Ultrasonic Flow Meters

Isipiliyoni Sokukhiqiza Seminyaka engu-20+

I-TRANSDUCER SPACING ye-transit time clamp ku-flowmeter ye-ultrasound

Isikhathi sokuhamba nge-ultrasonic clamp-on transducersziboshelwe ngaphandle kwepayipi elivaliwe ebangeni elithile ukusuka kwelinye.Ama-transducer angafakwa ku-V-mode lapho umsindo unqamula ipayipi izikhathi ezimbili, W-mode lapho umsindo unqamula ipayipi izikhathi ezine, noma ku-Z-mode lapho ama-transducer afakwe ezinhlangothini eziphambene zepayipi kanye neziphambano zomsindo. ipayipi kanye.Ukuze uthole imininingwane eyengeziwe, bheka izithombe ezitholakala ngaphansi kweThebula 2.2.Ukucushwa okufanelekile kokukhweza kusekelwe kumapayipi nezici zoketshezi.Ukukhethwa kwendlela efanele yokukhweza i-transducer akubikezeleki ngokuphelele futhi izikhathi eziningi kuyinqubo ephindaphindayo.Ithebula 2.2 liqukethe ukucupha okunconyiwe kwezinhlelo zokusebenza ezivamile.Lokhu kulungiselelwa okunconyiwe kungase kudingeke ukuthi kuguqulelwe izinhlelo zokusebenza ezithile uma izinto ezifana nokufaka umoya, okuqinile okumisiwe noma izimo ezimbi zamapayipi zikhona.Imodi ye-W inikeza ubude bendlela yomsindo ende phakathi kwama-transducer - kodwa amandla esignali abuthakathaka.I-Z-mode inikeza amandla esignali aqine kakhulu - kodwa inobude bendlela yomsindo emfushane kakhulu.Emapayipini amancane kunamamilimitha angu-75, kuyafiseleka ukuba nobude bendlela yomsindo ende, ukuze isikhathi sokuhlukanisa singakalwa ngokunembe kakhudlwana.
