Doppler velocimeter is a velocity and flow detection instrument applied to rivers, open channels and pipelines. Using ultrasonic detection technology, it has the advantages of high measurement accuracy, good stability, little influence by environmental factors, no rotating parts, low maintenance frequency and high working reliability, and is the first choice for portable velocity and flow measurement.
1. Product Introduction
Acoustic Doppler velocimeter is a flow velocity and flow rate detection instrument applied to rivers, open channels and pipelines. It adopts ultrasonic detection technology, with high measurement accuracy, good stability, less affected by environmental factors, no rotating parts, low maintenance frequency, and high working reliability. It is the preferred product for portable flow velocity and flow rate measurement.
Principle: In the field of acoustics, when there is a relative motion between the sound source and the receiving body (i.e. the probe and the reflector), the frequency of the echo will change, this frequency change is called frequency shift, i.e. the Doppler effect. The sound wave frequency increases when it moves towards the observer and decreases when it moves away from the observer. The Doppler flow meter calculates the flow rate by calculating the frequency change.
2. Application fields
Sponge city, river chief system management, inland river monitoring, natural rivers, open channels, pipelines, aquaculture and other scenarios.
Three, main features
Measuring the flow, velocity, and water level of pipes, channels, and natural rivers.
Single flow sensor, easy to install, suitable for municipal sewers,不滿 pipe pipelines, various channels, irregular rivers, natural streams, drainage outlets, etc. for flow measurement, and can be concealed installed, can achieve long-term stable operation.
Instantaneous flow values and cumulative flow values can be provided.
2.8 inch color screen, text with graphics, convenient operation and fluid analysis.☆
Can store up to 10,000 pieces of data, and can be exported through the included USB flash drive.☆

Six, Use Requirements
1. The gas guiding cable contains a gas guide pipe, which cannot be overly bent to prevent it from breaking; never use the gas guiding cable as a rope for the Doppler flow meter, dragging the Doppler flow meter with the gas guiding cable;
2. The circular ultrasonic transducer in front of the probe cannot be impacted or scratched;
3. The instrument probe should avoid being exposed to the sun for a long time to prevent too high a temperature from causing a fault;
4. The acoustic doppler current meter should be regularly cleaned of silt on the ultrasonic transducer and pressure sensor in areas of high suspended sediment concentration to prevent the silt from blocking the pressure sensor.
