zvinhu zvinogona kunetesa kuratidzwa kwechiratidzo cheecho chinotungamira kune isina kugadzikana kana kurasika kuyerwa.
Muchidimbu, kana mushandisi afunga kushandisa isiri-yekusangana chiyero kuyerwa, ultrasonic sensor ingave yakakodzera kune ine mwero kushanda mamiriro uye bhajeti-inoziva purojekiti nepo radar inokodzera kune yakanyanya kunetsa nharaunda uye kutsvaga yakakwira mwero kuyerwa. Chero zvazvingaitika, zvakakosha kuona kuti hunhu hwepakati uye nharaunda, pamwe nechimiro chehurongwa hwekuita, zvinogoneka kuita iyo inodiwa yekuyera nzira yekuyera.

- ✦ Nzvimbo yekuisa inofanirwa kunge iri kure sezvinobvira kubva kune ruzha sosi
- ✦ Rubber gasket inogona kushandiswa kukwira pasi pe vibration nharaunda
- ✦ Chinhambwe kubva pasensor kuenda padanho repamusoro rinofungidzirwa rinofanira kunge rakakura kupfuura kuyerwa kwemapofu
- ✦ Sensor chinzvimbo inofanirwa kuchengetedza imwe chinhambwe nemadziro emudziyo zvinoenderana neemitting angle
- ✦ Nzvimbo yekuyera inofanira kunge isina zvipingamupinyi zvinogona kukonzera kukanganiswa kwechiratidzo senge nhanho manera kana crossbeam.
- ✦ Kuyero yakasimba yepakati, yekukwirisa nzvimbo inofanirwa kudzivirira zvinhu zvekuvhura nzvimbo
- ✦ Zvakanakisa kudzivirira kuchinjika kukuru kwekushisa panzvimbo yekuisa chiridzwa
- ✦ Sensor probe ichave perpendicular kune yepakati pepamusoro kuti ichengetedze kuita kwakanyanya
Shanghai Wangyuaninyanzvi yekugadzira chiridzwa pamusoro pemakore makumi maviri ichipa ultrasonic uye radar contactless level sensors pamwe nemamwe marudzi emayero ekuyeresa zviridzwa. Ndapota inzwa wakasununguka kutibvunza nezvako zvauchabvunza pane zvisiri-yekubata level yekuyera zvigadzirwa.
