In modern industrial automation systems, target flow controllers as an important flow measurement device, are widely used in the petroleum, chemical, and power industries. Its core function is not only to monitor and control flow in real time, but also to implement data logging functionality. Data logging helps companies better analyze flow changes during the production process, optimize processes, and improve production efficiency. So, how is the data logging function of a target flow controller implemented? This article will provide a detailed analysis from three aspects: working principle, technical implementation, and application scenarios.

I. Working Principle of Target Flow Controller

A target flow controller is a flow measurement device based on mechanical principles. Its core component is a target plate When fluid passes through the pipe, the target plate will be subjected to the impact force of the fluid, which is proportional to the fluid's velocity and density.
