Ukunemba kokufunda kwe-flowmeter yinani eliphakeme elivunyelwe lephutha elihlobene lemitha, kuyilapho ukunemba kobubanzi obugcwele kuyinani eliphakeme elivunyelwe lephutha lesithenjwa lemitha.
Isibonelo, uhla olugcwele lwe-flowmeter luyi-100m3/h, lapho ukugeleza kwangempela kungu-10 m3/h, uma i-flowmeter ingu-1% ngokunemba kokufunda, inani lokulinganisa lensimbi kufanele libe ku-9.9-10.1m3 / h [10± (10×0.01)];Uma i-flowmeter ingu-1% ukunemba kwesikali esigcwele, inani lokubonisa imitha kufanele libe kububanzi obungu-9-11 m3/h [10± (100×0.01)].
Uma izinga lokugeleza langempela lingu-100 m3/h, uma imitha yokugeleza ingu-1% ukunemba kokufunda, inani lokulinganisa lensimbi kufanele libe ku-99-101 m3/h [100± (100×0.01)];Uma i-flowmeter ingu-1% ukunemba kwesikali esigcwele, inani lokubonisa imitha kufanele libe kububanzi obungu-99-101 m3/h [10± (100×0.01)].
