1. Cov txiaj ntsig ntawm kev ntsuas qhov tseem ceeb

• Kev ntsuas qhov tseeb siab: Qhov tseeb ib txwm muaj txij li ±1.0% txog ±1.5% FS (±0.5% FS rau cov qauv siab), nrog rau qhov yuam kev rov ua dua ≤0.3%, ua tau raws li qhov yuav tsum tau ua ntawm kev daws teeb meem kev lag luam thiab kev tswj cov txheej txheem.
• Qhov piv ntawm kev tig rov qab dav: Qhov piv txwv txheem yog 1:10 txog 1:20, nthuav dav mus txog 1:30 rau qee cov qauv, npog kev ntsuas ntau yam kev ntws (piv txwv li, cov pa dej ntws los ntawm qhov tsawg mus rau qhov puv).
• Kev hloov pauv tau dav dav ntawm cov khoom siv nruab nrab: Muaj peev xwm ntsuas peb hom khoom siv nruab nrab - roj (roj av, nitrogen, cua compressed, thiab lwm yam), kua (dej, roj, cov tshuaj solvents, thiab lwm yam), thiab pa (pas saturated/superheated) - yam tsis tas hloov cov khoom tseem ceeb rau cov khoom siv nruab nrab sib txawv.

2. Cov yam ntxwv ntawm kev tsim kho thiab kev teeb tsa

• Tsis muaj qhov txav mus los: Lub ntsuas tseem ceeb tsis muaj cov khoom siv tig lossis hnav tau, ua rau muaj qhov tsis ua haujlwm tsawg thiab lub neej ntev (5 ~ 10 xyoo nyob rau hauv cov xwm txheej ib txwm muaj) nrog cov nqi kho tsawg kawg nkaus.
• Kev poob siab tsawg: Kev tiv taus cov kua dej tsuas yog 1/3 ~ 1/5 ntawm cov orifice flowmeters, txo cov dej poob zog, tshwj xeeb tshaj yog rau cov ntawv thov loj thiab qis siab.
• Kev teeb tsa yooj yim: Txhawb kev teeb tsa kab rov tav, ntsug, thiab inclined, nrog rau cov kav dej ncaj nraim uas tsis xoob (feem ntau yog 10D upstream / 5D downstream; qee cov qauv nrog cov qauv rectifier tuaj yeem luv dua rau 5D upstream / 3D downstream, qhov twg D = txoj kab uas hla ntawm cov yeeb nkab), kom ntseeg tau tias muaj kev hloov pauv zoo hauv qhov chaw.
• Cov qauv compact: Me me thiab lub teeb yuag, zoo tagnrho rau qhov chaw txwv tsis pub muaj (piv txwv li, chav khoom siv nqaim, cov kav dej siab).

3. Kev Hloov Kho Kev Ua Haujlwm

• Kev tiv taus kub thiab siab: Cov qauv txheem tiv taus -40 ℃ ~ 350 ℃ thiab ≤4.0MPa; cov qauv kev cai tuaj yeem txuas ntxiv mus txog 500 ℃ thiab 16MPa, tsim nyog rau kev ntsuas cov pa thiab cov kua dej kub.
• Muaj peev xwm tiv thaiv kev cuam tshuam zoo: Nruab nrog piezoelectric lossis capacitive sensors ua ke nrog cov thev naus laus zis digital filtering, zoo tiv taus kev co ntawm cov kav dej, kev cuam tshuam electromagnetic, thiab nruab nrab pulsation (qee cov qauv muaj kev tsim qauv tiv thaiv kev co, nrog kev co-induced yuam kev ≤ ± 0.1% FS).
• Cov kev xaiv tiv thaiv xeb/hnav: Rau cov xov xwm tshwj xeeb (cov kua qaub-raws li, cov pa plua plav), cov ntaub ntawv xws li hlau tsis xeb, PTFE hauv ob sab phlu, thiab Hastelloy muaj los nthuav cov xwm txheej thov.

4. Cov Kev Zoo ntawm Kev Ua Haujlwm & Kev Txij Nkawm

• Tsis tas yuav tsum tau kho qhov chaw: Raws li cov ntsiab cai ntsuas lub cev, kev kho qhov chaw hauv Hoobkas nrog cov khoom siv txheem tshem tawm qhov xav tau rov kho qhov chaw (muab cov ntsuas nruab nrab phim cov xwm txheej kho qhov chaw).
• Cov teeb liab nplua nuj: Txhawb nqa 4 ~ 20mA analog teeb liab, pulse teeb liab, thiab RS485 (Modbus protocol) cov teeb liab digital, txuas ncaj qha rau PLC, DCS systems, lossis cov khoom siv tau cov ntaub ntawv rau kev tswj hwm tsis siv neeg.
• Tus nqi ua haujlwm qis: Tsis tas yuav siv cov khoom siv lossis kev rhuav tshem tas li; tsuas yog xav tau kev kuaj xyuas qhov nruj ntawm flange thiab cov xov hlau sensor, txo qis kev ua haujlwm txij nkawm.

5. Cov Kev Txwv (rau kev xaiv siv)

• Tsis rhiab rau cov xov xwm qis-ceev, siab-viscosity: Yuav tsum muaj Reynolds tus lej Re ≥20,000 (gases) lossis ≥5,000 (kua); txwv tsis pub, qhov yuam kev ntsuas yuav nce ntxiv. Tsis haum rau cov roj hnyav, cov kua nplaum, thiab lwm yam.
• Qhov yuav tsum tau ua kom huv nruab nrab: Cov khoom loj loj (qhov loj ntawm cov khoom me me > 5 hli) yuav ua rau cov sensors txhaws lossis ua rau cov khoom kuaj pom puas tsuaj, xav tau cov lim dej rau kev siv.
• Tsis siv tau rau cov kua uas tsis yog Newtonian: Cov kua slurries lossis cov kua uas muaj cov khoom khov kho siab yuav cuam tshuam rau qhov ruaj khov ntawm vortex, ua rau kev ntsuas tsis ua haujlwm.
