Chiyero chekuyerera kwemvura che ultrasonic chakavhurika chekushandisa maflumu eParshall

Chiyero chekuyerera kwemvura cheOpen channel ultrasonic chinosanganisira kushandisa chiyero chekuyerera kwemvura cheultrasonic pamwe chete neParshall flume kuyera kuyerera kwemvura mugwara rakavhurika. Heano zvinhu zvakakosha:

1. Mashandiro azvinoita:
   • Frumu yeParshall: Frumu yeParshall chimiro chakasimba chehydraulic chinokurumidza kuyerera kwemugero usina kukosha, wakavhurika. Inokwenya madziro ese ari maviri akaenzana uye ine kudonha pasi pahuro yeflumu. Izvi zvinobvumira mwero wekuyerera kwemvura muchikamu chepamusoro cheflumu kuti utariswe nekuyera kwemazinga rimwe chete panzvimbo yakatarwa.
   • Chiyero chekuyerera kwemvura chinogadzirwa ne ultrasonic: Sensor yakaiswa pamusoro pemvura inoyerera muParshall flume inotumira ruzha runoonekwa nepamusoro pemvura. Nguva inopfuura pakati pekutumira pulse nekugamuchira echo inosarudza huwandu hwemvura muflume. Kuyerwa kwehuwandu uku kunozoshandurwa kuita chiyero chekuyerera kwemvura kuburikidza nekushandisa equation yakarongwa kare yakanangana nerudzi nehukuru hweflume iri kushandiswa.
2. Zvakanakira:
   • Kururama: Inogona kupa kururama kwakakwana pakuyera kuyerera, kazhinji mukati me ± 8-10% zvichienderana nezvinhu zvakasiyana-siyana zvakaita sekururama kweflume, kururama kwe flow meter, kukanganisa kwekuisa, uye kukanganisa kwe calibration.
   • Kuisa pasina kubatana: Sensor ye ultrasonic haibate mvura, zvinoreva kuti haina kukanganiswa nezvinhu zvakaita semafuta, zvinhu zvakanyungudutswa, silt, uye makemikari anoparadza ari murwizi rwemvura. Inodawo kugadziriswa kushoma.
   • Mashandisirwo akasiyana-siyana: Mafuru eParshall anoshandiswa zvakanyanya mumabasa akasiyana-siyana akadai semigero yekudiridza, mvura yepamusoro, maindasitiri, uye nzvimbo dzekuchenesa mvura yakasviba. Kusanganiswa ne ultrasonic flow meter kunoita kuti ive mhinduro inoshanda pakuyera kuyerera kwemvura mumigero yakavhurika.
3. Zvakashata nematambudziko:
   • Zvinhu Zvakatipoteredza: Ma ultrasound flow meter anogona kukanganiswa nemhepo, utsi, uye tembiricha yemhepo. Kuchinja kwetembiricha yemhepo kunogona kukanganisa kumhanya kweruzha, saka flow meter inofanira kutsiva shanduko idzi. Chiedza chezuva chinogonawo kukanganisa mashandiro e sensor nekudziisa sensor nemaoko.
   • Kukanganiswa kwemvura inoyerera: Kutenderera kwemvura, furo, uye marara ari kuyerera mumvura zvinogona kupa huwandu hwemvura inoyerera yakawanda sezvo mita inogona kuona izvi isati yaona huwandu hwemvura inoyerera.
   • Zvinodiwa pakuisa flume: Maflume eParshall anofanira kunge akaenzana kubva kumberi kuenda kumashure uye kubva kudivi kuenda kudivi kuti apime nemazvo. Kunyangwe paine kugadziriswa kwakagadzirwa kune mamwe maflume, kuve nechokwadi chekuiswa nekurongeka kwakakodzera kwakakosha pakuyera kuyerera kwemafungu nemazvo.
