The KOBOLD flow meter model RCD is used for measuring and monitoring liquid and gas flows. The device works on the well-known principle of the Venturi nozzle. A small pressure difference proportional to the flow is produced by the flowing medium at an orifice constriction (nozzle) in the device housing.
