Ang SV21 ay isang vortex flowmeter para sa liquid, gas, at steam service. Ang isang bluff body ay nag-shed ng alternating vortices habang ang fluid ay lumalampas; ang shedding frequency ay proporsyonal sa flow velocity, at ang meter ay binibilang ang vortices upang makuha ang volumetric flow. Ang body ay rated para sa medium temperatures mula minus 40 hanggang 250 degrees C bilang standard, na may optional ranges hanggang 350 degrees C, at gumagana sa working pressures hanggang 25 MPa o Class150 hanggang Class1500 flange ratings.
Labing-isang nominal size mula DN15 hanggang DN300 ang sumasaklaw sa small-bore at large-bore process lines, na may clamp at flange mounting. Ang detection probe ay 316L stainless steel at ang wetted parts ay 304 o 316L; ang process connection ay maaaring carbon steel, 304, 316, o 316L. Sa HART, Modbus, o Profibus communication at isang separate converter option, ang SV21 ay akma sa plant DCS, asset management, at remote monitoring.
Anong mga fluid ang maaaring i-meter ng SV21?
Ang SV21 ay sumusukat ng liquids, gases, at steam sa malawak na temperature at pressure envelope. Hindi ito angkop para sa multiphase flow, highly viscous fluids, o slurries na mag-da-damp sa vortex shedding.
Ano ang pagkakaiba ng SV21 at small-bore vortex meters?
Ang SV21 ay full-bore vortex meter mula DN15 hanggang DN300 na may clamp o flange mounting, ginagamit sa full-size process lines. Ang small-bore insertion-style vortex meters ay naka-target sa DN15 hanggang DN65 na may clamp connection at umaangkop sa small-bore o retrofit locations.
Kailangan ba ng SV21 ng temperature at pressure compensation?
Sa saturated steam ang meter ay nagbabasa ng mass flow nang walang compensation; sa superheated steam at gases ang SV21 ay sumusuporta sa temperature at pressure inputs upang kalkulahin ang standard o mass flow. Ang compensation feature ay bahagi ng optional temperature at pressure compensation type.
Maaari bang gumana ang SV21 sa mga lugar na may panganib ng pagsabog?
Oo. Ang SV21 ay available sa non-explosion-proof, intrinsic safety, at flameproof versions. I-tugma ang certification code sa hazardous area classification sa installation site.
