Transit-nguva kushanda musimboti
Nheyo yekuyera:
Iyo Transit-nguva Correlation Principle inoshandisa chokwadi chekuti nguva-yekubhururuka kweiyo ultrasonic siginecha inokanganiswa nekuyerera velocity yepakati inotakura.Somushahwi ari kushanda achiyambuka rwizi runoyerera, chiratidzo cheultrasonic chinofamba zvishoma nezvishoma chichikwira nepamusoro perwizi.
YeduTF1100 ultrasonic kuyerera mitashanda zvinoenderana neiyi musimboti wenguva yekufambisa:
Vf = Kdt/TL
Kupi:
VcFlow velocity
K: Nguva dzose
dt: Musiyano munguva yekubhururuka
TL: Ave kutsamwa Transit Nguva
Kana iyo yekuyerera mita ichishanda, maviri matransducer anotapurirana uye anogashira ultrasonic masiginecha anokwidziridzwa neakawanda danda iyo inofamba yekutanga ichidzika nekudzika.Nekuti ruzha rwepamusoro runofamba nekukurumidza kudzika kupfuura kumusoro, pachava nemusiyano wenguva yekubhururuka (dt).Kana kuyerera kuchiri, musiyano wenguva (dt) i zero.Naizvozvo, chero tichiziva nguva yekubhururuka zvese kuzasi nekukwidza, tinokwanisa kugadzirisa musiyano wenguva, uyezve kuyerera velocity (Vf) kuburikidza neinotevera fomula.

Doppler inoshanda musimboti
TheDF6100series flowmeter inoshanda nekutumira ultrasonic sound kubva kune inotapurirana transducer, ruzha rwunozoratidzwa neanobatsira sonic maratidziro akamiswa mukati memvura uye akarekodhwa neanogamuchira transducer.Kana iyo sonic reflectors ichifamba mukati meiyo ruzha nzira yekufambisa, mafungu eruzha anozoratidzwa pane frequency yakachinjika (Doppler frequency) kubva kune inofambiswa frequency.Iko kushanduka kwema frequency kuchave kwakanangana nekumhanya kwechitubu chinofamba kana bubble.Kuchinja uku kwefrequency kunodudzirwa nechiridzwa uye kuchinjirwa kune akasiyana-siyana anotsanangurwa mayuniti ekuyeresa.
Panofanira kunge paine zvimwe zvimedu zvakakura zvakakwana kuti zvikonzere kureba kutarisisa - zvimedu zvakakura kupfuura 100 micron.
Paunenge uchiisa ma transducers, nzvimbo yekuisa inofanira kuva yakakwana yakatwasuka pombi kureba kumusoro kwerwizi.Kazhinji, kukwidza kunoda 10D uye kudzika kunoda 5D yakatwasuka pombi kureba, uko D iri dhayamita yepombi.
Area velocity working principle
DOF6000yakatevedzana yakavhurika chiteshi kuyerera mita inoshandisa Inoenderera Mode Doppler kuona kumhanya kwemvura, iyo ultrasonic siginecha inopfuudzwa mukuyerera kwemvura uye echoes (mafungidziro) anodzoserwa kubva kuzvikamu zvakamiswa mukuyerera kwemvura anogamuchirwa uye kuongororwa kuti abvise Doppler shift (velocity).Kutumira kunoenderera mberi uye panguva imwe chete nekudzoka kwechiratidzo chekugamuchira.
Munguva yekuyera kutenderera Ultraflow QSD 6537 inoburitsa chiratidzo chinoenderera uye inoyera masaini anodzoka kubva kune anoparadzira chero kupi uye kwese kwese kwedanda.Izvi zvinogadziriswa kune imwe nhanho yevelocity inogona kuve yakabatana nechiteshi chekuyerera velocity panzvimbo dzakakodzera.
Iyo inogamuchira muchiridzwa inoona zviratidzo zvinoratidzwa uye izvo zvikwangwani zvinoongororwa uchishandisa madhijitari ekugadzirisa masaini.
Kuyera Kwakadzika Kwemvura - Ultrasonic
Pakuyera kuyerwa Ultraflow QSD 6537 inoshandisa Nguva-ye-Ndege (ToF) Kutarisa.Izvi zvinosanganisira kuendesa kuputika kweiyo ultrasonic chiratidzo kumusoro kumusoro kwemvura uye kuyera nguva inotorwa kuti echo kubva pamusoro kuti igamuchirwe nechiridzwa.Chinhambwe (kudzika kwemvura) chinoenzanirana nenguva yekufambisa uye kumhanya kweruzha mumvura (yakagadziriswa tembiricha nekuwanda).
Iyo yakanyanya ultrasonic kudzika kuyerwa kunogumira kune 5m.
Kuyera Kudzika Kwemvura - Kudzvinyirira
Nzvimbo dzine mvura ine marara akawanda kana mabhuru emhepo anogona kunge asina kukodzera kuyera kudzika kwe ultrasonic.Nzvimbo idzi dzakanyatsokodzera kushandisa kudzvanywa kuona kudzika kwemvura.
Kupimwa kwakavakirwa kudzika kuyerwa kunogona zvakare kushanda kune nzvimbo uko chiridzwa chisingawanikwe pauriri hwechiteshi chekuyerera kana chisingagoni kukwidzwa chakatwasuka.
Ultraflow QSD 6537 yakaiswa ne 2 bars absolute pressure sensor.Iyo sensor iri pazasi pechiso chechiridzwa uye inoshandisa tembiricha yakabhadharwa yedhijitari kudzvanywa inonzwa chinhu.
Iko kunoshandiswa masensa ekudzika kwemhepo kunoshandiswa kushanduka kwemhepo kunokonzeresa kukanganisa mukudzika kwakaratidzwa.Izvi zvinogadziriswa nekubvisa mhepo yemuchadenga kubva pakupimwa kwakadzika.A barometric pressure sensor inodiwa kuita izvi.Iyo yekumanikidza muripo wemodule yakavakirwa muCalculator DOF6000 iyo inozodzorera otomatiki kusiyanisa kwemhepo yemhepo kuve nechokwadi kuti kuyerwa kwakadzika kunowanikwa.Izvi zvinoita kuti Ultraflow QSD 6537 itaure kudzika kwemvura chaiko (kudzvanywa) panzvimbo yebarometric pressure pamwe nemusoro wemvura.
Tembiricha
A solid state tembiricha sensor inoshandiswa kuyera tembiricha yemvura.Iko kumhanya kwenzwi mumvura uye maitiro ayo anokonzerwa nekushisa.Chiridzwa chinoshandisa tembiricha yakayerwa kuti idzore otomatiki kune iyi musiyano.
Electrical Conductivity (EC)
Ultraflow QSD 6537 inoshongedzerwa nekukwanisa kuyera mafambisirwo emvura.A linear mana electrode configuration inoshandiswa kuita kuyerwa.Ikozvino diki inopfuudzwa mumvura uye voltage inogadzirwa neichi ikozvino inoyerwa.Chiridzwa chinoshandisa hunhu uhwu kuverenga mbishi usina kurongeka conductivity.
