Open Channel Flow Meters
Open channel flow measurement solutions. We offer a range of effective technologies for the measurement of water and waste water flows within open channels including flumes, weirs, drains or partially filled pipes.
Our ultrasonic level and velocity based systems offer good accuracy at low cost and are used in conjunction with a primary flow installations such as flumes, weirs and bowls. Alternatively it is possible to install flow sensors within any channel, pipe or stream itself. These are known as area velocity flowmeters and measure level and velocity together to compute accurate flow rate and offer logging and telemetry options. Eastech Cartridge Flow Meters are quite unique and are especially good at measuring low flows in partially full pipe applications, as well as being able to cope with full pipe and flooded chamber flow measurement.
