The orifice plate is used to estimate the flow rate of a mass flowing through a pipe by connecting the measured loss pressure and mass flow rate. In this paper, the relationship between Reynolds number (Re) and Cd is observed based on pressure variations in a pipe. The test results show that the release coefficient rapidly decreases when the Reynolds number approaches 1 for each meter of flow. By knowing the difference of the occurs pressure, the value of the parameter Cd can be calculated from the actual discharge ratio to its theoretical. The calculation results show that the average value of Cd for the orifice plate sensor about 0.599 (with a deviation value of about 0.001 and Re value around 10 5 is obtained.
