Description

Technical Field

[0001] The utility model relates to the technical field of flow radars, in particular to a flow measurement radar capable of automatically adjusting its angle. Background Art

[0002] In many industrial and agricultural applications, it is very important to accurately measure the flow rate of liquids. Traditional flow measurement methods usually use devices such as rotary wings, turbines or ultrasonic sensors. Flow radar is one of them. It can measure flow rate, flow rate, water volume, etc. It measures flow rate accurately, has high measurement accuracy, wide range, can measure weak flow, and strong flow. It should be sensitive, have high resolution, and have a small starting flow rate.

[0003] For example, Chinese patent publication number CN217109030U discloses “a flow radar that is easy to install, including a radar flow meter, a stand and an installation adjustment mechanism, wherein the radar flow meter is installed on the lower surface of the stand through the installation adjustment mechanism, and the installation adjustment mechanism includes a fixed plate, a slide rail and a sliding sleeve, and a rotating assembly, wherein the slide rail is fixed to the upper surface of the radar flow meter through a countersunk screw, and two sliding sleeves are arranged on the slide rail, and a limit screw is arranged between the two, and the two fixed plates are horizontally fixed to the front and rear surfaces of the stand respectively through screws, and the rotating assembly is installed on the upper surface of the sliding sleeve, and an adjustment assembly is arranged between the rotating assembly and the fixed plate”;

[0004] This type of patent sets a "rotating component" to make the "radar velocity meter" rotate on the vertical plane, thereby achieving angle adjustment of the "radar velocity meter"; this adjustment method mainly adjusts the angle of the "radar velocity meter" manually, which may lead to measurement errors, and this adjustment method can only adjust the "radar velocity meter" in one direction, and as the fluid, flow rate and flow direction change, the "radar velocity meter" needs to be adjusted in multiple directions, and this patent cannot meet the requirements of multi-directional adjustment of the "radar velocity meter", which will cause large errors in the measurement data of the "radar velocity meter"; furthermore, the method of manually adjusting the angle of the "radar velocity meter" in this patent responds slowly to changes in flow rate and flow direction, and cannot adjust the angle of the "radar velocity meter" in real time to adapt to different flow conditions, especially for low flow rates. The signal-to-noise ratio is a key factor that directly determines whether the measurement can be accurate. How to maximize the signal-to-noise ratio of radar reception is difficult to meet this requirement by manual adjustment. Utility Model Content
