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