In modern technology, Doppler flowmeter and radar are two common technologies. They each play important roles in their respective fields, but what kind of sparks do they generate when combined? This article will provide a detailed introduction to the principles of Doppler flowmeter and radar, as well as how they can be combined to provide us with more accurate and efficient services.

Applicable occasions: This radar Doppler flowmeter is an instrument used to measure the flow velocity and water level of water in natural water bodies. The working frequency of the ranging radar unit is 80GHz, and the working frequency of the speed measuring radar unit is 24GHz. The measurement point is located in front of the body and does not disrupt the flow field. It is suitable for measuring in rivers with high suspended sediment content, abundant floating debris such as aquatic plants, and extremely harsh ice age conditions. It can be widely used for flow monitoring in water level monitoring stations, irrigation canals, sewage and rainwater pipe networks, etc.

A Doppler flowmeter is an instrument that uses the Doppler effect to measure fluid velocity. The Doppler effect refers to the phenomenon where there is a difference between the frequency of the wave received by the observer and the frequency emitted by the wave source when the wave source and observer are in relative motion. In fluid measurement, a Doppler flowmeter emits ultrasonic waves and then receives the reflected ultrasonic waves. By analyzing the frequency changes of the ultrasonic waves, the velocity of the fluid can be calculated

Radar is a wireless device that uses electromagnetic waves to detect the position, velocity, and other characteristics of a target. The basic working principle of radar is to emit radio waves and then receive the reflected radio waves. By analyzing the characteristics of the reflected radio waves, the position, velocity, and other features of the target can be determined.

How are Doppler flow meters and radar combined? In fact, the combination of Doppler flowmeter and radar is mainly reflected in the process of measuring fluid velocity. During this process, the radio waves emitted by the radar are reflected back by the fluid and then received by the radar. By analyzing the frequency changes of the reflected radio waves, the velocity of the fluid can be calculated. This is the basic working principle of combining Doppler flowmeter and radar.
