Ngaba ubukhulu kunye nezinto ezikwi-insulation layer ziyayichaphazela indlela yokulinganisa xa kufakwa i-clamp-on ultrasonic flowmeter kumbhobho ogqunyiweyo? Ngaba kufuneka unyango olukhethekileyo?

Inempembelelo engathanga ngqo, kodwa imiba ephambili ayilomaleko wokugquma ngokwawo, kodwa zizithuba zomoya phakathi komaleko wokugquma kunye nodonga lwangaphandle lombhobho, kunye nesiphumo sokudibanisa.

• Ukuba umaleko wobushushu (umz., uboya belitye, i-polyurethane) ungena ngokuqinileyo eludongeni lwangaphandle lombhobho kwaye unobukhulu obuyi-≤ 50mm, impembelelo yawo ekuncipheni kwe-ultrasonic incinci (kunye nempazamo edla ngokuba yi-<0.3%).
• Ukuba umaleko wokwambathisa umoya uyaguga kwaye wenze izithuba zomoya zangaphakathi (umoya une-attenuation enamandla kakhulu kumaza e-ultrasonic), okanye ukuba ubukhulu bungaphezulu kwe-100mm, amandla esignali aya kwehla kakhulu, kwaye impazamo yokuchaneka inokwanda iye ngaphezulu kwe-±5%.

Iindlela Zonyango:

1. Indlela ekhethwayo (xa ukususa i-insulation kunokwenzeka): Susa umaleko we-insulation kwindawo yokufakela (indawo ehlutyiweyo kufuneka ibe nkulu kancinci kunesiseko se-sensor), coca amabala omhlwa kunye neoyile eludongeni lwangaphandle lombhobho, uze usebenzise i-agent ekhethekileyo yokudibanisa (endaweni yebhotolo eqhelekileyo) ukuze ufake i-sensor ngokuqinileyo eludongeni lwangaphandle lombhobho.
2. Indlela eyahlukileyo (xa i-insulation ingenakuhluthwa): Khetha i-sensor ehambelana nobushushu obuphezulu kwaye uyidibanise ne-probe ende (ubude be-probe kufuneka bube bude kancinci kunobukhulu bomaleko we-insulation) ukuze uqhagamshelane ngqo nodonga lwangaphandle lombhobho.
