Ukuchaneka kokufunda kwe-flowmeter lixabiso eliphezulu elivumelekileyo lempazamo ehambelanayo yemitha, ngelixa uluhlu olupheleleyo luyixabiso eliphezulu elivumelekileyo lempazamo yereferensi yemitha.
Ngokomzekelo, uluhlu olupheleleyo lwe-flowmeter yi-100m3 / h, xa ukuhamba kwangempela ku-10 m3 / h, ukuba i-flowmeter i-1% yokuchaneka kokufunda, ixabiso lokulinganisa isixhobo kufuneka libe kuluhlu lwe-9.9-10.1m3 / h [10± (10×0.01)];Ukuba i-flowmeter yi-1% yokuchaneka kwesikali esipheleleyo, ixabiso lokubonisa imitha kufuneka libe kuluhlu lwe-9-11 m3 / h [10± (100×0.01)].
Xa izinga lokuhamba langempela liyi-100 m3 / h, ukuba imitha yokuhamba i-1% ngokuchanekileyo kokufunda, ixabiso lokulinganisa isixhobo kufuneka libe kuluhlu lwe-99-101 m3 / h [100 ± (100 × 0.01)];Ukuba i-flowmeter yi-1% yokuchaneka kwesikali esipheleleyo, ixabiso lokubonisa imitha kufuneka libe kuluhlu lwe-99-101 m3 / h [10± (100 × 0.01)].
