Ehe. Ma flowmeter emagetsi emagetsi emagetsi ega anowanzo yera kumhanya kwekuyerera pakati pepombi uye obva aishandura kuita avhareji yekumhanya kwekuyerera muchikamu chepombi achishandisa "average velocity coefficient." Iyi coefficient yakavakirwa pakufungidzira kwe "kuyerera kwakanyatsogadzirwa" (apo kumhanya kunotevera kugoverwa kwe logarithmic). Zvisinei, mumapaipi ane dhayamita hombe, kana mwero wekuyerera wakaderera (mumamiriro e laminar kana low-turbulence ane nhamba yaReynolds < 2300), kugoverwa kwekukurumidza kuri pedyo nechimiro cheparabolic. Nekuda kweizvozvo, kukanganisa kwekushandura kwemamita enzira imwe chete (kubva pakukurumidza kwepakati kusvika paaverage velocity) kunowedzera kubva pa ±1% kusvika kupfuura ±3%.
Kusiyana neizvi, ma "flowmeters" ane nzira dzakawanda (semuenzaniso, "4-path" kana "8-path") anoyera "flow velocity" panzvimbo dzakasiyana dze "radial" uye anoverenga "weighted avhareji", iyo inogona kunyatsogadzirazve "cross-sectional velocity distribution". Kunyangwe mumamiriro ekuyerera kwakaderera, kururama kwawo kunogona kuramba kwakasimba mukati me ± 0.5%.
Saka, pakuyera nzira dzemagetsi dzinomhanya zvishoma (senge muma network emvura kana mapaipi makuru etsvina) mumapaipi ane dhayamita hombe, kunaka kwema flowmeters ane nzira dzakawanda kunowedzera kuoneka sezvo mwero wekuyerera kwemvura uchiderera.
