Vortex flowmeter imatha kuyeza kutuluka kwa gasi, madzi ndi nthunzi, monga kuthamanga kwa voliyumu, kutuluka kwamphamvu, kuthamanga kwa voliyumu, ndi zina. Zotsatira zake ndi zabwino ndipo kulondola kwake ndikokwera. Ndiwo mtundu wamagetsi womwe umagwiritsidwa ntchito kwambiri pamapayipi amakampani ndipo uli ndi zotsatira zoyesa zabwino.
Mulingo woyeserera wa flowmeter wa vortex ndi waukulu, ndipo mphamvu yake pamiyeso ndi yaying'ono. Mwachitsanzo, kuchepa kwamadzimadzi, kuthamanga, mamasukidwe akayendedwe, ndi zina zambiri sizingakhudze magwiridwe antchito a vortex flowmeter, chifukwa chake kuthekera kumakhala kolimba kwambiri.
Ubwino wa vortex flowmeter ndiyeso yayikulu yoyezera. Kudalirika kwambiri, osasamalira makina, chifukwa palibe magawo amakina. Mwanjira iyi, ngakhale nthawi yoyezera ndiyitali, magawo owonetsera akhoza kukhala osakhazikika. Ndi mphamvu yamagetsi, imatha kugwira ntchito m'malo otentha komanso otentha kwambiri. Mwa zida zofananira zofananira, njira yoyenda ndi vortex ndiye chisankho chabwino. Tsopano, mafakitale ambiri amagwiritsa ntchito chida chamtunduwu kuti ayese kufunika bwino komanso molondola.
Mwachitsanzo: 0.13-0.16 1 / L, mutha kuyerekezera bai nokha, muyese m'lifupi mwake pakhomopo, ndipo gawo la Straw du Hall lili pakati pa 0.16-0.23 (lowerengedwa pa 0.17).
f = Njira ya StV / d (1)
Kumene Dao:
f-Carman vortex pafupipafupi yopangidwa mbali imodzi ya jenereta
St-Strohal nambala (yopanda malire)
V - kuchuluka kwakumwa kwamadzimadzi
d-m'lifupi mwa jenereta ya vortex (onani unit)
Pambuyo powerengera pafupipafupi
K = f * 3.6 / (v * D * D / 353.7)
K: koyefishienti yoyenda
f: Mafupipafupi omwe amapangidwa pamlingo wokhazikika
D: Kutalika kwa mita
V: Mulingo woyenda
Vortex flowmeter osiyanasiyana kusankha
Ntchito ndi mtundu wa zoyera zamagetsi zoyera ndi mphamvu yamagetsi ya Du yamagetsi yotulutsa vortex ndiyosiyana.

1. Vortex flowmeter yokhala ndi ntchito zosavuta imaphatikizapo izi:
Chowongolera chamagetsi, chodula chazing'ono, chofananira ndi 4-20mA, kuchuluka kwa zitsanzo kapena nthawi yodziwonetsera, kudzikundikira, ndi zina zambiri.
2. Kuphatikiza apo, flowmeter wathunthu wa vortex imaphatikizaponso izi:
Kuyeza mtundu wapakatikati, kulowa kwa chipukuta misozi, gawo loyenda, mtundu wazizindikiro, kutentha kumtunda ndi kutsika, kuthamanga kumtunda ndi kutsika, kuthamanga kwapakatikati, kupsinjika kwapakatikati, kulumikizana.
