The connection between the two Rotameters that is the orifice meter and the PDM acts as the entry for the airflow that passes through the pipe. As the air flows through these pipes, it gets to the end of the PDM, which in turn serves as the standard for measuring the airflow. Besides, the PDM act as the standard calibration tool for other meters. However, two components (thermocouple and the pressure gauge) are located beside the Rotameter while the orifice meter inhabits two pressure taps. The first step involves recording down the barometric pressure. Once the pressure is noted down, the air pressure is allowed to go through the system as its flow is controlled by the flow regulator. It is important to open the valve located at Rotameter 2. The value at this valve is noted and left constant rate for the entire experimental process. The next step involved opening valve at Rotameter 1 while increasing the flow rate steadily to avoid interfering with the valves from other meters to enable continuation of the process until the required value is obtained. The next step involved recording of temperature and pressure values recorded in Rotameter 1 and 2, as well as the value of dropping pressure from the orifice meter. Other parameters recorded include the time required for a given volume of air flowing via the PDM and PDM pressure. The validity of fluid mechanics experiments is contributed by the meters selected for measuring mass flow rate and the volume flow rate. This experimental design used different meters to understand these parameters. The meters were unique, for instance, the Rotameter with a float inside the tapered tube was used. It allows the entry of air at the bottom while the float points upwards to allow the air to the exit. One hindrance is the Rotameter geometry, which means that correction
