Prepare a sketch, using ISA standard symbology for the following flow metering and control scenarios: The goal of this problem is to get your familiar with the different symbology in controls. 

a. orifice meter located on pipe A, independent P/I transducer, 4-20mAmp transmitter, independent field flow controller, independent 4-20 mAmp I/P transducer, pneumatically operated flow control valve located on pipe B

b. venturi meter located on pipe A w/ digital output, independent field flow indicator, plus centralized indicator in DCS

c. integrated mass flow controller w/ digital output located on pipe A plus centralized indicator in DCS

d. orifice meter located on pipe A w/ digital output, fieldbus-compatible flow control valve located on pipe B plus centralized indicated in DCS
