Abstract

Method of rinsing a device for circulating a liquid between a storage tank (1) and a sampling head (2) from a feed pipe (3) to which is connected a propulsing air pipe (12). The rinsing operation consists in injecting a rinsing fluid (21, 22, 23, 24, 25) into the feed pipe (3) or into the propulsing air pipe (12), the latter being supplied with gas during rinsing of the device. <IMAGE>
