Selecting and Using Magnetic Level Indicators (MLIs)
When it comes to managing fluid levels in industrial applications, Magnetic Level Indicators (MLIs) provide a reliable and highly visible solution. Used across industries such as oil and gas, chemical processing, and water treatment, MLIs excel in environments where precise level monitoring is essential. In this post, we’ll explore key factors in choosing the right magnetic level indicator and its application in various scenarios.
Understanding Magnetic Level Indicators
A Magnetic Level Indicator consists of a float with a magnetic element inside, a measuring tube, and a visual indicator. As the fluid level changes, the float rises or falls, rotating a magnetic indicator to reflect the level. This system provides real-time, highly visible level readings without needing electronic components, which enhances durability and reliability in demanding environments.
Selecting the Right Magnetic Level Indicator
1. Application Requirements
Start by assessing the specific needs of your application. Consider:
- Fluid Type: Is the fluid corrosive, viscous, or hazardous? MLIs come in various materials, including stainless steel, PTFE lining, and exotic alloys, to withstand different fluids.
- Temperature and Pressure: High-temperature and high-pressure applications require materials and designs rated to handle extreme conditions. VACORDA MLIs can handle temperatures ranging from -196°C to 350°C and pressures up to 25 MPa.
- Density and Viscosity: The float's buoyancy is influenced by fluid density, and highly viscous fluids might require specialized designs to ensure smooth operation.
2. Indicator Options
Choose an indicator that matches the viewing requirements. VACORDA offers MLIs with standard visual indicators and options for remote transmitters, which allow for digital monitoring and connectivity with control systems.
3. Mounting Orientation
- Vertical and side-mounted configurations are commonly used, depending on the available installation space and tank design.
- For applications with limited space, side-mounted MLIs offer an optimal solution while maintaining the functionality of a traditional MLI.
Typical Application Scenarios
1. Oil & Gas Industry
Magnetic level indicators are particularly popular in the oil and gas sector for their durability in high-temperature, high-pressure environments. MLIs provide clear, reliable level indication in storage tanks, separators, and other essential equipment, offering robust resistance to corrosive substances.
2. Chemical Processing
Chemicals often require corrosion-resistant materials, making stainless steel or PTFE-lined MLIs ideal choices. In addition, hazardous fluid containment is enhanced by MLIs as they provide a fully sealed, leak-free design that ensures both safety and environmental protection.
3. Water and Wastewater Treatment
In water treatment plants, MLIs help operators monitor tanks and reservoirs with high accuracy, and VACORDA MLIs can be equipped with guided wave radar or remote level transmitters for integration into SCADA systems, enhancing automation and ease of use.
Installation and Maintenance Tips
Proper installation ensures your MLI performs optimally. Ensure the level indicator is mounted securely and aligned vertically to avoid float sticking or inaccurate readings. Additionally, performing periodic maintenance checks can extend the unit's service life and prevent clogging or buildup.
