Kev xaiv kom raug ntawm cov cuab yeej siv siab feem ntau suav nrog kev txiav txim siab hom, ntau yam, ntau yam, qhov tseeb thiab rhiab heev ntawm qhov ntsuas, qhov ntev ntawm sab nraud, thiab seb yuav tsum muaj kev sib kis ntawm cov chaw taws teeb thiab lwm yam haujlwm, xws li qhia, kaw, hloov kho, thiab tswb.
Lub hauv paus tseem ceeb rau kev xaiv cov cuab yeej siab:
1. Cov kev cai rau kev ntsuas hauv cov txheej txheem tsim khoom, suav nrog ntau yam thiab raug.Nyob rau hauv cov ntaub ntawv ntawm kev ntsuam xyuas zoo li qub (los yog hloov qeeb), qhov siab tshaj plaws ntawm qhov ntsuas qhov siab yuav tsum yog ob feem peb ntawm qhov ntsuas tag nrho ntawm qhov ntsuas siab;nyob rau hauv cov ntaub ntawv ntawm pulsating (fluctuating) siab, qhov siab tshaj plaws tus nqi ntawm qhov ntsuas siab yuav tsum tau xaiv ib nrab ntawm tag nrho cov nqi ntsuas ntawm lub ntsuas siab.
Cov qib raug ntawm cov cuab yeej ntsuas kev ntsuas siab yog 0.05, 0.1, 0.25, 0.4, 1.0, 1.5 thiab 2.5, uas yuav tsum tau xaiv los ntawm qhov tseeb cov cai thiab kev pom ntawm cov txheej txheem tsim khoom.Qhov siab tshaj plaws tso cai yuam kev ntawm qhov ntsuas yog qhov khoom ntawm qhov ntau ntawm lub ntsuas qhov siab thiab qhov feem pua ntawm cov qib raug.Yog tias tus nqi yuam kev tshaj qhov tseeb uas yuav tsum tau ua los ntawm tus txheej txheem, lub ntsuas ntsuas siab nrog qhov raug siab dua yuav tsum tau hloov.
2. Cov khoom ntawm qhov ntsuas nruab nrab, xws li lub xeev (gas, kua), kub, viscosity, corrosiveness, degree ntawm kev sib kis, flammability thiab tawg, thiab lwm yam. xws li oxygen meter, acetylene meter, nrog "tsis muaj roj" kos npe, corrosion- resistant siab gauge rau tshwj xeeb nruab nrab, kub siab ntsuas, diaphragm siab gauge, thiab lwm yam.
3. On-site ib puag ncig tej yam kev mob, xws li ambient kub, corrosion, vibration, av noo, thiab lwm yam. xws li poob siab-pov thawj ntsuas ntsuas rau vibrating ambient tej yam kev mob.
4. Haum rau cov neeg ua haujlwm saib xyuas.Xaiv cov twj paj nruag uas muaj qhov sib txawv (sab nraud qhov ntev) raws li qhov chaw ntawm qhov ntsuas ntsuas thiab cov teeb pom kev zoo
