Khoom Description
Vortex flowmeter yog ib hom tshiab flowmeter tsim los siv cov kua dej Kalman txoj cai. Qhov no series ntawm flowmeter muaj cov yam ntxwv ntawm cov qauv yooj yim, muaj kev ntseeg siab, siab raug, zoo repeatability, dav txaus thiab kub ntau yam, me me siab poob, los tiv thaiv kev co, thiab anti-aging.
Lub ntsuas dej ntws tsis cuam tshuam los ntawm cov kua dej kub, siab, viscosity, thiab muaj pes tsawg leeg nyob rau hauv Reynolds tus lej teev. Lub piezoelectric tivthaiv yog lub hauv paus tseem ceeb rau kev kuaj pom cov teeb liab hauv cov ntsuas dej ntws. Cov qauv, cov duab, cov khoom siv, thiab cov khoom siv lub cev ntawm cov khoom no muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm TSF hom flow meter. Pua pua ntawm cov ntsuas ntws tau sib sau ua ke siv cov khoom siv hauv German thiab tau ua pov thawj los ntawm cov neeg siv kom tau raws li cov kev qhia tshwj xeeb ntawm cov khoom zoo sib xws hauv lub teb chaws Yelemees. Cov ntsuas ntawm lub piezoelectric caij no yog: piezoelectric tooj d Ntau tshaj los yog sib npaug rau 53 * 10C / N, dielectric tas li ε ≈ 190, Curie kub Tc ≈ 380 degree, parallelism Tsawg dua los yog sib npaug li 5 μ.
Flowmeters tuaj yeem siv dav hauv kev lag luam xws li roj av, petrochemicals, lub teeb kev lag luam, metallurgy, tshuaj, papermaking, dej hauv nroog, thiab cua sov. Qhov no series ntawm ntws cov qhab nias ua ke tso saib thiab cov chaw taws teeb kis tau tus mob, tso zis pulse signals lossis analog signals yog siv ua ke nrog LCD loj screen ntse cov cuab yeej kom ua tiav qhov ntsuas kub, siab, thiab ntws tso tawm ntawm tib lub vijtsam, nrog ntau yam haujlwm xws li relay zaub. , lub sij hawm tsub zuj zuj, thiab cov ntaub ntawv keeb kwm query rau cov neeg siv xaiv los ntawm.
