Poyerekeza ndi mitundu ina ya ma ultrasound flowmeters, external clamp ultrasonic flowmeter ili ndi ubwino wosayerekezeka. Mwachitsanzo, external clamp type ultra-side flowmeter imatha kuyika probe pamwamba pa chitoliro, kuti madzi asasweke ndipo madziwo ayezedwe potengera kuti sanaswe chitolirocho. Kuphatikiza apo, kutayika kwake kwa kuthamanga ndi kochepa, pafupifupi zero, ndipo ilinso ndi mwayi waukulu pankhani ya mtengo pamsika wa ultrasound flowmeters waukulu, ndipo yalandira matamando ambiri kuchokera kwa makasitomala.
Komabe, kwenikweni, pakugwiritsa ntchito kwenikweni kwa ultrasound clamp flowmeter, padzakhala zifukwa zosalondola zoyezera kuchokera kwa makasitomala. Ndipotu, vutoli nthawi zambiri limakhala loti wogwiritsa ntchito nthawi yokhazikitsa amanyalanyaza mavuto awa, lero talemba chimodzi mwa izo kuti tikufotokozereni.
Chomangirira chakunja cha flowmeter ya ultrasonic sichinatsimikizidwe bwino kapena kuyesedwa bwino, ndipo tifunika kudziwa kuti flowmeter iliyonse iyenera kutsimikiziridwa kapena kuyesedwa bwino musanagwiritse ntchito. Pakulinganiza kapena kulinganiza, kuchuluka kwa flow rate ndikofunikira, kusankha flowmeter yomwe imapereka flow rate yokhazikika ndikofunikira kwambiri.
Ma flow meter onyamulika a ultrasonic nthawi zambiri amakhala ndi ma probe atatu oti asankhe, ma probe atatuwa, motsatana, oyenera ma payipi osiyanasiyana, ma probe osiyanasiyana okhala ndi host m'lingaliro lokhala ndi ma flow meter odziyimira pawokha. Pa flow calibration, zida zoyezera ma flow meter okhala ndi ma payipi osiyanasiyana ziyenera kugwiritsidwa ntchito poyezera ma payipi onse atatu, ndipo ma payipi meter a chipangizo choyezera ma meter ayenera kufananizidwa ndi ma payipi oyezera ma meter.
Njira yolondola yotsimikizira imachokera pa momwe wogwiritsa ntchito amagwiritsira ntchito ngati chitsogozo, momwe angathere, choyezera kuyenda kwa ultrasonic chonyamulika chimayezedwa kapena kukonzedwa pa chipangizo choyezera kuyenda chomwe chili ndi mulifupi wofanana kapena pafupi ndi chitolirocho, ndikuwonetsetsa kuti gulu lililonse la ma probe a kasinthidwe ka flowmeter layang'aniridwa, ndipo zolemba za calibrating aperture ndi nambala ya probe zalembedwa bwino kuti zisamveke bwino.
Choyezera madzi cha Ultrasonic chili ndi zofunikira zina pa momwe chigwiritsidwe ntchito komanso malo ogwiritsira ntchito malo, ndipo chiyenera kugwiritsidwa ntchito pamene zinthuzo zakwaniritsidwa. Ngati malo oyikapo a choyezera madzi cha Ultrasonic sangakwaniritse zofunikira za kutalika kwa gawo la chitoliro chakutsogolo ndi chakumbuyo, padzakhala zolakwika zoyezera chifukwa cha kusakhazikika kwa malo. Ogwiritsa ntchito ambiri adzachepetsedwa ndi chida choyezera chitsime akamagwiritsa ntchito, ndipo sangathe kukwaniritsa zofunikira za malo oyikapo, zomwe zidzakhala ndi zolakwika zazikulu zoyezera.
Kuphatikiza apo, choyezera mpweya chakunja cha clamp cha njira yosiyana ndi nthawi chimakhala chodziwika bwino ndi thovu losakanizidwa mu measurement, ndipo thovulo limapangitsa kuti mtengo wosonyeza mpweya wa flowmeter ukhale wosakhazikika. Ngati mpweya wosonkhanitsidwa upezeka pamalo oyikapo probe, choyezera mpweya sichigwira ntchito. Chifukwa chake, malo oyikapo mpweya wakunja wa clamp sayenera kupewedwa momwe zingathere kuchokera pamalo otulutsira mpweya, mphamvu yamphamvu ya maginito ndi mphamvu yamagetsi, komanso malo okwera a payipi.
Malo oyikapo chipangizo choyezera kuyenda kwa madzi (ultrasonic flowmeter probe) ayeneranso kupewa kumtunda ndi pansi pa payipi momwe angathere, ndipo amaikidwa mkati mwa ngodya ya 45° yokhala ndi mainchesi opingasa, ndipo malo oyikapo amafunika kupewa zolakwika za mapaipi monga ma weld. Nthawi yomweyo, ma ultrasound flow meter sali oyenera kuyikidwa m'mbali mwa msewu wa magalimoto odzaza, ndipo yesetsani kupewa kugwiritsa ntchito mafoni am'manja kapena ma walkie-talkies pafupi ndi malo osungira.
Pakutumikira makasitomala kwa zaka zambiri, nthawi zambiri pamakhala makasitomala omwe amauza kampani yathu kuti kulondola kwa ultrasound flowmeter yakunja sikulondola. Ndipotu, kulondola kolakwika kwa flowmeter kumakumananso ndi mavuto omwe makasitomala akugwiritsa ntchito, monga kusayesa molondola magawo a payipi kudzakhala ndi zotsatirapo zazikulu pa kulondola kwa muyeso.
Sizingatheke kuyeza molondola magawo a payipi zomwe zimapangitsa kuti muyeso ukhale wolakwika, chipangizo choyezera kuyenda kwa madzi chonyamulika chomwe chimayendetsedwa ndi ultrasonic chimayikidwa kunja kwa payipi, chomwe chimayesa mwachindunji kuyenda kwa madzi mu payipi. Kuthamanga kumeneku kumakhudzidwa ndi kuchuluka kwa kuyenda ndi dera la kuyenda kwa payipi (m'mimba mwake wamkati mwa payipi), ndipo deta ndi chinthu chomwe chimapangidwa. Malo a payipi ndi kutalika kwa njira zimawerengedwa ndi magawo a payipi omwe wogwiritsa ntchito amalowetsa pamanja. Kulondola kwa magawo awa kudzakhudza mwachindunji zotsatira za muyeso.
Kumbali ina, ngakhale ngati mita yoyezera madzi yokha si vuto, koma ngati deta ya mapaipi olowera ogwiritsa ntchito si yolondola, zotsatira za muyeso sizolondola, muyeso wa magawo a mapaipi nthawi zambiri umakhala wokondera, ndipo makulidwe a khoma la mapaipi adzasintha pambuyo pa nthawi yogwiritsidwa ntchito, kotero cholakwika cha deta yoyezera sichingapeweke.
Chifukwa chake, poyesa deta ya m'mimba mwake wa chitoliro, tiyeneranso kulabadira kumveka bwino kwa njirayo, ndipo zida zoyezera ziyeneranso kuyesedwa. Poyesa deta iyi, tiyenera kulabadira kwambiri momwe gawo lakunja lotetezera la chitolirocho limakhudzira komanso dzimbiri ndi dothi lakunja kwa pamwamba pa deta yoyezera.
