The equipment enables to carry out measurements of flow rate using a Venturi meter, a calibrated orifice and a variable area flow meter connected in series. A flow control valve enables to vary the flow rate across the circuit. Each element is equipped with two pressure tapping points connected to a differential pressure gauge of six tubes.
