AI Technical Summary
In existing technologies, fluid velocity measurement is easily affected by environmental factors such as temperature changes, leading to inaccurate measurements.
Millimeter-wave radar is used to acquire the height information of each measurement point in the liquid in real time. By calculating the height change information per unit time and the total volume of the known liquid container, the flow rate of the liquid is calculated.
It enables rapid and accurate calculation of liquid flow rate, avoids the influence of environmental factors on the measurement, and improves the accuracy of flow rate calculation.
