FSI550 flow switch is an intelligent flow monitoring sensor based on the principle of thermal diffusion, this product adopts advanced industrial-grade MCU as the core, and uses a high-performance sensor and dedicated circuit. After temperature compensation and adjustment, the accuracy of measurement can be ensured even when the water temperature changes. The product can monitor the water flow in the pipeline in real time, it can also be used for cut-off monitoring of cooling or lubrication system, and provide early warning and protection for important equipment in case of flow failure. The product adopts fully enclosed design, and stainless steel structure is suitable for a variety of application environments. FSI550 has overvoltage, overcurrent and reverse connection protection, self-luminous OLED screen can switch display between progress bar and numbers. The action point can be quickly set by pressing the button, display reversal function can be installed in any direction, there is no need for frequent adjustment and maintenance. It can be applied for operation protection of large equipment in fields such as power generation, metallurgy, steel, papermaking, boilers, etc.
