Magnetic level gauge is a tool used in industries to measure the level of fluids or liquids. It is consist of a floating device which can float in both high and levels. The float is a device whose ebbing and flowing affect its opening and closing of mechanical switch. For both magnetic and mechanical float level sensors, chemical compatibility, temperature, specific gravity (density), buoyancy, and viscosity affect the selection of the stem and the float. Its magnetic poles consist of two poles south and north south will read negative and north can read positive.
It is very important to choose right magnetic gauge its strength is hidden in magnetic field. It is heart of the magnetic level gauge. Its strength defines the quality and reliability of the product. The more strong magnetic field the more accurate and reliable gauge is. So it very considerable factor in choosing a magnetic level gauge.
The Area of application of a magnetic level gauge is very vast. It is used in many industrial places. The most common areas of application are Industrial boilers ,Oil/water separators, Flash drums, Surge tanks, Gas chillers, Deaerators, Blow down flash tanks, Hot wells, Vacuum tower bottoms, Alkylation units Boiler drums , Propane vessels, Storage tanks.
The features of a magnetic level gauge are Level indication viewable up to 150 feet away, No process liquid in contact with indicator glass, Ideal for high-temperature, high-pressure and corrosive applications, Magnetostrictive and radar transmitter options for non-invasive and/or redundant level control, Float failure indication (Standard), 360° magnetic coupling, Full corrosion resistance system, Measurement is unaffected by pressure, vacuum, temperature, foam and viscosity at design condition, Minimum sensitivity to density variation, Permanent local indication without external power supply, Optional adjustable alarm switches, Safe, environment friendly and trouble-free design.
