Continuous measurement for river or open channel flow
WKF-RFM River flow meter has built-in flow velocity sensor and liquid level sensor, can continuously measure the water level, surface velocity of water without contact.
This method is not affected by water plants or sediment, which reduces maintenance costs and increases stability.
Principle
Through radar water level and surface velocity detection, water level information and average flow velocity information are collected in real time at the point to be measured, and the production flow information of rivers and open channels is combined with signal processing of the topography. This method adopts non-contact detection.
For regular channel sections, conventional mathematical formulas are used to calculate the flow results. For irregular river sections, the discharge results are obtained by using the tracing method and calculus calculation. Not affected by factors such as temperature, rainfall, muddy water, sludge, aquatic plants, etc., has high detection accuracy and strong interference resistance.
Computer software is standard for equipment configuration. Or order a Bluetooth model, you can store and download the measurement data, and set it directly on your mobile phone.
- Radar flow meters detect through radio waves without contact with water, avoiding problems that may be encountered by traditional mechanical or contact measuring equipment, such as clogging, wear, etc.
- The radar flow sensor is suitable for various types of channel flow measurement, including rectangular canals, trapezoid canals, triangular canals, U-shaped canals, etc. At the same time, special channel settings are provided for irregular channels and rivers, and the area of irregular sections can be completely calculated by inputting coordinate information of several points.
- This open channel flow instrument is of small size, has a few wire sequences, is simple in wiring, easy to install, and has less maintenance workload.
- The shell is made of aluminum alloy material with a protection level of IP68. The average working life of the equipment is 8 to 15 years.
- This flow measurement device adopts a low-power design, working voltage range 7V to 28V DC, and a small working current, making it suitable for long-term work in the wild or unattended environments.
Radar open-channel flow meter suitable for measuring flow in rectangular and trapezoidal open channels and culverts in reservoirs, rivers, water conservancy projects, urban water supply systems, sewage treatment facilities, farmland irrigation, water management, and water resource management.
