About The MFM500A Flow switch
The MFM500A Flow Switch is an intelligent flow monitoring sensor based on the thermal diffusion principle. Utilizing an ARM processing core combined with high-quality sensors and specialized circuitry, this device ensures precise flow measurement, even with fluctuations in water temperature, thanks to its built-in temperature compensation and calibration features.
Real-time flow monitoring and equipment protection
Designed for real-time monitoring of water flow in pipes, the MFM500A is ideal for cooling and lubrication systems. It provides early warnings and protective measures for critical equipment in case of flow faults, helping to prevent damage and downtime.
Durable construction and versatile functionality
The MFM500A features a fully enclosed, stainless steel design, making it suitable for a wide range of environmental conditions. It offers comprehensive protection with overvoltage, over-current, and reverse polarity safeguards. The self-luminous OLED screen allows for easy monitoring, with the option to switch between a progress bar and digital display. Additionally, it supports quick action point settings and features a display inversion function, enabling installation in any direction without the need for frequent adjustments or maintenance.
Ideal for Industrial Applications
This flow switch is perfect for protecting large-scale equipment across various industries, including power generation, metallurgy, steel production, paper manufacturing, and boiler operations. Its robust design and intelligent features make it a reliable choice for ensuring the smooth operation of critical systems.
