New method of measuring drop liquid and application

It is very difficult to measure drop liquid, so that a simple new method to measure drop liquid is presented in this paper. The method adopts pressure sensor to measure pressure of liquid, and then processes the pressure data to calculate the flowing rate of drop liquid. The experimental result shows that the method is not only satisfied with normal precise but also is constructed in low price. The method measuring drop liquid can be used in low flowing speed and thin diameter tubes and its precision is satisfied.
