A system for measuring or monitoring the quality of a liquid medium, has first and second sample-takeoff points in the liquid medium and a hydraulic circuit in which the samples taken off from said first and second sample-takeoff points circulate. The hydraulic circuit is mounted between the two sample-takeoff points and comprises two centrifugal impeller pumps, a measuring chamber situated between the two pumps, and a purge device mounted at a high point on the hydraulic circuit between one of the pumps and the measuring chamber. The whole of the hydraulic circuit is preferably totally immersed in the liquid medium.
