Target Flow Controller As a crucial flow measurement and control device, it plays a vital role in industrial automation. Its precise measurement capabilities and efficient control system not only improve the stability and efficiency of the production process but also significantly reduce energy consumption and maintenance costs. This article will discuss Target Flow Controller the working principle, technical characteristics, application fields, and specific contributions to industrial automation in detail.

I. Working Principle of Target Flow Controller

The target flow controller is a flow measurement and control device designed based on fluid mechanics principles. Its core components include a target plate, sensor, converter, and actuator. When fluid flows through the target plate, the target plate is subjected to the impact force of the fluid, which is proportional to the fluid velocity. The sensor converts this force signal into an electrical signal, which is processed by the converter to output a standard signal proportional to the flow rate. The actuator adjusts the valve according to this signal to achieve precise control of the flow rate.

The specific working process is as follows:

1. Fluid impacts the target plate ：When the fluid passes through the pipe, it impacts the target plate installed in the pipe, generating a force proportional to the flow velocity.
2. Force signal conversion ：The sensor on the target plate converts the force signal into an electrical signal.
3. Signal processing ：The converter processes the electrical signal and outputs a standard signal (such as 4-20mA).
4. Flow control ：The actuator adjusts the valve opening according to the standard signal to control the flow rate.
