Kev nyeem ntawv qhov tseeb ntawm lub flowmeter yog qhov siab tshaj plaws tso cai tus nqi ntawm qhov txheeb ze qhov yuam kev ntawm qhov ntsuas, thaum qhov ntsuas qhov tseeb tag nrho yog qhov siab tshaj plaws tso cai tus nqi ntawm qhov kev siv yuam kev ntawm qhov ntsuas.
Piv txwv li, tag nrho cov flowmeter yog 100m3 / h, thaum qhov tseeb ntws yog 10 m3 / h, yog hais tias lub flowmeter yog 1% kev nyeem ntawv, qhov ntsuas ntsuas tus nqi yuav tsum nyob rau hauv thaj tsam ntawm 9.9-10.1 m3 / h [ 10 ± (10 × 0.01)].
Yog hais tias lub flowmeter yog 1% tag nrho qhov tseeb, qhov ntsuas ntsuas qhov ntsuas yuav tsum nyob hauv thaj tsam ntawm 9-11 m3 / h [10 ± (100 × 0.01)].
Thaum qhov tseeb ntws yog 100 m3 / h, yog tias lub flowmeter yog 1% kev nyeem ntawv, qhov ntsuas tus nqi ntawm cov ntsuas yuav tsum nyob rau hauv thaj tsam ntawm 99-101 m3 / h [100 ± (100 × 0.01)];Yog hais tias lub flowmeter yog 1% tag nrho qhov tseeb, qhov ntsuas ntsuas qhov ntsuas yuav tsum nyob hauv thaj tsam ntawm 99-101 m3 / h [10 ± (100 × 0.01)].
