Magnetic Level Gauge type MLG-55 is used to determine and control the level of liquids (from 0.3 up to 18 meters). Its working attributes are: PN16 to PN250 working nominal pressure, 150/1500 working class, 1/2" to 2" flanged connection and 1/2" to 1"screwed connection and 555°C or 1031° F working temperature. This device is produced base on DIN or ANSI standard and used in water, fuel, acid, chemical tanks and also in steam, hot water caldrons, oil, Gas, petrochemical and pharmaceutical industry.
This device has been designed based on the physical principles, fluids pressure, electromagnetic property, attraction and repulsion of poles. The body of the level gauge is a tube which is connected to reservoir vertically from the related flanges. The fluid inside the reservoir is directed to the tube through the bottom nozzle, and it makes float the magnetic ball. When the level of liquid is changed, the floater ball is moved and it faces the flaps, then changes their color, and consequently the liquid level of tank can be observed. By using the sensors which are mounted on this device, required commands are directly sent to its main electrical panels or with other electronica panel, the liquid level inside reservoirs can be controlled and fixed at the slightly height automatically by start and stop of feeder electro pumps, or level transmitter can be installed on this device and sending output current (4…20 mA) or (0…10V) to PLC to see and control the level of liquid in various position.
MLG55 Level Gauge is manufactured base on center to center distance of flanges which client orders them. Then it is installable via flanges placed on the tanks. After attaching flanges of the device to flanges on the tank and getting assure of its sealing, open blind flange and place the ball within the main tube regarding the arrow mark on it. Then re-attach the blind flange carefully and fill the liquid within the level gauge. Then ball floats on the fluid and it goes up to the liquid level.
