Ultrasonic flowmeter wani nau'i ne na ma'aunin ma'auni mai gudana, amfani da ultrasonic bugun jini a cikin magudanar ruwa ta hanyoyi guda biyu na bambancin saurin gudu, don nemo magudanar ruwa, sabon nau'in mita na kwararar ultrasonic ya sami nasarar haɓaka akan sha na fa'idodi da yawa. na ultrasonic flowmeters a gida da waje.
Na'urar motsi na ultrasonic ya dogara ne akan bayanin saurin gudu lokacin da igiyar ultrasonic ke yaduwa a cikin ruwa mai gudana, kamar saurin yaduwa na kwararar gaba da juzu'i na juzu'i saboda babban matsayi na saurin ruwa.Sabili da haka, ana iya gano ƙimar ruwa ta hanyar igiyoyin ultrasonic da aka karɓa, wanda aka canza zuwa cikin ƙimar ruwa.Ultrasonic flowmeter ya ƙunshi ultrasonic transducer, lantarki da'ira da kwarara nuni da kuma tara tsarin.
Matsayin zaɓin zaɓi na Ultrasonic flowmeter dole ne yayi la'akari da waɗannan abubuwan: cikakken bututu, tsayayyen kwarara, ƙima, zazzabi, matsa lamba, tsangwama da sauransu.
1, cikakken bututu: Zaɓi sashin bututu cike da ingancin kayan kayan ruwa mai inganci, mai sauƙin watsawa na ultrasonic, kamar sashin bututu na tsaye (ruwan ruwa sama) ko sashin bututun kwance.
2, Tsayayyen kwarara: Ya kamata a zaɓi nisan shigarwa sama sama sama da sau 10 madaidaiciyar bututu diamita, ƙasa mafi girma fiye da sau 5 madaidaiciya diamita bututu ba tare da wani gwiwar hannu ba, raguwar diamita da sauran sashin madaidaiciya madaidaiciya, wurin shigarwa yakamata ya kasance mai nisa. daga bawul, famfo, babban ƙarfin lantarki da mai sauya mita da sauran hanyoyin tsangwama.
3, kauce wa shigarwa na waje matsa-nau'in ultrasonic flowmeter a cikin bututun tsarin a mafi girma batu ko free kanti a tsaye bututu (ruwa kwarara ƙasa)
4, don buɗaɗɗen bututu ko ba cikakke ba, ya kamata a shigar da mita kwarara a cikin sashin bututun U-dimbin yawa.
5, zafin jiki da matsa lamba na wurin shigarwa ya kamata su kasance cikin kewayon da firikwensin zai iya aiki.
6, cikakken la'akari da matsayi na sikelin bangon ciki na bututu: kodayake zaɓin shigarwar bututu ba tare da sikeli ba, idan ba zai iya saduwa ba, ana iya ɗaukar sikelin azaman rufin don ƙarin daidaiton aunawa.
7, dole ne a shigar da na'urori masu auna firikwensin na waje na ultrasonic flowmeter a cikin madaidaiciyar shugabanci na bututun axial surface, kuma a sanya su a cikin matsayi na kwance na axial surface a cikin kewayon ± 45 ° don hana sabon abu na bututu marasa gamsuwa, kumfa. ko hazo a saman ɓangaren firikwensin don rinjayar ma'auni na al'ada.Idan ba za a iya shigar da shi a kwance da kuma daidaitacce ba saboda iyakancewar sararin samaniya na shigarwa, ultrasonic flowmeter na iya shigar da firikwensin a tsaye ko a kusurwa a ƙarƙashin yanayin cewa babban ɓangaren bututu ba shi da kumfa.
