Yintoni i-clamp kwi-ultrasonic flow meter?

Isixhobo sokulinganisa ukuhamba kwe-ultrasonic esibizwa ngokuba yi-clamp-on sisixhobo esingangenisi gazi esisetyenziselwa ukulinganisa isantya sokuhamba kolwelo okanye iigesi kumbhobho. Endaweni yokufakelwa ngqo kumbhobho, ii-transducers ze-ultrasonic zibotshelelwa ngaphandle kombhobho. Ezi mitha zisebenza ngokusebenzisa amaza esandi se-ultrasonic ukulinganisa isantya solwelo oluhamba kumbhobho.

Ingaba isebenza kanjani:
1. Iitransducer ze-Ultrasonic: Iitransducer ezimbini zibekwe kumacala ahlukeneyo ombhobho. Zisebenza njengeetransmitter kunye nezamkeli zemiqondiso ye-ultrasound.
2. Umgaqo wexesha lokuThutha:
• Imitha ithumela ii-pulses ze-ultrasonic kumacala omabini—ezantsi (ngokuhamba) naphezulu (ngokuchasene nokuhamba).
• Ixesha elithathwayo ukuze isignali ihambe iye ezantsi komsinga lifutshane kunelo lihamba phezulu komsinga.
• Umahluko kwixesha lokuhamba uhambelana ngqo nesantya sokuhamba kolwelo.
3. Umgaqo weDoppler (ukhetho):
• Ezinye iimodeli zisebenzisa i-Doppler effect ngokutsiba amaza esandi kwiinxalenye okanye amaqamza kulwelo. Utshintsho lwefrikhwensi phakathi kwemiqondiso edluliselweyo neyamkelweyo lusetyenziselwa ukubala isantya sokuhamba.
4. Ukubalwa koMsinga:
• Imitha yokuhamba kwamanzi isebenzisa isantya sokuhamba esilinganisiweyo kunye nommandla onqamlezileyo wombhobho ukuze kubalwe isantya sokuhamba kwamanzi esinomthamo.

Iingenelo:
• Ayingenisi: Akukho mfuneko yokusika umbhobho, ukuthintela ukuphazamiseka kokuhamba kwamanzi kunye nongcoliseko.
• Isebenza ngeendlela ezahlukeneyo: Isebenza kwizinto ezahlukeneyo zepayipi (isinyithi, iplastiki, njl.njl.) kunye nobukhulu.
• Iyaphatheka: Isetyenziswa rhoqo ekulinganiseni okwethutyana okanye amabala.
• Ulondolozo oluncinci: Akukho zixhobo zishukumayo ezinciphisa ukuguguleka nokukrazuka.

Imida:
• Iimpawu zolwelo: Zisebenza kakuhle kwizinto ezicocekileyo okanye ezo ziqulethe amasuntswana amancinci, ahambelanayo okanye amaqamza kwiimodeli zeDoppler.
• Iimeko zePipe: Ukuchaneka kunokuchaphazeleka zizinto zepipe, ubukhulu, kunye neemeko zangaphakathi (umz., ukukala okanye ukugqwala).

Iimitha zokuhamba ze-ultrasonic ezibizwa ngokuba yi-Clamp-on zisetyenziswa kakhulu kumashishini afana nonyango lwamanzi, ioyile negesi, i-HVAC, kunye nokucubungula iikhemikhali kwiimfuno zokulinganisa ukuhamba okusisigxina nokwexeshana.
