AI Technical Summary

Technical Problem

In existing technologies, fluid velocity measurement is easily affected by environmental factors such as temperature changes, leading to inaccurate measurements.

Method used

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.

Benefits of technology

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.

Abstract

The application belongs to the technical field of measurement, and provides a liquid flow rate calculation method and device based on a millimeter wave radar, which comprises the following steps: acquiring height information of each measurement point in the liquid within a unit time in real time through the millimeter wave radar; obtaining height change information within the unit time based on the height information of each measurement point within the unit time; and calculating the flow rate of the liquid according to the height change information within the unit time and the total volume of a known liquid container. The height information of the liquid acquired through the millimeter wave radar is used to calculate the volume change of the liquid within the unit time, so that the flow rate of the liquid can be quickly and accurately calculated, thereby avoiding the problem of inaccurate flow rate calculation caused by environmental factors.
