Magnetic Level Gauge MLG 20-55

Working Range: Magnetic Level Gauge type MLG 20-55 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.

Function: 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.

Installation: MLG 20-55 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.

Installation Samples: This device is installable on tanks and other relevant places vertically from the connected flanges. To order this product, the position of tank and the distance of first connection flange from foundation (A) should be taken in to account. When such a distance is not possible, it is necessary to make major coordination with the manufacturer. When side to side installation of the device is not possible, top-mounted design can be manufactured. Below images are various types of level gauge installation.

Advantages of using Magnetic Level Gauge

1. Due to the lack of mechanical and electrical connection between the parts inside and outside the liquid, this device can be installed with more safety.
2. Possibility of monitoring the liquid level of reservoirs from far distance
3. Possibility of change the sight angle of indicator plate
4.  Resistant and leak proof.
5. Makeable for high temperature and working pressure
6. Makeable for top and side mounting
7. Possibility to send electrical commands (ON-OFF) or transmit (4-20 mA) or current (0…10V)
8. Possibility to adjust sensors mounting positions
9.  Possibility to use more sensors to increase the safety factor of the device.
