Nzira yakavhurika yeLanry QSD6537chiyero cheflowmeter, inoenderana ne DOF6000 flow calculator, imhando yepamusoro yekuyerera kwekukurumidza kwenzvimbomudziyo wekutarisa wakagadzirwa pamwe chete neLanry Instruments neUnidata. Kusiyana nemigero yemagetsi yakavhurika inoshandiswa pamadziro kana maflume, mudziyo uyu unoshandisa nzira yekumhanya kwenzvimbo senzira yawo yekuyera, pamwe chete netekinoroji yeultrasonic Doppler kuti iite kuyerwa kwakarurama kwemvura mumigero yakavhurika, nzizi dzechisikigo uye mapaipi akazadzwa zvishoma. Unobvisa zvinodiwa zvekuisa zvivakwa zvekutanga zvekuyerera kwemvura uye unopa kushanda kwakasimba mumapurojekiti ekuongorora mvura yetsvina, mvura yekudiridza uye mvura yepamusoro.
Iyokuyerera kwekutangaFomura yekuverenga yemuchina uyu inotevera hydromechanics: Q = V × A, apo Q inomiririra mwero wekuyerera kwemvura, V inomiririra avhareji yekukurumidza kwemvura, uye A inoreva nzvimbo yakanyorova yemugero panguva chaiyo. Kuti uwane kukosha kwekuyerera kwekupedzisira, sensor inopedza mabasa maviri ekuyera panguva imwe chete: kutora kumhanya kwemvura uye kuona kudzika kwemvura, nepo karukureta yekuyerera inotsigira ichiverenga nzvimbo yekukurumidza yekuyambuka uye kuyerera kwemvura zvichibva pamatanho ejometri yemugero.
Kuyerwa kwekukurumidza kwemvura kunoenderana nepfungwa ye ultrasonic Doppler ine tekinoroji ye quadrature sampling. Iyo QSD6537 integrated sensor inotumira ma ultrasonic pulses anoramba achienderera mberi mumvura inoyererakuburikidza ne epoxy sealed housing. Zvidimbu zvidiki zve sediment zvakasungirirwa uye ma micro air bubbles anotakurwa mumvura zvinodzosera ma ultrasound signals kudzokera ku built-in receiving transducer. Kana mvura yayerera, reflective wave inogadzira frequency shift, inozivikanwa seDoppler shift. Internal high-speed DSP module inoongorora frequency deviation uye inoshandura signal kuita real-time flow velocity. Sensor inotsigira bidirectional velocity detection, izvo zvinoita kuti ive yakakodzera kumvura dzemvura nema drainage pipes ane reverse.mamiriro ekuyereraKumhanya kwayo kunoyerwa kunosvika 0.02 m/s kusvika 13.2 m/s, zvichigutsa kuyerera kwetsvina kusingamhanye uye kutarisisa kuyerera kwerwizi nekukurumidza.
Kuti uzive kudzika kwemvura, QSD6537 inoshandisa nzira mbiri dzekuyera kuti ivandudze kuchinjika kwenzvimbo. Nzira yekutanga ndeyekuyera kudzika kwesimba remvura, kuverenga kudzika kwemvura zvichienderana nekusiyana kwekumanikidzwa kunoitwa nekoramu yemvura. Mhinduro yechipiri inoshandisa nzira yekutarisa kudzika kwemvura kuti ione daro riri pakati pesensa nepamusoro pemvura. Vashandisi vanogona kusarudza kana kusanganisa nzira mbiri dzekuyera kudzika zvichienderana nemamiriro enzvimbo. Maitiro ekugadzirisa tembiricha akavakirwa mukati uye kugadzirisa kumanikidzwa zvinobudirira anoderedza zvikanganiso zvekuyera zvinokonzerwa nekuchinja kwetembiricha yemhepo uye shanduko yekumanikidzwa kwemhepo. Uyezve, sensor yekutsvedza yemukati inogadzirisa otomatiki zvikanganiso zvekutsauka kana sensor yakaiswa pakona yakatsamira.
Chinhu chitsva chakakurumbira cheQSD6537 system chiri mubasa rayo rekuenzanisa zvinhu zvakasiyana-siyana.DOF6000 karukureta yekuyererainotsigira nzvimbo dzinosvika makumi maviri dzinobatanidza mvura kuti dzitsanangure ma profiles ema channel asina kurongeka, kusanganisira nzira dze trapezoidal, mapaipi akatenderera azere hafu uye zvikamu zverwizi zvakakombama zvechisikigo. Mushure mekutumira data re coordinate remiganhu yema channel, karukureta inoverenga zvine simba nzvimbo yakanyorova panguva chaiyo inoenderana nekudzika kwemvura kwakayerwa. Dhizaini iyi inowedzera zvikuru mamiriro ekushandiswa, kunyanya kune nzira dzemvura dzechisikigo uye mapaipi ekare emvura ane zvikamu zvisingawanzo shandiswa uko ma flume akajairwa asingagone kuiswa.
Kupfuura kutarisisa kumhanya nekudzika, probe iyi inogona kuunganidza mafambiro emvura uye tembiricha yepakati, ichipa data remhando yemvura yekutarisira zvakatipoteredza. Imba ye epoxy yeIP68 yakavharwa zvizere inobvumira kushanda kwenguva refu pasi pemvura pasina kugadziriswa kwakanyanya.
Muchidimbu,Lanry QSD6537Iyo open channel flowmeter inobatanidza ultrasonic Doppler velocity measurement, dual-mode depth depth depth uye programmable cross-section mode yakavakirwa pamutemo we area-velocity. Isina miganho yekuisa weir ne flume, sisitimu iyi inopa mhinduro inochinjika uye yakavimbika yekuongorora hydrological, kutarisa mvura yakasviba yemumaguta, kudiridza kwekurima uye manejimendi yeguta responge, zvichiita kuti ive chishandiso chinofarirwa chekuyera flow yemumunda yakazaruka pasi rese.
