open channel water flow meter

DOF6000-W Wall-mounted Open Channel Ultrasonic Flow Meter

The DOF6000 series flowmeter consists of Flow calculator and the Ultraflow QSD 6537 Sensor.
The Ultraflow QSD 6537 Sensor is used to measure water velocity, depth, and conductivity of water flowing in rivers, streams, open channels and pipes. When used with a companion Lanry DOF6000 Calculator, flow rate and total flow can also be calculated.The flow calculator can calculate the cross-sectional area of partially filled pipe, open channel stream or river, for stream or river, with up to 20 coordinate points describing the river’s shape of cross section. It is suitable for various applications.

 Water depth is measured with two methods. An ultrasonic depth sensor measures water depth using the ultrasonic principle from a top mounted sensor on the instrument. Depth is also measured using the pressure principle from a bottom mounted sensor in the instrument. These two sensors provide flexibility in depth measurement. Some applications, for example measuring from the side of a pipe, better suits a pressure principle, while other applications in clear open channels better suit an ultrasonic principle.
The open channel flowmeter monitoring system is suitable for the flow measurement of rectangular, trapezoidal open channels and culverts such as reservoirs, rivers, water conservancy projects, urban water supply, sewage treatment, farmland irrigation, and water resources. It has been widely used in recent years.
