Contrec 515 Series with OC01 open channel flow computer measures the flow of fluid in an open channel by using a frequency flow meter with a velocity proportional output and an analogue level input. The level input in conjunction with entered dimensional parameters is used to determine the cross-sectional area of the fluid in the channel.
Several regular channels are catered for including Rectangular, Triangular, Trapezoidal, Circular and Half-Round. Flow can be measured in other channel shapes with a Non-linear selection that allows the level input to represent the actual cross-sectional area of the fluid at various levels.
