Magnetic level gauge

Magnetic level gauges are highly accurate, low-maintenance alternatives to sight glasses and other outdated level indicators. They provide redundant, non-invasive level indication while eliminating leak points and fugitive emissions. Their robust design is ideal for high temperatures, high pressures and corrosive services

• 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

• Manufactured to meet ASME B31.1/B31.3 or PED 97/23 as specified

• Magnetostrictive and radar transmitter options for non-invasive and/or redundant level control

• Float failure indication (Standard)

• All external parts SS316 or as specified

• All external parts SS316 or as specified

• 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

• Safe, environment friendly and trouble-free design

• Indicating assembly certified to IP-66

Magnetic level gauges consist of a float chamber with process connections suitable for installation to the vessel. The process connections may be side couplings, flanges or other configurations.

The magnetic bar graph indicator is externally mounted to the float chamber; therefore, it is not a wetted part and is isolated therefore, it is not a wetted part and is isolated from the process. Flipper-style indicators are standard with bright, contrasting colours for clear and concise level indication.

The bar graph indicators are operated by the custom float installed in the chamber. Contained within the float is a 360° magnet Contained within the float is a 360° magnet assembly, which operates the external bar graph indicators through the chamber pipe wall. Floats are designed to meet the application process specific gravity and pressure, and are sized accordingly.

Service Fluid: Liquid Ammonia

Standard chamber

• Causes floats to sink

• Incorrect indication

• No space for vapors to pass

• Erratic movement of float inside the camber

Bliss’s Solution

• Smooth operation

• Oversized chamber (3”)

• Accurate level indication

• Float held between guide rods, closer to indicator

• Guide rods to allow vapors to pass through the vacant area

What is Cryogenics?

• Cryogenic liquids have boiling points below -240 °F

• It is a study of production of extremely low temperatures

• All Cryogenic liquids are gases at normal

• All Cryogenic liquids are gases at normal temperatures and pressures

• E.g.: Nitrogen, Argon, Helium, Hydrogen, Methane, LNG, Oxygen, etc.

Bliss’s Solution

• Oversized chamber (3”)

• Guide rods to ensure floats are closer to the

• Guide rods to ensure floats are closer to the indicating assembly • Acrylic frost extensions are provided

• Prevents frost accumulation and ensures clear visibility

• Special insulating material ensures the process fluid remains in liquid state at temp. up to -320_F Float held between state at temp. up to -320_F Float held between guide rods, closer to indicator
