Ukunemba kokufunda kwe-flowmeter kumelela inani eliphezulu elivumelekile lephutha elihlobene nethuluzi, kuyilapho ukunemba okugcwele kuyinani eliphezulu elivumelekile lephutha elicashuniwe lethuluzi.
Isibonelo, uma isikali esiphelele se-flowmeter singu-100 m³/h, lapho izinga langempela lokugeleza lingu-10 m³/h:
- Uma i-flowmeter inokunemba kokufunda okungu-1%, inani elilinganisiwe lethuluzi kufanele libe phakathi kuka-9.9 - 10.1 m³/h [10 ± (10 × 0.01)].
- Uma i-flowmeter inokunemba okugcwele okungu-1%, inani elibonisiwe lethuluzi kufanele libe ngaphakathi kwebanga elingu-9 - 11 m³/h [10 ± (100 × 0.01)].
Uma izinga langempela lokugeleza lingu-100 m³/h:
- Uma i-flowmeter inokunemba kokufunda okungu-1%, inani elilinganisiwe lethuluzi kufanele libe ngaphakathi kwebanga elingu-99 - 101 m³/h [100 ± (100 × 0.01)].
- Uma i-flowmeter inokunemba okugcwele okungu-1%, inani elibonisiwe lethuluzi kufanele libe ngaphakathi kobubanzi obungu-99 - 101 m³/h [100 ± (100 × 0.01)].
