Ntlha ea pele, ultrasonic level meter
Ka kakaretso re bitsa leqhubu la molumo ka maqhubu a fetang 20kHz ultrasonic wave, wave wave ke mofuta oa leqhubu la mochini, ke hore, ho sisinyeha ha mochini ka har'a mokhoa oa ho hasana, o khetholloa ka maqhubu a phahameng, bolelele bo bokhutšoane, bo nyane. "diffraction phenomenon" le "directivity" e ntle, e ka fetoha phatlalatso ea lehlaseli le tataiso.
Ultrasonic attenuation ka metsi le lintho tse tiileng li nyane haholo, ka hona, matla a ho kenella a matla, haholo-holo maboneng a khanyang a opaque, ultrasonic e ka kenella ka bolelele ba limithara tse mashome, ho kopana le litšila kapa li-interfaces li tla ba le pontšo e kholo, tekanyo ea ultrasonic level ke tšebeliso ea eona. tšobotsi ena.
Ho thekenoloji ea ho lemoha ha ultrasonic, ho sa tsotellehe hore na ke sesebelisoa sa mofuta ofe sa ultrasonic, hoa hlokahala ho fetola matla a motlakase hore e be ultrasonic emission, ebe o khutlisetsoa ka lipontšo tsa motlakase, sesebelisoa sa ho phetha mosebetsi ona se bitsoa ultrasonic transducer, e tsejoang hape e le probe.
Ha e sebetsa, transducer ea ultrasonic e behoa ka holim'a ntho e lekantsoeng 'me e ntša leqhubu la ultrasonic tlase.Leqhubu la ultrasonic le feta moeeng oa moea, le bontšoa morao ha le kopana le bokaholimo ba ntho e lekantsoeng, 'me le amoheloa ke transducer ebe le fetoloa letšoao la motlakase.Ka mor'a ho lemoha letšoao lena, karolo ea ho lemoha ha elektroniki e e fetola letšoao la boemo bakeng sa pontšo le tlhahiso.
Ea bobeli, radar level meter
Mokhoa oa ho sebetsa oa meter level ea radar o tšoana le oa ultrasonic level meter meter, le meter ea boemo ba radar e boetse e sebelisa mokhoa oa ho fetisa - ho bonahatsa - ho amohela mokhoa oa ho sebetsa.Phapang ke hore tekanyo ea radar ultrasonic level meter haholo-holo e itšetlehile ka transducer ea ultrasonic, ha meter ea boemo ba radar e itšetlehile ka hlooho ea maqhubu a phahameng le antenna.
Limithara tsa boemo ba Ultrasonic li sebelisa maqhubu a mochini, ha limithara tsa boemo ba radar li sebelisa maqhubu a phahameng haholo (a mangata G ho isa ho mashome a G Hertz) maqhubu a motlakase.Maqhubu a motlakase a tsamaea ka lebelo la khanya, 'me nako ea ho tsamaea e ka fetoloa letšoao la boemo ka likarolo tsa elektroniki.
Metara e 'ngoe e tloaelehileng ea boemo ba radar ke mitha ea boemo ba radar e tataisoang.
Guided wave radar level meter ke mitha ea boemo ba radar e ipapisitseng le molao-motheo oa time domain reflectometry (TDR).Maqhubu a motlakase a methareng ea boemo ba radar a ata ka thapo ea tšepe kapa probe ka lebelo la khanya.Ha e kopana le bokaholimo ba sekala se lekantsoeng, karolo ea sekhahla sa meter ea boemo ba radar e bonts'oa ho etsa echo ebe e khutlela sesebelisoa sa ho qala pulse ka tsela e ts'oanang.Sebaka se pakeng tsa transmitter le sebaka se mahareng se lekantsoeng se lekana le nako ea ho hasana ha sekhahla seo bophahamo ba seemo sa mokelikeli bo baloang.
