Get PriceSluice gate flow metering is often used to measure flow rate in open channels Sluice gates are also often used to modulate flow The sluice gate flow rate measurement is based on the Bernoulli Equation and can be expressed as 1/2 ρ v 1 2 ρ g h 1 = 1/2 ρ v 2 2 ρ g h 2 1 where h = elevation height m ρ = density kg/m 3 v = flow velocity m/s
