Flow Control System

CONSTRUCTION

  1. The flow control system is consists of a tank, where the liquid is placed.

  2. It is also consists of a pipe, the orific plate is placed in the pipe.

  3. That orific plate is connected to the transmitter.

  4. The transmitter is then connected to the controller.

  5. The controller is connected to the control valve, through which the flow of liquid is to be controlled.

Flow Control

WORKING

If the pressure of the flow is increased, that pressure is sensed by the orific plate. The orific plate will passes that signal to the transmitter. The transmitter will transmits the signal to the controller, where the pressure signal will compared with the set point value. And if the pressure is more than the set point value, the control valve will be automatically closed by the controller. Then the flow will be decreased to the set point value.

If the pressure of the flow is decreased, that pressure is sensed by the orific plate. The orific plate will passes that signal to the transmitter. The transmitter will transmits the signal to the controller, where the pressure signal will compared with the set point value. And if the pressure is less than the set point value, the control valve will be opened by the controller. Then the pressure of the flow is increased near the set point value.
