A sensor converts flow linearly so that flow rate from 0 to 300 m3/h becomes a current from 0 to 50 mA.
(i) Find a linear equation between output current and flow rate.
(ii) Calculate the output current when flow rate is 210 m3/h.
(iii) The output current increases from 0 to 15 mA in 5 seconds when there is a sudden inrush from 0 to 210 m3/h. What is the sensor time constant?
