The principle and fault analysis of magnetic flap level gauge. Magnetic flap level gauge can be used for medium level detection of various equipment such as towers, tanks, tanks, spherical containers, and boilers. Magnetic flap level gauges can achieve high sealing, leak prevention, and are suitable for high temperature, high pressure, and corrosion-resistant applications. It compensates for the defects of poor clarity and easy breakage of the glass plate (tube) level gauge, and the entire measurement process has no blind spots, showing ..
