The invention provides a control gate (10) adapted to be installed across a channel (12) for liquids. Control gate (10) has a barrier member (22) that is pivotally mounted at or adjacent the base (20) of flow channel (12) and at least one side member (26) attached to barrier member (22). A drive means (34) co-operates with the at least one side member (26) or central member to allow raising and lowering of barrier member (22) to regulate flow of liquid through control gate (10). Also described is a method of measuring flow rate through a control gate.
L'invention concerne une vanne (10) de régulation conçue pour être installée transversalement dans un conduit (12) pour liquides. Cette vanne (10) de régulation comprend un élément (22) barrière monté de manière pivotante sur le fond (20) ou à proximité immédiate du fond (20) du conduit d'écoulement, et au moins un élément (26) latéral connecté avec cet élément (22) barrière. Des moyens (34) de commande coopèrent avec l'élément (26) latéral ou les éléments latéraux, ou avec un élément central de manière à permettre l'élévation et l'abaissement de l'élément (22) barrière afin de réguler l'écoulement de liquide à travers la vanne (10) de régulation. L'invention concerne également un procédé permettant de mesurer le débit à travers la vanne de régulation.
