5. The flow rate into a certain unit operation through a flow control valve is permanently decreased by 90%. The flow control loop at this flow rate is unstable. Describe a simple change you can make to the measurement variable to reduce the instability without making any physical modifications to the control valve or flow meter.

There is an answer to this problem but is not the correct one. The correct one has to do with the control loop itself. Please do not forward me the answer that is already inChegg.

Thank you
