摘要： The invention relates to a method of detecting a buildup of silt (32) in a pipe or open channel (14) of a fluid flow network. The pipe or open channel has a system with at least one set of velocity sensors (V1.. V8) to measure flow velocities at predetermined horizontal levels (50... 58). The method includes the steps of computing the flow using the measured flow velocities and cross- sectional areas for each flow layer, and summing the flows to provide a total flow, monitoring the measured flow velocities and storing the flow velocities to detect any ongoing reduction in the flow velocity of at least the lowermost velocity sensor (V1) to provide an indication of a buildup of silt in the pipe or open channel.

摘要： The present invention provides a flow meter (100) for a pipe or open channel (102). The flow meter (100) has a longitudinal member (114) adapted to be inserted into the pipe or open channel (102) but free of any internal wall of pipe or open channel (102). The longitudinal member (114) has a plurality of pairs of acoustic transducers (120, 122) located there around with each pair of acoustic transducers (120, 122) having a transmitting transducer and a receiving transducer. The transmitting transducer sends an acoustic signal to the internal wall of pipe or open channel (102) and the receiving transducer receives the reflected acoustic signal.

摘要： 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.
