Ultrasonic Flow Measurement Box

Product Manual

This box-type ultrasonic open channel flowmeter adopts the velocity-area method. Flow velocity is measured by the ultrasonic time-difference method with multiple pairs of transducers for layered velocity detection.

Water level is measured simultaneously via three approaches: electronic water gauge, ultrasonic level meter and ultrasonic transducers. The main controller compares the three groups of level data and selects the most reliable value for flow calculation.

n Real-time monitoring of water level and layered flow velocity; high-precision flow calculation.

n Real-time monitoring of water level and layered flow velocity; high-precision flow calculation.

n Excellent anti-sediment performance, high accuracy and wide flow velocity range.

n Compatible with solar power supply; can work independently on channels and upload data of water level, flow velocity and flow rate.
