Input Data of resistance reading taken from thermal flow meter, which contains distortion. Filter the distorted resistance using a 3 point average. Using the calibration curve equation y = 5.1981x + 1.7762, change the resistance data of the filtered and unfiltered resistance into temperature. Plot a graph of temperature vs. time of the filtered and unfiltered temperatures. The graph of the filtered temperature shows the fluctuation in the temperature, which is proportional to the fluctuation in the flow rate. This allows us to control the flow rate and maintain a constant flow. Find the change in temperature from the values found from the calibration eqn

Unformatted text preview: • Find the mass flow rate using the temperature reading taken from the thermal flow meter. Using the equation T C R i m p ∆ = 2 , where i=2.5amps and r =1 k Ω and the Cp = 4.1813 J/gK. • Find amount of flow need from control valve which is 1- mass flow rate of pipe. Then change it into Percentage. • Output two valves one which the flow passing through the flow meter and the other the control valve which supplements it, to maintain a constant flow of 10 kg/min. Display data in percentage on two indicators on front panel....
