Products Details

Series DF6100-EH Doppler Handheld Ultrasonic Flow Meter is designed to measure volumetric flow of within closed conduit, the pipe line must be full of liquids, and there must be a certain amount of air bubbles or suspended solids in liquid. The Doppler ultrasonic flow meter can display flow rate and flow totalizer, etc., and is configured with 4-20mA, OCT outputs.
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 a certain amount of 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 instrument 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.
Applications:raw sewage / domestic water/waste water/chemical indystry/drainage/sanitary water/dirty liquids/ground water/slurry/mining plants/activated sludge/paper slurry and so on.
Measure : The flow of  liquids (Total flow & flow totalizer )

NOTES FOR APPLICATION
‹ When installing transducers, it need enough straight pipe;
‹ When straight pipe is not enough, by setting menu SERVICE, the flowmeter will still get high accuracy, and obtain a more accurate reading. more details, please see 4.3.16 SERVICE mode;
‹ The measured liquid must contain a certain amount of air bubbles or suspended solids. When the liquid contains air bubbles too much or too big, the bubbles occupy a certain volume, and then lead
to larger flowmeter reading. In this case, it needs to recalibrate the flowmeter.
‹ When installing clamp-on transducers, the pipe material should have a good acoustical conductivity;
‹ When the transducer need be installed underground, recommend the insertion type.
It is suitable for pipe sizes ranging from 40 to 4000mmFor dirty liquids, a certain amount of air bubbles or suspended solids shall be containedExcellent low flow rate measurement ability, low to 0.05m/sA wide range of flow measurement, high flow rate can reach 12m/sHigh-temperature transducer is suitable to liquids of -35℃ ~ 200℃Do not need to shut down the pipe flow when installing the transducers
