| Abstract: | On the basis of the Pitot tube principle used for measuring fluid velocity in hydromechanics, a kind of compound sensor (consisting of one pressure sensor, and one pressure difference sensor) used for measuring velocity of fluid is developed. It deals with the measuring principle of the new type of sensor, the structural design and manufacturing of the sensor and chips, and lists the experimental results. This sensor can display the fluid pressure and pressure difference at the same time, beside this sensor has intellectualization to be used in unmanned fluid observation station. |
