Principle of Measurement

The Doppler ultrasonic flow meter is designed to measure volumetric flow of liquid within closed conduit, the pipe line must be filled full of liquids, there must be Ta certain amount ofT air bubbles or suspended solids in liquid.

Transducers are clamp-on or hot-tapped probe types, user don’t need to shut down the pipe flow when install the clamp-on transducers.

The flow meter operates by transmitting an ultrasonic sound from its transmitting transducer, the sound will be reflected by useful sonic reflectors suspended within the liquid and recorded by the receiving transducer. If the sonic reflectors are moving within the sound transmission path, sound waves will be reflected at a frequency shifted (Doppler frequency) from the transmitted frequency. The shift in frequency will be directly related to the speed of the moving particle or bubble. This shift in frequency is interpreted by the instrume

nt and converted to various user defined measuring units.

There must be some particles large enough to cause longitudinal reflection – particles larger than 100 micron.

When install the transducers, the installation location must have enough straight pipe length upstream and downstream. Commonly, the upstream needs 10D and downstream needs 5D straight pipe length, where D is pipe diameter.

Series DMDFB Doppler ultrasonic flow meter is designed to measure volumetric flow of liquid within closed conduit, the pipe line must be filled full of liquids, there must be Ta certain amount ofT air bubbles or suspended solids in liquid.

The Doppler ultrasonic flow meter can display flow velocity, flow rate and flow totalizer, etc, and is configured with 4-20mA, Totalizer Pulse and Relay Alarm output.

Features of the Doppler ultrasonic flow meter:

1. The system can be field configured to pipe sizes ranging from 15 to 4000mm.

2.For dirty liquids, a certain amount of air bubbles or suspended solids contain

3. Excellent low flow rate measurement ability, low to 0.05m/s

4. A wide range of flow measurement, high flow rate can reach 12m/s

5.Automatically signal gain adjustment

6.Do not need to shut down the pipe flow when installing the transducers.

7. User-friendly configurations

8.4-20mA, totalizer pulse and relay alarm output

9. Accuracy: 2.0% Calibrated span

Applications of the Doppler flowmeters:

1.Raw sewage

2.Return activated sludge

3.Waste activated sludge

4.Ground water

5. Pulp and paper slurries

6. Chemical slurries

7. Drainage

8.Mining recirculation

9. Animal renderings
