Question

A control system is to provide a regulation of flow in range of 20gal/min to 100gal/min. A linear flow sensor has a sensitivity of 0.1??/(gal/min) with 4mA  

at 20gal/min. The sensor has an uncertainty of ±6%.

a) What is the sensor current at 40gal/min?

b) What is the range of the output current at 40gal/min?

c) A current-voltage signal conditioning circuit with sensitivity of 0.4V/mA ±

5%; what is the output voltage range at 40gal/min?
