ABSTRACT:
A flow indicator has a pivoting flap fitted in ducting of a hydraulic installation which transports contaminated liquids. To permit the purge of a reservoir, the flap has an opening for air returning through the ducting. The opening prevents overpressure or vacuum in a circuit. The invention applies specifically to purge and vent circuits for nuclear power installations.
