Rotameter correction factor
WebSep 1, 1996 · A very good agreement between theoretical calculation and calibration results was obtain for water flow at 88°C. In this case the kinematic viscosity ratio was v 15 /v 88 = 3.46 and the density correction factor was F dens = 1.019 and the viscosity correction factor varied from F visc = 1.095 at 100 l/hr to F visc = 1.93 at 10 l/hr. WebUsually, flow rates are measured at ambient temperature and pressure. If it is necessary to compare flow rates taken under different temperature and/or pressure conditions, a correction factor relative to a set standard temperature and pressure should be applied: F ref = F amb [P amb /P ref] [T ref /T amb] Where: F ref = flow corrected to ...
