Automatic Flow Control and Applications

What is an automatic control system?

• A manual system requiring constant human monitoring.

• A system that operates independently of human intervention.

• A system that cannot function without human input.

• A system that requires occasional human intervention.

What is the purpose of a bleed in a flow control system?

• To introduce additional fluid into the system.

• To remove unneeded fluid through a separate opening.

• To increase the pressure within the system.

• To measure the fluid flow rate.

What does a bleed port do?

• Controls the main flow of fluid.

• Allows unneeded fluid to exit the system.

• Measures temperature changes.

• Seals the fluid within the system.

What is the function of the body in a flow control device?

• To transmit pressure changes.

• To measure fluid temperature.

• To support and house moving parts and seals.

• To control the flow of electricity.

How does a bulb function in control systems?

• By filtering the fluid.

• By expanding or contracting with temperature changes.

• By controlling fluid direction.

• By increasing system pressure.

What is calibration in control systems?

• Repairing broken components.

• Aligning operating values to a known standard.

• Estimating the temperature of the system.

• Decreasing the system's efficiency.

What is the primary use of a capillary tube in a control system?

• As a filter for impurities.

• As a pressure transmitter between sensing elements.

• To increase fluid flow rate.

• To reduce the system's overall temperature.

What is a diaphragm in control systems?

• A valve that controls fluid exit.

• A flexible membrane separating two chambers.

• A device to measure fluid pressure.

• A rigid barrier for fluid containment.

What does 'downstream' refer to in fluid flow?

• Fluid before it enters a flow controller.

• Fluid after it has passed through a flow controller.

• The initial point of fluid entry.

• The end point where fluid is stored.

What is a flange connection?

• A magnetic coupling in a flow system.

• A connection that uses bolts to link piping to components.

• A wireless connection method.

• A method using glue to connect piping.
