Cov clamp-on ultrasonic flowmeters puas tuaj yeem ntsuas cov kua viscous?

Cov ntsuas dej ultrasonic clamp-on tuaj yeem ntsuas cov kua dej uas muaj viscous, tab sis lawv qhov kev haum thiab qhov tseeb nyob ntawm qib viscosity thiab cov xwm txheej ntws tshwj xeeb. Nov yog cov lus qhia ntxaws ntxaws:

Thaum Twg Cov Kua Uas Muaj Viscous Tuaj Yeem Ntsuas Tau

• Qhov nruab nrab viscosity: Cov kua uas muaj viscosity nruab nrab (piv txwv li, roj cav, roj nplua nyeem me me, lossis cov kua txiv hmab txiv ntoo dilute) feem ntau tuaj yeem ntsuas tau zoo, yog tias qhov ntws yog turbulent lossis ruaj khov laminar ntws. Hauv cov xwm txheej zoo li no, lub teeb liab ultrasonic tseem tuaj yeem kis mus rau hauv cov kua, thiab qhov ceev ntawm cov dej ntws tseem sib xws txaus rau kev suav lej raug.
• Cov xwm txheej ntawm cov yeeb nkab kom zoo: Yog tias cov yeeb nkab du, tsis muaj qhov qias neeg heev, thiab ua los ntawm cov khoom siv uas tso cai rau cov nthwv dej ultrasonic nkag mus (piv txwv li, hlau lossis yas homogeneous), lub 'meter' tuaj yeem ua haujlwm tau zoo txawm tias muaj cov kua nplaum.

Cov Teeb Meem Nrog High Viscosity

• viscosity siab heev: Rau cov kua uas viscosity heev (piv txwv li, cov roj hnyav, cov nplaum tuab, lossis cov polymers molten), qhov tseeb ntawm kev ntsuas yuav poob qis heev. Cov kua no feem ntau qhia txog cov qauv ntws tsis sib xws (piv txwv li, ntws ntsaws, qhov twg cov kua txav mus ua cov khoom khov kho) lossis qeeb qeeb, uas tuaj yeem cuam tshuam qhov sib txawv ntawm lub sijhawm mus ncig ntawm lub teeb liab ultrasonic - lub hauv paus ntsiab lus tseem ceeb rau kev xam ntws.
• Kev tsis ruaj khov ntawm cov dej ntws: Kev viscosity siab tuaj yeem ua rau cov qauv ntws tsis sib xws, xws li kev txav mus los lossis kev nyob tsis ruaj khov ze ntawm phab ntsa yeeb nkab, ua rau kev nyeem ntawv tsis sib xws.

Cov Kev Xav Txog Kev Ua Tau

• Kev Kho Kom Zoo: Rau cov kua nplaum nplaum, kev kho kom zoo lossis kev lees paub nrog cov kua tshwj xeeb yog qhov pom zoo kom suav nrog cov teebmeem ntsig txog viscosity rau tus cwj pwm ntws.
• Kev tso qhov chaw ntawm lub sensor: Kev xyuas kom meej tias cov sensors tau teeb tsa rau hauv ib ntu yeeb nkab ncaj (nrog qhov ntev txaus ntawm sab saud/sab hauv qab) pab kom ruaj khov qhov profile ntws, txhim kho qhov tseeb.
• Cov lus qhia ntawm lub 'meter': Qee cov clamp-on ultrasonic flowmeters tau tsim los nrog cov algorithms siab heev los tswj cov viscosity ntau dua, yog li xaiv cov qauv zoo rau cov ntawv thov zoo li no yog qhov zoo.
