Open Channel Flow Meters

Open channel flow meters measure the flow rate of liquids through any flume, weir or other open channel.  This type of instrument is generally used to measure depth, total volume, velocity and, thereby, the flow rate, from a single device. Common applications for open channel flow meters include water management, irrigation and sewage treatment. They tend to be quick and easy to set up, and offer a high level of accuracy.
