[0002] Magnetic flap level gauges can be used for medium level detection in various towers, tanks, tanks, spherical containers, boilers and other equipment. This series of level gauges can be highly sealed, leak-proof and suitable for high temperature, high pressure and corrosion-resistant occasions.
