Why Use Magnetic Level Gauges?
Magnetic Level Gauges (MLGs) are a robust, low-maintenance solution for industrial liquid level measurement. Their reliable, mechanical operation eliminates many challenges associated with electronic or invasive systems. Here’s why MLGs are the superior choice:
Maintenance-Free and Cost-Effective
No Calibration Needed: Operates without recalibration, simplifying maintenance and reducing downtime.
Corrosion-Resistant Materials: Constructed from materials like Stainless Steel, Titanium, Hastelloy, and PTFE coatings, ensuring long-term durability even with aggressive or corrosive media.
Energy-Free Operation: Requires no external power source for basic level indication, reducing operating costs.
Continuous and Clear Visibility
Real-Time Monitoring: Provides uninterrupted level indication with bright, contrasting visual markers for easy reading.
Long-Distance Readability: High-contrast colors ensure visibility from up to 200 feet, even in poor lighting conditions.
Scale Durability: Laser-etched or engraved scales resist wear and environmental damage, ensuring long-lasting clarity.
Mechanical Reliability
Non-Electronic Operation: MLGs function entirely on mechanical principles, using a magnetically coupled float system. No electronics, guidewires, or powered components are required, making them inherently reliable and resistant to failure.
No Internal Tank Components: All measurement components are housed externally, with no intrusion into the tank or process fluid, ensuring safe, maintenance-free operation.
Enhanced Safety
Sealed and Isolated: The chamber and indicator are completely sealed, preventing leaks, emissions, or contamination from hazardous or corrosive fluids.
Durable in Harsh Conditions: Handles extreme pressures (up to ANSI Class 900) and temperatures (up to 450°C) without compromising safety or performance.
Shatterproof Alternative: Replaces fragile sight glasses, minimizing risk to personnel and equipment.
Principle of Operation
How It Works
Float Mechanism:
A sealed float containing a permanent magnetic assembly is designed to remain buoyant in the process liquid, submerged approximately 70-80% based on the fluid's specific gravity.
As the liquid level rises or falls, the float moves correspondingly within the external chamber.
Magnetic Coupling:
The float’s magnetic field is coupled to the external visual indicator mounted on the chamber.
This ensures the indicator moves synchronously with the float, providing an accurate representation of the liquid level without the need for direct process contact.
Visual Indication:
The indicator is comprised of rotating flags or rollers in contrasting colors, which flip to reflect the liquid and vapor levels.
The movement provides an intuitive, real-time visual display of the liquid level.
