Ukunemba kokufunda kwe-flowmeter kuyinani eliphakeme elivumelekile lephutha elihlobene lemitha, kuyilapho ukunemba kobubanzi obugcwele kuyinani eliphakeme elivumelekile lephutha lokubhekisela lemitha.
Isibonelo, ububanzi obuphelele be-flowmeter buyi-100m3/h, lapho ukugeleza kwangempela kungu-10 m3/h, uma i-flowmeter inembile yokufunda engu-1%, inani lokulinganisa lethuluzi kufanele libe phakathi kuka-9.9-10.1m3/h [10± (10×0.01)]; Uma i-flowmeter inembile ngokuphelele engu-1%, inani lokubonisa imitha kufanele libe phakathi kuka-9-11 m3/h [10± (100×0.01)].
Uma izinga langempela lokugeleza lingu-100 m3/h, uma imitha yokugeleza ingu-1% wokunemba kokufunda, inani lokulinganisa lethuluzi kufanele libe sebangeni elingu-99-101 m3/h [100± (100×0.01)]; Uma imitha yokugeleza ingu-1% wokunemba kwesikali esigcwele, inani lokubonisa imitha kufanele libe sebangeni elingu-99-101 m3/h [10± (100×0.01)].
