Abstract
The invention relates to a drainage circuit (4) for a flow of a liquid (5), the circuit being fitted with a monitoring appliance (13) for monitoring an excess flow rate of the liquid (5). The monitoring appliance (13) comprises a monitoring duct (14) interposed between an upstream duct (7) for collecting the liquid (5) and a downstream duct (9) for discharging the liquid (5). The monitoring duct (14) has retaining means (15) for retaining part of the liquid (5) inside a chamber (16) arranged to receive a spillway (22) of the captured liquid (19) in a reserve (20) fitted with indicator means (23) with a visual scale for providing warning information relating to the quantity of liquid (24) contained in the reserve (20).
