Yuav ua li cas thiaj li ntawv pov thawj ua tau zoo colrelate nrog ntev - sij hawm kev cia siab?
ISO / iEC 17025 calibration lab ua haujlwm ATEX / IECEX ntawv pov thawj rau thaj chaw muaj kev phom sij qhia cov neeg tsim khoom siv cov neeg siv khoom lag luam zoo nkauj thiab nqis peev pab nruj. Conversely, Generic CE khij thiab cov ntawv pov thawj kev nyab xeeb yog cov ceg txheem mos uas tsis sib txawv. Thov cov ntawv pov thawj pov thawj tiag tiag - tsis yog hais txog kev ua raws li. Cov neeg tsim khoom nkag siab hauv lawv cov ntawv pov thawj muab cov ntaub ntawv ntxaws ntxaws yooj yim; Cov neeg tsis txaus ntseeg feem ntau tuav cov kev pom zoo lossis tsis tiav kev pom zoo.
Kuv puas yuav tsum xaiv multi - txoj kev lossis ib -}} lub sij hawm meters?
Ntau - txoj kev ({3+ acoustic paths) rau kev saib xyuas menyuam) rau tsawg dua qhov zoo tshaj cov yeeb nkab ncaj nraim khiav. The 30-50% cost premium over single-path pays off through superior accuracy (±0.5% vs ±1-2%), flow profile compensation, and diagnostic capabilities. Ib Leeg - txoj hauv kev ua tiav kev ua tiav zoo hauv cov dej huv nrog cov dej khov ({} diam hlau sab nraud dej). Rau feem ntau cov txheej txheem tswj cov txheej txheem, kom zoo rau ib qho - txoj kab meters xa cov nqi qis. Qhov tseem ceeb tshaj tawm tau: kev teeb tsa zoo. Yog tias koj tsis tuaj yeem lav cov piping zoo tshaj plaws geometry, ntau txoj kev architecture muab kev pov hwm tawm tsam cov kev cuam tshuam kev ntws. Baker Hughes, Krohne, thiab Emerson Daniel series muab cov kev xaiv ntau ntau txoj kev.
