4) Write equations that could be programmed into a controller for the following conversions: a) 4-20 mA to 0 to 100 gallons b) 0-10V to 0 to 100 gallons c) 4-20mA to 50 to 500 pounds d) 4-20mA to 13 cfm to 26cfm (gas flow)
Note : Don't worry about amps , milli amps and volts and other units at the input and output side, equation will take care of it. Just concentrate on magnitudes only in the above all cases ( since the controller take care of magnitudes only ).
