I-vortex flowmeter inokulinganisa ukuhamba kwerhasi, ulwelo kunye nomphunga, njengokuhamba kwevolumu, ukuhamba kobuninzi, ukuhamba kwevolumu, njl.Impembelelo yomlinganiso ilungile kwaye ukuchaneka kuphezulu. Luhlobo olusetyenziswa kakhulu lokulinganisa ulwelo kwimibhobho yemizi-mveliso kwaye ineziphumo zokulinganisa ezilungileyo.
Uluhlu lwemilinganiselo ye-vortex flowmeter inkulu, kwaye ifuthe kumlinganiso lincinci. Umzekelo, uxinizelelo lwamanzi, uxinzelelo, i-viscosity, njl.njl Ayizukuchaphazela umsebenzi womlinganiso we-vortex flowmeter, ngenxa yoko ukusebenza kusomelele kakhulu.
Uncedo lwe-vortex flowmeter luluhlu lwayo olukhulu lokulinganisa. Ukuthembeka okuphezulu, akukho kulondolozwa koomatshini, kuba akukho zixhobo zoomatshini. Ngale ndlela, nokuba ixesha lokulinganisa lide, iiparameter zokubonisa zinokuzinza ngokuthe gabalala. Ngoluvo loxinzelelo, inokusebenza kubushushu obuphantsi nakwindawo enobushushu obuphezulu ngokuziqhelanisa namandla. Phakathi kwezixhobo zokulinganisa ezifanayo, i-vortex flowmeter lolona khetho lufanelekileyo. Ngoku, iifektri ezininzi zisebenzisa olu hlobo lwesixhobo ukulinganisa ixabiso ngcono nangokuchanekileyo.
Umzekelo: 0.13-0.16 1 / L, unokuqikelela i-bai ngokwakho, ulinganise ububanzi bekholamu yonxantathu, kwaye ipharamitha yeStraw du Hall iphakathi kwe-0.16-0.23 (ibalwe ngo-0.17).
f = I-StV / d ifomula (1)
Apho dao:
f-Carman vortex frequency eveliswe kwelinye icala lomvelisi
Inombolo ye-St-Strohal (inombolo engenakubalwa)
V-umndilili wokuhamba kwenqanaba lolwelo
d-ububanzi bomvelisi we-vortex (qaphela iyunithi)
Emva kokubala ubungakanani
K = f * 3.6 / (v * D * D / 353.7)
K: ukuhamba ngokulingana
f: Ukuphindaphinda okwenziwe kwinqanaba lokuhamba okusetiweyo
D: Ukuhamba kwemilinganiselo yokulinganisa
V: Ukuhamba kwenqanaba
Uluhlu lwe-Vortex flowmeter yokukhetha
Umsebenzi kunye nohlobo lwesikhulisi samandla esimhlophe kunye nesixhobo sokukhulisa amandla eDu sevortex flowmeter zahlukile.
