What is a magnetic level gauge and how does it work?
A magnetic level gauge uses a float with a built-in magnet that moves with the liquid level inside a chamber. As the float rises or falls, it drives an external indicator with magnetic coupling, providing a clear visual display without direct contact with the liquid.
What are the advantages of magnetic level gauges?
Magnetic level gauges offer:
- Clear visual level indication
- No direct contact between liquid and display
- High reliability in harsh environments
- Suitable for high temperature and pressure
- Support for remote transmission and alarms
They are ideal for safe and stable level monitoring.
What is the difference between magnetic level gauges and glass level gauges?
- Magnetic level gauges are sealed, durable, and suitable for high pressure and corrosive media
- Glass level gauges are fragile and have higher leakage risk
Magnetic gauges are preferred in industrial and hazardous applications.
Can magnetic level gauges measure interface levels?
Yes, magnetic level gauges can measure liquid-liquid interface levels (such as oil and water), provided there is sufficient density difference between the two media.
Where are magnetic level gauges commonly used?
They are widely used in:
- boilers and steam drums
- chemical storage tanks
- oil & gas industries
- industrial process vessels
They are ideal for high temperature, high pressure, and corrosive environments.
How do I choose the right magnetic level gauge?
Key factors include:
- measuring range and tank size
- medium density and properties
- temperature and pressure conditions
- need for remote output or alarms
- installation type (flange size, orientation)
Choosing the right model ensures safe and reliable level measurement.
