A Guide in Selecting the Right Mag Gage for Specific Applications

A magnetic gage, also called mag gage, is a deviceused for obtaining the liquid level measurements inside processing vessels.Selecting the appropriate magnetic gage for a specific application is important. Use the following questions to review your requirements and establish a set of criteria for selecting the right mag gage for the application. Let this guide provide you with the key to help you make informed gauge decisions.

1. What is the process fluid?
• What is the specific gravity?
• What is the operating temperature?
• What is the operating pressure?
• Does it come with total, interface, or dual-level detection?

2. What are the gauge body details?
• What is the material of construction?
• What is the maximum pressure requirement?
• What is the necessary level range (fluid fluctuation—often the vessel height)?
• Does it have vent and drain connections?

3. What are the process connection details?
• What is the size?
• What is the tyoe?
• What is the rating?
• What is the orientation and position?

4. What type of indicator is preferred?
• Does it have flag (orange/black, yellow/black, red/white)?
• Does it have shuttle?
• Does it have color indicators?

5. What measuring scale is required?
• Does it measure level in inches, feet, and/or meter?
• Does it measure volume in gallong, liters, or custom?
• Does it measure percentage of liquid saturation?

6. What accessories are necessary?
• Does it have switch function and type?
• Does it have level transmitter?
• Does it have frost extension (required for cryogenic applications)?
• Does it do heat trace?
• Does it have high or low-temp insulation?
• Does it have magnetic traps?
• Does it have gauge glass?
