ʻO ka pololei o ka heluhelu ʻana o ka flowmeter ka mea i ʻae ʻia o ka hewa pili o ka mika, ʻoiai ʻo ka pololei o ka laulā piha ka mea i ʻae ʻia o ka hewa kuhikuhi o ka mika.
No ka laʻana, ʻo ka piha piha o ka flowmeter he 100m3 / h, ke kahe maoli ʻo 10 m3 / h, inā ʻo ka flowmeter he 1% heluhelu pololei, pono ke ana ʻana o ka mea kani i ka laulā o 9.9-10.1m3 / h [10± (10×0.01)];Inā he 1% ka pololei o ka mīkini kahe, pono ka helu hōʻike mika ma ka laulā o 9-11 m3/h [10± (100×0.01)].
I ka 100 m3 / h ka kahe kahe maoli, inā he 1% ka pololei o ka heluhelu ʻana o ka mika kahe, pono ke ana ʻana o ka mea kani ma ka laulā o 99-101 m3 / h [100± (100×0.01)];Inā he 1% ka pololei o ka mīkini kahe kahe, pono ka helu hōʻike mika ma ka laulā o 99-101 m3/h [10± (100×0.01)].
