The ORAKEL Flume or Weir Flow Meter is an Open Channel Flow Meter with a Non-Contact Flow Sensor that uses radar technology and a velocity ‘x’ area calculation to provide a cost-effective flow measurement.
The ORAKEL Open Channel Flow Meter, also called as flume or weir flow meter, is a non-contact flow sensor that is designed applications where liquid contact is prohibited or undesirable. The ORAKEL Open Channel flow meter measures water flow rate, level, and total volume of water flowing through open channels. This includes flumes, weirs, irrigation channels, and partially filled pipes for industrial discharge or sewer flow.
In open-discharge water applications where installing a flume or weir is not possible, you might want to consider our submersible area-velocity open-channel flow meter.
The ORAKEL non-contact sensor can be combined with a level transducer and controller in order to provide a complete flow measurement system. It has an extremely low power consumption, making it suitable for a broad range of wastewater monitoring applications and use in remote installations, where mains power is unavailable.
