Differential Pressure Level Measurement: Kusarudza Pakati
Single uye Kaviri Flange Transmitters
Kana zvasvika pakuyera mazinga emvura mumatangi emaindasitiri - kunyanya ayo ane viscous, corrosive, kana crystallizing midhiya - musiyano wekumanikidza level transmitters mhinduro yakavimbika. Zvichienderana nedhizaini yetangi uye mamiriro ekumanikidza, maviri makuru masisitimu anoshandiswa: single-flange uye maviri-flange transmitters.
Nguva Yekushandisa Single-Flange Transmitters
Single-flange transmitters yakanakira matangi akavhurika kana akavharwa zvishoma. Ivo vanoyera hydrostatic kudzvinyirirwa kubva kumvura mbiru, vachiishandura kusvika padanho zvichienderana neiyo inozivikanwa fluid density. Iyo transmitter inoiswa pazasi petangi, ine yakaderera-kudzvanywa chiteshi ichienda kumhepo.
Muenzaniso: Tangi kureba = 3175 mm, mvura (density = 1 g/cm³)
Kudzvanyirirwa ≈ 6.23 kusvika 37.37 kPa
Kuti uve nechokwadi chekuverenga chaiko, zvakakosha kuti ugadzirise zero kukwidziridzwa zvakanaka kana iyo shoma yemvura level iri pamusoro pepombi yekutumira.
Nguva Yekushandisa Double-Flange Transmitters
Kaviri-flange transmitters akagadzirirwa akavharwa kana kumanikidzwa matangi. Mativi ese ari maviri akakwira- uye akaderera-anodzvanya akabatana kuburikidza neari kure diaphragm seals uye capillaries.
Kune maviri setups:
- Dry gumbo:Zvemafutsi asingadziviriri
- Gumbo rakanyorova:Pakukwirisa mhute, inoda pre-yakazadzwa sealing fluid mumutsetse wepasi-pressure
Muenzaniso: 2450 mm fluid level, 3800 mm capillary kuzadza urefu
Range inogona kuva -31.04 kusvika -6.13 kPa
Mumagadzirirwo emakumbo akanyorova, kudzvinyirira zero zvisina kunaka kunodiwa.
Installation Best Practices
- • Pamatangi akavhurika, gara uchiburitsa L port kumhepo
- • Pamatangi akavharwa, dzvinyiriro yereferensi kana makumbo akanyorova anofanira kugadzirwa zvichienderana nemaitiro emhute
- • Chengeta macapillaries akaunganidzwa uye akagadziriswa kuderedza mhedzisiro yezvakatipoteredza
- • Mutapurisa anofanirwa kuiswa 600 mm pazasi peyakanyanya-pressure diaphragm kuti isa stable head pressure.
- • Dzivisa kusungirira pamusoro pechisimbiso kunze kwekunge wanyatsoverengerwa
Differential pressure transmitters ine flange dhizaini inopa kurongeka kwepamusoro uye kuvimbika mumiti yemakemikari, masisitimu emagetsi, uye zvikamu zvezvakatipoteredza. Kusarudza kurongeka kwakakodzera kunovimbisa kuchengetedzeka, kushanda zvakanaka kwemaitiro, uye kugadzikana kwenguva refu mumamiriro ezvinhu akaoma maindasitiri.
