Thaum ntsuas cov yeeb nkab ntws, cov clamp-on ultrasonic flow meters yog qhov kev xaiv nrov vim tias lawv tsis cuam tshuam thiab yooj yim rau nruab. Txawm li cas los xij, ib qho tseem ceeb ntawm kev siv cov flow meters no feem ntau tsis quav ntsej - qhov xav tau los txheej lawv nrog tus neeg sawv cev txuas. Hauv cov blog no, peb yuav tshawb nrhiav vim li cas clip-on ultrasonic flow meter coatings nrog couplant yog qhov tseem ceeb rau kev ntsuas qhov tseeb thiab txhim khu kev qha.
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab txog seb lub clamp-on ultrasonic flowmeter ua haujlwm li cas. Cov khoom siv no siv cov nthwv dej ultrasonic los ntsuas qhov ntws ntawm cov kua hauv cov kav dej. Lub sensor ntawm lub flow meter raug clamped rau sab nraud ntawm cov kav dej, thiab lub teeb liab ultrasonic raug xa mus los ntawm phab ntsa yeeb nkab mus rau hauv cov kua ntws. Lub sensor ntawm sab tod ntawm cov kav dej ces txais lub teeb liab thiab xam tus nqi ntws raws li lub sijhawm nws siv rau lub teeb liab mus ncig ntawm cov sensors.
Lub sijhawm no, lub luag haujlwm ntawm tus neeg sawv cev txuas los ua si. Ua ntej clamping lub sensor rau ntawm lub yeeb nkab, tus neeg sawv cev txuas (feem ntau yog gel lossis paste) raug siv rau ntawm qhov chaw ntawm lub sensor. Cov couplant no ua haujlwm ua ib qho nruab nrab, txhim kho kev xa cov teeb liab ultrasonic ntawm lub transducer thiab phab ntsa raj. Yog tsis muaj couplant, qhov sib txawv cua yuav tsim ntawm lub sensor thiab lub yeeb nkab, uas tuaj yeem ua rau poob teeb liab thiab kev ntsuas tsis raug.
Tsis tas li ntawd xwb, couplant pab tshem tawm txhua qhov tsis sib xws lossis qhov tsis zoo ntawm phab ntsa raj uas yuav cuam tshuam rau kev xa cov teeb liab ultrasonic. Los ntawm kev muab qhov sib txuas du thiab sib xws ntawm lub transducer thiab cov yeeb nkab, lub couplant ua kom ntseeg tau tias cov nthwv dej ultrasound tuaj yeem hla dhau phab ntsa yeeb nkab thiab mus rau hauv cov kua dej ntws yam tsis muaj kev cuam tshuam.
Lwm qhov laj thawj tseem ceeb uas ua rau cov clamp-on ultrasonic flowmeters raug coated nrog couplant yog los txhim kho qhov kev ua tau zoo thiab lub neej ua haujlwm ntawm lub flowmeter. Tus neeg sawv cev coupling ua haujlwm ua ib qho kev tiv thaiv, tiv thaiv lub sensor los ntawm cov yam ntxwv sab nraud xws li dej noo, hmoov av, thiab xeb. Qhov no tseem ceeb heev rau hauv cov chaw ua haujlwm, qhov twg cov flowmeters yuav raug rau cov xwm txheej hnyav uas yuav ua rau lawv cov kev ua tau zoo poob qis dhau sijhawm.
Ntxiv rau cov yam ntxwv ntawm kev siv tshuab, daim ntawv thov ntawm couplant kuj ua rau cov txheej txheem teeb tsa ntawm clamp-on ultrasonic flow meters yooj yim dua. Los ntawm kev ua kom muaj kev sib txuas zoo thiab ruaj ntseg ntawm lub sensor thiab yeeb nkab, couplant txo qhov kev pheej hmoo ntawm kev plam lossis tsis sib haum thaum lub sijhawm teeb tsa, txuag tus neeg teb xov tooj lub sijhawm thiab kev siv zog.
Hauv kev xaus, kev txheej txheem ntawm lub clamp-on ultrasonic flowmeter nrog tus neeg sawv cev coupling yog ib kauj ruam tseem ceeb hauv kev ua kom muaj kev ntsuas ntws raug, txhim khu kev qha thiab ruaj khov. Txij li kev txhim kho kev xa cov teeb liab ultrasonic mus rau kev muab kev tiv thaiv rau cov sensors, couplant ua lub luag haujlwm tseem ceeb hauv kev ua tau zoo ntawm cov ntsuas ntws no. Yog li ntawd, cov neeg teb xov tooj thiab cov kws kho tshuab yuav tsum paub txog qhov tseem ceeb ntawm kev siv couplant thiab ua raws li cov txheej txheem thov kom raug kom ua tau zoo tshaj plaws ntawm clamp-on ultrasonic flow meters hauv ntau yam kev lag luam thiab kev lag luam.
