Ukuchaneka kweMitha yokuHamba kweUltrasonic kunye noHlalutyo lweeMpazamo

Iimitha zokuhamba kwe-ultrasoniczixatyiswa kakhulu ngenxa yokungabi nangxaki, ukulula kokufakwa kwazo, kunye noluhlu olubanzi lwezicelo. Nangona kunjalo, njengazo zonke izixhobo zokulinganisa, ukuchaneka kweemitha zokuhamba nge-ultrasonic kunokuchatshazelwa zizinto ezininzi. Ukuqonda ezi zinto kunye nendlela yokunciphisa iziphumo zazo kubalulekile ukuqinisekisa ukulinganiswa kokuhamba okuthembekileyo nokuchanekileyo.

Olu xwebhu luza kubonelela ngohlalutyo olunzulu lwezinto eziphambili ezichaphazela ukuchaneka kweemitha zokuhamba kwe-ultrasonic kwaye lunike iingcebiso zokunciphisa iimpazamo.

1. Iimpawu zolwelo

Iimpawu zolwelo olulinganiswayo, ezinje nge-viscosity, i-density, kunye ne-acoustic impedance, zinokuba nefuthe elikhulu ekuchanekeni kokulinganisa kwee-ultrasound flow meters.

• Ukuqina kunye noxinano: Ulwelo olune-viscosity ephezulu, njengeoyile, lunokunciphisa isignali ye-ultrasonic, nto leyo ekhokelela ekuchanekeni okuphantsi. Ngokwahlukileyo koko, ulwelo olune-viscosity ephantsi, njengamanzi, ludla ngokubonelela ngokudluliselwa kwesignali okucacileyo. Ngokufanayo, uxinano lolwelo luchaphazela isantya sokusasazeka kwamaza e-ultrasound, nto leyo enokuphazamisa imilinganiselo ukuba ayibalwanga kakuhle.

• Impedance ye-Acoustic: Umahluko kwi-acoustic impedance phakathi kolwelo kunye nezinto zombhobho uchaphazela ukubonakaliswa kunye nokudluliselwa kwamaza e-ultrasonic. Ulwelo olune-acoustic impedance ephezulu okanye esezantsi kunezinto zombhobho lunokubangela ukungachaneki kwisantya sokuhamba esilinganisiweyo.

Ukunciphisa Iimpazamo:
Ukuze kuncitshiswe iimpazamo ezibangelwa ziimpawu zolwelo, imitha yokuhamba kwe-ultrasonic kufuneka ilinganiswe ngokukodwa ukuze ilungele ulwelo olusetyenziswayo.

Ukongeza, ii-flow meter zanamhlanje zihlala zixhotyiswe nge-algorithms eziphambili zokucubungula isignali ukucoca ingxolo nokuphucula ukuthembeka kokulinganisa.

6. Izinto zombhobho

Izinto ezikwipayipi zinokuchaphazela ukuchaneka kokulinganisa ukuhamba kwe-ultrasonic. Izinto ezahlukeneyo zine-acoustic impedances ezahlukeneyo, ezinokutshintsha ukusasazeka kwamaza e-ultrasound.

• Iipayipi zesinyithi vs. zeplastiki: Iipayipi zesinyithi ngokubanzi zibonelela ngokudluliselwa okungcono kwamaza e-ultrasonic nge-acoustic xa kuthelekiswa neepayipi zeplastiki. Nangona kunjalo, ukuba izinto zepayipi zinomahluko omkhulu kwi-acoustic impedance evela kulwelo, oku kunokukhokelela kwiimpazamo kwimilinganiselo yexesha lokubhabha.

Ukunciphisa Iimpazamo:
Ukuze kuqwalaselwe olu tshintsho, kubalulekile ukufaka izinto zombhobho ezichanekileyo kwizicwangciso zoqwalaselo lwemitha yokuhamba kwamanzi. Kwizinto zombhobho ezinzima ukulinganisa, kusetyenziswa ii-transducers ezikhethekileyo okanye ukusebenzisa izinto zokulungisa ezisekelwe kwidatha yobungqina kunokufuneka.

7. Izinto eziphathelele indalo

Iimeko zokusingqongileyo ezifana nokufuma, uxinzelelo lomoya, kunye namasimi e-electromagnetic nazo zinokuchaphazela ukusebenza kweemitha zokuhamba kwe-ultrasonic, nangona ezi ziphumo zihlala zincinci xa kuthelekiswa nezinto ezithile zolwelo.

Ukunciphisa Iimpazamo:
Izinto ezikwimo yendalo kufuneka ziqwalaselwe xa kubekwa i-flow meter, ingakumbi kwiindawo ezinokuba neemeko zemozulu ezigqithisileyo okanye ukuphazamiseka kwe-electromagnetic. Ii-ultrasonic flow meter ezininzi eziphambili ziquka iimpawu zokuhlawula imeko-bume ukunceda ukunciphisa impembelelo yezi zinto ziguquguqukayo.

Isiphelo
