1. Gabatarwa Taƙaitaccen Bayani

Mita kwararar fasahar ultrasonic ta ƙunshi kalkuleta da firikwensin ultrasonic. Na'urori masu auna ultrasonic da aka haɗa sun haɗa da firikwensin da ba ya shiga jiki, firikwensin sakawa da firikwensin da aka haɗa a bangon bututu na ciki ko ƙasan tashar.

Ana buƙatar a ɗora na'urorin transducer na ultrasonic a kan bangon waje na bututun da aka auna ta hanyar hanyoyin V, hanyar Z da hanyar W. Mita kwararar ultrasonic ta tashoshi biyu yayi kama da na tashoshi ɗaya. Bambancin da mita kwararar ultrasonic ta tashoshi ɗaya ke buƙatar na'urar firikwensin guda ɗaya don shigarwa, amma mita kwararar ultrasonic ta tashoshi biyu yana buƙatar na'urori masu auna firikwensin guda biyu don shigarwa. Ana manne na'urorin a waje kuma suna samun karatun kwarara kai tsaye ta bangon bututu. Daidaiton shine 0.5% da 1%. Na'urar firikwensin ultrasound na nau'in lokacin wucewa yayi kyau don auna ruwa mai tsabta da ƙanƙanta.

Ana buƙatar a ɗora manne a kan na'urorin transducer na ultrasonic na doppler a kan bututun waje kai tsaye a gaban juna kuma yana da kyau a auna ruwa mai datti, dole ne a sami wasu barbashi masu girma waɗanda za su iya haifar da hangen nesa na tsayi, barbashin ya kamata ya zama aƙalla microns 100 (inci 0.004) a diamita na 40mm-4000mm. Idan ruwan ya bayyana sosai, wannan nau'in mitar kwarara ba zai yi aiki da kyau ba.

Na'urar firikwensin saurin yanki yawanci ana haɗa ta da bangon bututun ciki ko kuma a sanya ta a ƙasan tashar. Ga na'urar firikwensin saurin yankinmu, ana buƙatar mafi ƙarancin matakin ruwa ya zama sama da 20mm ko sama da tsayin na'urar firikwensin, tsayin na'urar firikwensin shine 22mm, don tabbatar da daidaito mai kyau, ƙaramin matakin ruwa yana buƙatar ya kasance daga 40mm zuwa 50mm.

Domin tabbatar da daidaito mai kyau, duka nau'ikan mitoci suna buƙatar isasshen bututu madaidaiciya, yawanci, ya nemi aƙalla 10D na sama da ƙasa 5D, inda D shine diamita na bututu. Gilashin hannu, bawuloli, da sauran na'urori waɗanda ke damun kwararar laminar na iya rage daidaito sosai.

2. Yadda ake aiki don mitar kwararar ultrasonic na lokacin wucewa

Ga na'urar auna kwararar ruwa ta ultrasonic da ke cika bututun, suna aika sigina ga junansu, kuma motsin ruwa a cikin bututun yana haifar da bambanci mai aunawa a cikin lokacin wucewar sauti yayin da yake motsawa tare da kuma akan kwararar. Dangane da diamita na bututun, siginar na iya tafiya kai tsaye tsakanin na'urorin juyawa, ko kuma tana iya tsalle daga bango zuwa bango. Kamar fasahar Doppler, na'urar juyawa tana auna saurin kwarara, wanda ke fassara zuwa kwarara.

Na'urar auna gudu ta nau'in saurin yanki, Gudun Ruwa a kusa da na'urar auna DOF6000 ana auna ta hanyar sauti ta hanyar rikodin canjin Doppler daga barbashi da kumfa mai ƙananan iska da ake ɗauka a cikin ruwa. Zurfin Ruwa sama da na'urar auna DOF6000 ana auna shi ta hanyar matsi Mai aunawa yana rikodin matsin lamba na ruwa a sama da na'urar. Ana auna zafin jiki don inganta rikodin sauti. Waɗannan suna da alaƙa da saurin sauti a cikin ruwa, wanda zafin jiki ke shafar shi sosai. Ana ƙididdige ƙimar kwarara da jimlar ƙimar kwarara ta hanyar kalkuleta kwarara daga bayanin girman tashar da mai amfani ya ƙayyade.

3. Nau'ikan mitar kwararar ultrasonic

Fasahar lokacin wucewa: An saka ko an ɗora bango na TF1100-EC na dindindin, nau'in saka TF1100-EI, nau'in hannu na TF1100-CH da nau'in TF1100-EP mai ɗaukuwa;

Na'urar auna kwararar ruwa ta ultrasonic SC7/WM9100/Ultrawit mai inline, wacce ta haɗa da haɗin zare da haɗin flange.

Manne mai ɗaurewa na TF1100-DC a bango akan tashoshi biyu na na'urar auna kwararar ultrasonic, nau'in shigarwa na TF1100-DI tashoshi biyu na na'urar auna kwararar ultrasonic da kuma nau'in batirin TF1100-DP mai ɗaukuwa wanda ke sarrafa tashoshi biyu na na'urar auna kwararar ultrasonic.

Fasahar Doppler: An saka DF6100-EC a bango ko kuma an saka ta dindindin, nau'in saka DF6100-EI da nau'in DF6100-EP mai ɗaukuwa.

1. Fasahar Ultrasonic

2. A al'ada, mitar kwararar ultrasonic ta lokacin wucewa ta fi daidai fiye da mitar kwararar nau'in doppler.

3. Ba za a iya auna ruwa sama da 200℃ ba.

5. Iyakoki na gama gari

1. Don lokacin wucewa da kuma mitar kwararar ultrasonic na bututun doppler, dole ne bututun ya cika da ruwa ba tare da kumfa ba.

2. Don mannewa akan mitar kwararar ultrasonic, bututu dole ne su zama kayan da suka yi kama da juna waɗanda ke iya watsa sauti. Kayan aiki kamar siminti, FRP, bututun ƙarfe mai layi da filastik, da sauran abubuwan haɗin gwiwa suna hana yaɗuwar raƙuman sauti.

3. Ga na'urar auna kwararar ruwa ta ultrasonic wadda ba ta taɓawa, yawanci bai kamata ta kasance tana da ma'ajiyar ciki ba, kuma dole ne saman waje ya kasance mai tsabta inda na'urar ta ɗora. Ana iya taimakawa wajen watsa sauti ta hanyar sanya mai ko wani abu makamancin haka a kan hanyar da ke tare da bangon bututun.

4. Ga na'urar auna kwararar ultrasonic wadda ba ta da illa, ya fi kyau a ɗora na'urorin transducers a gefunan bututun a matsayi na 3:00 da 9:00, maimakon sama da ƙasa. Wannan yana hana duk wani laka a ƙasan bututun.
