O le vortex flowmeter mafai ona fuaina le tafe o kesi, suavai ma ausa, e pei o le tele o tafe, tele tafe, tele tafe, ma isi O le fua aafiaga e lelei ma o le saʻo e maualuga. O le sili ona lautele faʻaaogaina ituaiga o suavai fua i alamanuia paipa ma e lelei fua faʻaiuga.
O le fua o le vortex flowmeter e tele, ma o le aʻafiaga i le fua e laʻititi. Mo se faʻataʻitaʻiga, suavai density, mamafa, viscosity, ma isi mea o le a le aʻafia ai le fuaina gaioiga o le vortex flowmeter, o lea o le gaioiga o loʻo matua malosi lava.
O le lelei o le vortex flowmeter o lona tele fua fua. Maualuga faʻatuatuaina, leai ni masini faʻaleleia, aua e leai ni masini vaega. I lenei auala, tusa lava pe umi le taimi e fua ai, e mafai ona faʻamautu lelei le faʻaaliga faʻaali. Faatasi ai ma le uunaiga sensor, e mafai ona galue i le maualalo vevela ma maualuga vevela siosiomaga ma malosi fetuutuunai. Faʻatasi ai ma meafaigaluega fua tutusa, o le vortex flowmeter o le sili lelei filifiliga. Lenei, tele falegaosimea faʻaaoga lenei ituaiga mea faigaluega e fua ai le taua sili atu ma sili atu le saʻo.
Mo se faʻataʻitaʻiga: 0.13-0.16 1 / L, e mafai ona e fuafuaina le oe lava oe, fua le lautele o le koluma tafatolu, ma le Straw du Hall parameter o loʻo i le va o 0.16-0.23 (fuafuaina i le 0.17).
f = StV / d fuafaatatau (1)
Lea mea:
f-Carman vortex taimi masani na tupu i le tasi itu o le afi eletise
Numera St-Strohal (numera leai se mea)
V-o le averesi o le tafe o fua o le suavai
d-o le lautele o le vortex generator (tusi le iunite)
A maeʻa ona fuafua le alualu i luma
K = f * 3.6 / (v * D * D / 353.7)
K: tafe lelei
f: Faʻafia na tupu i le seti o le tafe
D: Fua mita mita
V: Fua faatatau o le tafe
Vortex flowmeter tele filifiliga
O le gaioiga ma le faʻamatalaga o le paʻepaʻe mana amplifier ma Du mana amplifier o le vortex flowmeter e eseese.
