MJ – FSense uses radar sensor technology to measure the water level and velocity of the open channel. With the real-time collection of water level information and average velocity, the data is calculated with the open channel topography information to generate flow information.
MJ – FSense uses non-contact detection, which reading is not affected by temperature, rainfall, muddy water, sludge and aquatic plant. With its high detection accuracy and strong anti-interference characteristic, it can be adapted to various type of open channel in different environments.
With build-in wind speed and wind direction meter, the water surface velocity affected by the wind is automatically compensated.
Applications include open channel monitoring, waste discharge monitoring, pollution control monitoring and more!

Radar measures flow by determining the velocities on the water surface. The surface velocities are determined by detecting Radar signals reflected from surface waves. The reflections are evaluated using the known Doppler principle. Utilising additional level measurement and by taking the known channel shape into account it is possible to accurately calculate the flow rate.
Based on the pulsed radar principle, the measurement is done in pulses called the pulse procedure, where a transmitter sends out a short microwave pulse, followed by a period where the receiver picks up the signals reflected by the water. The received signal is then processed by the internal processor. The time travelled by the pulse corresponds with the distance travelled to and from the surface of the water. The principle makes it possible for a simple yet accurate water level measurement that can be deployed to many applications due to its non-contact technology.
