Iimpawu zeeMeter ze-Transit Time Clamp-On Ultrasonic Flow Meters

Imitha yokuhamba kwe-ultrasonic ebambekayo ngexesha lokuhamba sisixhobo esisetyenziswa kakhulu ekulinganiseni ukuhamba okungengongeneleli. Isebenzisa itekhnoloji ye-ultrasonic ephucukileyo, ilinganisa izinga lokuhamba kolwelo kwimibhobho evaliweyo ngokuhlalutya umahluko wexesha wemiqondiso ye-ultrasonic edluliselwa phezulu nasezantsi. Uyilo lwayo olutsha kunye neenzuzo ezisebenzayo zenza ukuba ibe sisisombululo esifanelekileyo kumashishini ahlukeneyo. Ngezantsi, sihlola iimpawu eziphambili zesi sixhobo esinokusetyenziswa ngeendlela ezahlukeneyo:

1. Uyilo olungaphazamisiyo

Enye yezona zinto zibalaseleyo zee-clamp-on ultrasonic flow meter kukuba aziphazamisi. Ezi meter zifakelwa ngaphandle kumbhobho, azidingi kudibana ngokwasemzimbeni nolwelo. Olu yilo:
• Isusa isidingo sokusika okanye sokutshintsha umbhobho.
• Ithintela ungcoliseko, nto leyo eyenza ukuba ilungele ukusetyenziswa kococeko nobuthathaka njengokutya, iziselo, kunye namayeza.
• Ivumela ukufakwa ngaphandle kwexesha lokungasebenzi kwenkqubo okanye ukuphazamiseka kwenkqubo.

3. Umlinganiselo ochanekileyo nothembekileyo

Umgaqo wexesha lokuhamba uqinisekisa ukulinganiswa kokuhamba okuchanekileyo kakhulu, ngokuqhelekileyo kufikelela kwinqanaba lokuchaneka le-±0.5% okanye ngaphezulu. Ulinganisa umahluko kumaxesha okuhamba kwee-pulses ze-ultrasonic ezihamba kunye nokuchaneka kokuhamba kolwelo. Iimpawu ezinegalelo ekuchanekeni kwalo ziquka:
• Ukulungiswa kwesignali okuphucukileyo ukuze kujongwane neemeko zokuhamba okuguquguqukayo.
• Ukukwazi ukulinganisa uluhlu olubanzi lwamazinga okuhamba kwamanzi.
• Ukuhambelana nolwelo olucocekileyo kunye nolwelo olungcolisekileyo kancinci, ukuba nje amanqanaba ongcoliseko aphantsi.

4. Uluhlu olubanzi lwezicelo

Ezi mitha zilungele ukusetyenziswa ngeendlela ezahlukeneyo, njengoko zinokulinganisa iintlobo ezahlukeneyo zolwelo, kuquka:
• Amanzi (acociweyo, aluhlaza, okanye amdaka).
• Iikhemikhali.
• Iioyile.
• Ezinye izinto ezimanzi ezingaxineneyo.

Ukuguquguquka kwazo kuxhomekeke ekubeni zikwazi ukusebenza ngezinto ezahlukeneyo zepayipi ezifana nesinyithi, i-PVC, kunye nezinto ezidityanisiweyo, nakwiidayamitha ezahlukeneyo zepayipi.

5. Ukufakwa kunye nokugcinwa lula

Uyilo lwe-clamp-on lwenza kube lula ukufaka, kuba akukho mfuneko yokutshintsha imibhobho okanye ukucima inkqubo. Ukugcinwa kwayo kulula kakhulu:
• Ukungabikho kweendawo ezishukumayo kuthetha ukunciphisa ukuguguleka nokukrazuka.
• Izinzwa zihlala zingaphandle, nto leyo enciphisa umngcipheko wokungcola, ukugqwala, okanye ukukrala.
Oku kukhokelela ekuncipheni kweendleko zokusebenza kunye nexesha lokungasebenzi ngexesha lokusetyenziswa kwesixhobo.

6. Iinketho Eziphathekayo Nezingaguqukiyo

Iimitha zokuhamba ze-ultrasonic zexesha lokuhamba ziza ngeendlela eziphathekayo nezizinzileyo, zilungele iimfuno ezahlukeneyo:
• IiMeter zokuhamba eziphathwayo: Zilula kwaye zincinci, zilungele ukufakwa okwethutyana okanye iinjongo zokuxilonga.
• IiMeter zoMsinga eziZinzileyo: Ukufakelwa okusisigxina kokujonga rhoqo ukuhamba kwamanzi kwiinkqubo ezibalulekileyo.

7. Ukulinganisa iiNdlela ezimbini

Inzuzo ebalulekileyo yeemitha zokuhamba nge-ultrasonic ngexesha lokuhamba kukuba ziyakwazi ukulinganisa ukuhamba kuzo zombini iindlela. Oku kuzenza zibe nokuguquguquka kwiindawo apho ukuguquka kokuhamba kunokwenzeka khona, njengakwiinkqubo ze-hydraulic okanye iinkqubo zokumpompa eziya kwicala elinye.

8. Iziphumo zeDatha eziPhambili kunye noNxibelelwano

Iimitha zokuhamba ze-ultrasonic zanamhlanje zixhotyiswe ngezakhono zonxibelelwano eziphambili, ezifana nezi:
• Iinketho zedijithali kunye ne-analog output (umz., 4-20 mA, pulse, okanye iModbus).
• Ukugcinwa kwedatha ukuze kuhlalutywe ukuhamba kwexesha elide.
• Ukuhlanganiswa ne-SCADA kunye nezinye iinkqubo zokubeka esweni.
