NVFZ series magnetic float level gauge is a High precision and high reliability Liquid level measuring instrument, using Magnetic float drives reed switch Principle, combined 4~20mA two-wire transmission output , applicable to High temperature, high pressure, corrosive and flammable and explosive media Continuous monitoring of liquid level. On-site LED digital display , and optional standard, anti-corrosion and explosion-proof configurations, widely used in petroleum, chemical, electric power, pharmaceutical and other industries.
How it works The magnetic float level gauge works based on the principle of buoyancy and magnetic coupling. A set of dry tubes and precision resistors are installed in the detection tube. When the magnetic float moves up and down along the detection tube as the liquid level changes, the reed switches at the liquid surface in the detection tube are connected in sequence to change the output resistance value of the detection tube. The conversion circuit module in the junction box converts the resistance value into 4-20mA current output. Design Principle Simple structure, strong and reliable, stable operation The display indicates the liquid level in red, which is intuitive, eye-catching and easy to read. A variety of installation and connection forms are available. The measuring range is large and there is no blind spot in the whole process measurement. Continuous measurement of liquid levels of various liquids as well as high temperature, high pressure, corrosive and flammable and explosive media. The display is completely isolated from the measured medium, which is safe and reliable. Special designs are available for special pressures and temperatures. Product Model Product Selection Usage scenarios Magnetic float level gauge is suitable for liquid level display on containers of chemical, petroleum and other industrial equipment. At present, it has been widely used in liquid level measurement and control in petroleum, chemical, metallurgy, electric power, food, pharmaceutical, papermaking and other industries.
