摘要:
The invention discloses a method of predicting the fluid level at a predetermined location in a fluid flow network (10) having at least one regulator (16, 18) to control the flow of fluid along fluid flow network (10). The method includes the steps of collecting data based on timed measurements of fluid levels upstream (24, 28) of at least one regulator (16, 18), fluid levels downstream (26, 29) of at least one regulator (16, 18) and the opening position (30, 32) of at least one regulator (16, 18), and using data analysis (40) to provide a model based on the data whereby the model will provide prediction of fluid level at the predetermined location based on timed measurements of fluid levels upstream (24, 28) of at least one regulator (16, 18) and the opening position (30, 32) of at least one regulator (16, 18).

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.

The invention discloses a loss detection system to determine and monitor containment losses for open channel networks (10). The system includes at least first and second flow regulators (26, 28) to allow flow of liquid into and out of at least one pool (10) respectively. First and second flow sensors co-operate with respective flow regulators (26, 28) and a computational means communicates with flow regulators (26, 28) and the flow sensors to control operation of flow regulators (26, 28). The computational means determines the containment losses by calculating the measured flow into at least one pool (10) through at least first flow regulator (26) and subtracting the measured flow out of at least one pool (10) through at least second regulator (28).
