Q

The difference between the setpoint and the measured parameter in an automatic flow controller is called:

🔍 Key Concepts

• Setpoint vs. process variable (measured value) in automatic control systems • The definition of error signal in basic control theory • How feedback uses the difference between setpoint and measurement

💭 Think About

• In a flow controller, what do you actually compare the setpoint to in order to decide whether to open or close the valve? • What is the technical term for the signal that represents this difference between desired value and actual measured value? • Which of the choices is a quantity that can change continuously as conditions change, rather than being a fixed setting or a general concept?

✅ Before You Answer

• Be clear on what setpoint means (the desired value) and what the measured parameter is (the actual value). • Ask yourself which choice is specifically defined in control theory as the difference between desired and actual values. • Eliminate answers that describe properties of the controller itself (like how strong it reacts) instead of the difference between two values.
