DOF6000-W Wall-mounted Doppler Open Channel 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.

The 6537 instrument comprises a 4-electrode conductivity instrument (EC) for measuring water quality with four electrodes exposed to water at the top of the instrument.Continuous measurement of water quality can record this parameter as well as speed and depth to better analyze the nature of water in open channels and pipes.




  1. One instrument can measure the velocity, depth and conductivity simultaneously.
  2. Velocity Range: 0.02mm/s to 12m/s bi-directional, accuracy is 1%.
  3. Depth is measured by both the pressure sensor and ultrasonic level sensor principles.
  4. With barometric pressure compensation function.
  5. 20 coordinate points to describe cross section of the river’s shape.
  6. IP68 Epoxy-sealed body design, designed for under water installation.
  7. RS485/MODBUS output, can connect to computer directly.
  8. Measure velocity in both forward flow and back flow.
