The invention provides an undershot sluice gate (17) to control flow of liquid through an open channel (10). The gate (17) includes a gate leaf (18) adapted to be raised and lowered by a control means (22) to allow flow of liquid along open channel (10). Gate leaf (18) has at least a pair of opposing liquid level sensors (44, 46) on, or in, gate leaf (18) to provide measurement of liquid level upstream and downstream of gate leaf (18). The sensors (44, 46) are located at a predetermined distance from the lowermost edge of gate leaf (18) to allow said measurements without disturbance from the fluid flow profile resulting from movement of liquid beneath the lowermost edge of gate leaf (18).
