We offer systems and sensors to monitor and record water flow through open channels. We can help you to design a complete monitoring and control system, or simply sell you the parts and sensors that you require. We have been working in the flow monitoring business for many years and have the experience and knowledge to help you find the meters, devices and systems to meet your project needs.
Open Channel Flow
Open channel flow is generally any flow through a ditch or conduit that is not pressurized. We offer other sensors and meters for a pressurized system, or full pipes. It is very common to use flumes or weirs in open channel ditches.
We offer water level sensors, which can be configured to “calculate” flow in ditches or non-pressurized conduits. This option is often called a rated section or rated flow. This is only recommended if an estimated flow rate will be acceptable. This procedure requires flow to be manually measured using a device like the flow probe shown further down on this page. Once flow has been measured at different depths in the channel you can build a rating table that uses depth to estimate the flow rate. We can be hired to come to your location and create a flow rating table, this often takes multiple site visits. One consideration to this option is that vegetation and silting of the channel can affect this calculation throughout the season.
