(Fig. 2.2) In some instances, it might be desirable to use an external sensor to provide process information to the control circuitry in the flow controller. For example, you might want to control the pressure in a v...

141-072011 - 201/203 Series Page 21 of 23 D) This formula provides approximate results that tend to be undersized because it neglects pressure drops internal to the flow controller, compressible gas effects and temperature effects. Multiply the result by ≈ 1.5 to get the expected minimum orifice siz...
