open channel water flow meter

RS485/MODBUS output Wall-mounted Doppler Open Channel Flowmeter DOF6000-W


The DOF6000 series flowmeter consists of Flow calculator and the Ultraflow 6537 sensor.

It is used to measure water velocity, depth, pressure temperature and conductivity of water flowing in rivers, streams, open channels and pipes.


When used with a companion Lanry calculator, flow rate and total flow can also be calculated.


Ultraflow 6537 Instrument is robust, reliable and easy to use. It is completely sealed against water ingress, low maintenance – no calibration, low power – no fussy power arrangements needed. Ultrasonic Doppler Principle in Quadrature Sampling Mode is utilised to measure water velocity. 6537 transmits ultrasonic energy through its epoxy casing into the water. Suspended sediment particles, or small gas bubbles in the water reflect some of the transmitted ultrasonic energy back to 6537 instrument’s ultrasonic receiver. Instrument than processes this received signal and calculates the water velocity. Water depth is also measured with both ultrasonic depth sensor and pressure sensor. This technology enables the Instrument to be completely sealed; potted in a solid block of ‘ultrasonic-transparent’ epoxy and free from any potential leaks that might otherwise occur.


6537 instrument is suitable for use in a wide range of water qualities, from sewage to potable water including sea water. However, it may not be as effective in clean, gas-free water.


6537 instrument measures velocity in both directions. With a companion Lanry Ultraflow software the instrument can be programmed to compute flow rate and total flow in pipes and open channels of known dimensions. Simply mount it on, or near the bottom of the water channel. The Instrument’s low-profile form-factor minimises disturbance to the flow it’s measuring.


The flow calculator can calculate the cross-sectional area of partially filled pipe, open channel stream or river, for stream or river, it can input up to 20 coordinate points describing the river’s shape of cross section. It is suitable for various applications.


Ultraflow 6537 Velocity and Level Transducer is a unique combination of water velocity, depth, pressure, conductivity and temperature instruments integrated with a solid state logger. It is a new generation of intelligent flow measurement systems.


RS485/MODBUS output Wall-mounted Doppler Open Channel Flowmeter DOF6000-W features:

  1. 20 coordinate points to describe the river’s shape of cross section.
  2. One instrument can measure the velocity, depth and conductivity at same time.
  3. Velocity Range : 0.02mm/s to 10m/s bi-directional, accuracy is 1%.
  4. With coordinate correction and pressure compensation function.
