Qhov nyeem tau qhov tseeb ntawm lub flowmeter yog qhov siab tshaj plaws uas tso cai rau ntawm qhov yuam kev ntawm lub cuab yeej, thaum qhov tseeb ntawm qhov ntsuas tag nrho yog qhov siab tshaj plaws uas tso cai rau ntawm qhov yuam kev siv ntawm lub cuab yeej.
Piv txwv li, tag nrho cov flowmeter yog 100m3 / h, thaum qhov tseeb ntws yog 10 m3 / h, yog tias lub flowmeter yog 1% nyeem qhov tseeb, tus nqi ntsuas ntawm lub 'meter' yuav tsum nyob rau hauv qhov ntau ntawm 9.9-10.1 m3 / h [10 ± (10 × 0.01)].
Yog tias lub ntsuas dej ntws yog 1% qhov tseeb tag nrho, tus nqi ntawm cov cuab yeej tso saib yuav tsum nyob rau hauv qhov ntau ntawm 9-11 m3 / h [10 ± (100 × 0.01)].
Thaum qhov ntws tiag tiag yog 100 m3 / h, yog tias lub ntsuas dej yog 1% nyeem qhov tseeb, tus nqi ntsuas ntawm lub cuab yeej yuav tsum nyob rau hauv qhov ntau ntawm 99-101 m3 / h [100 ± (100 × 0.01)]; Yog tias lub ntsuas dej yog 1% tag nrho qhov tseeb, tus nqi tso saib ntawm lub cuab yeej yuav tsum nyob rau hauv qhov ntau ntawm 99-101 m3 / h [10 ± (100 × 0.01)].
Cov ntsuas ntws ntawm Lanry Instruments yog raws li hauv qab no
Cov yeeb nkab puv ib nrab & qhib channel ultrasonic flow meter TF1100 series, qhov tseeb yog 1% nyeem ntawv.
