Iingenelo zeCoriolis mass flowmeters

Ii-flowmeters zobunzima beCoriolis, ezilinganisa ngokuthe ngqo ukuhamba kobunzima bolwelo ngokusekelwe kwisiphumo seCoriolis, zizixhobo ezichanekileyo kakhulu ezineenzuzo ezilandelayo eziphambili:

1. Ukulinganisa ukuhamba kobunzima ngokuthe ngqo ngaphandle kwembuyekezo

• Zikhupha ngokuthe ngqo ukuhamba kobunzima (iiyunithi: kg/h, t/h, njl.njl.) kwaye azichaphazeleki lutshintsho kwiiparameter zolwelo ezifana nobushushu, uxinzelelo, uxinano, kunye ne-viscosity. Akukho zixhobo zongezelelweyo zokuhlawula ubushushu/uxinzelelo ezifunekayo, ukuqinisekisa ukuchaneka kokulinganisa okuzinzileyo.
• Xa kuthelekiswa nee-volumetric flowmeters (umz., i-vortex shedding, ii-orifice plates), ziphepha iimpazamo zokulinganisa ezibangelwa lutshintsho kwimeko yolwelo, nto leyo ezenza zifaneleke ngakumbi kwii-multi-component mixed fluids okanye ii-phase-change fluids (ezifana nee-liquids eziqulethe amaqamza).

2. Ukuchaneka komlinganiselo ophezulu kunye nokuphindaphinda okugqwesileyo

• Iimveliso ezikumgangatho wemizi-mveliso zihlala zifikelela ekuchanekeni kokulinganisa ukusuka ku-±0.1% ukuya ku-±0.5% yokufunda, kwaye iimodeli ezichanekileyo kakhulu zinokufikelela ku-±0.05%, zidlula kakhulu ezinye iintlobo zee-flowmeters.
• Zibonelela ngokuphindaphindwa okugqwesileyo (ngokubanzi ≤±0.05%) kunye nozinzo oluqinileyo lokusebenza ixesha elide, nto leyo ezenza zifaneleke kwiimeko ezineemfuno eziphezulu zokuthembeka kwedatha, ezifana nokulungiswa korhwebo kunye nolawulo lwenkqubo yokuchaneka.

3. Uluhlu olubanzi lweziselo ezifanelekileyo

• Banokulinganisa phantse zonke iintlobo zolwelo:
  • Ulwelo (kuquka ulwelo olunobumanzi obuphezulu, ulwelo oluneziqwenga, ulwelo olubolayo, njl.njl.);
  • Iigesi (kuquka iigesi ezinoxinzelelo oluphezulu, iigesi ezimanzi, iigesi ezixutyiweyo ezinamacandelo amaninzi);
  • Ukuhamba kwegesi-ulwelo okunezigaba ezimbini (ukugcina ukuchaneka ngaphakathi koluhlu oluthile lomlinganiselo).

4. Uyilo lwendlela yokuhamba engenanto ithintelayo

• Akukho zinto zishukumayo, iiturbine, okanye ezinye iindawo ezihambayo ngaphakathi kwisensor. Umlinganiselo ufezekiswa kuphela ngokungcangcazela kombhobho ngokwawo. Ke ngoko:
  • Ukulahlekelwa koxinzelelo kuncinci, nto leyo ebangela ukusetyenziswa kwamandla okuphantsi;
  • Azikwazi ukuvaleka, nto leyo enciphisa iindleko zokugcinwa, ingakumbi ezifanelekileyo kwiziselo eziqulethe ukungcola okanye i-viscosity ephezulu;
  • Zinobomi obude benkonzo, nto leyo enciphisa ukuwohloka kokuchaneka okubangelwa kukuguguleka kwezixhobo.

5. Ubuchule bokulinganisa iiparameter ezininzi ngaxeshanye

• Ukongeza ekuhambeni kobunzima, uninzi lweemodeli zinokukhupha iiparameters ezinje ngobuninzi bolwelo kunye nobushushu, zifikelele "kwimitha enye yokusetyenziswa okuninzi". Oku kwenza kube lula ulwakhiwo lwenkqubo kwaye kunciphisa iindleko zezixhobo.
• Ukuchaneka komlinganiselo woxinano kunokufikelela kwi-±0.001 g/cm³, nto leyo enokusetyenziselwa ukujonga uxinano lolwelo (umz., umxholo oqinileyo kwisiraphu okanye eludakeni).

6. Ufakelo nolondolozo olulula

• Zineemfuno eziphantsi zamacandelo eepayipi ezithe tye, nto leyo esusa isidingo sokuhamba kweepayipi ezithe tye ezinde phezulu nasezantsi, nto leyo eyenza kube lula ukubekwa kweendawo.
• Ukuba akukho zinto zishukumayo, izinga lokusilela liphantsi, nto leyo enciphisa amaxesha okugcinwa nokutshintshwa, kwaye inciphisa iindleko zizonke zobunini.
