Magnetic Gauging Device
Magnetic gauging devices are precision instruments used to measure and visually indicate the liquid level inside pressure tank cars without exposing the contents to the atmosphere. They utilize a magnetic float that rises and falls with the product level, transferring that movement to an external indicator for safe, accurate readings. In pressure tank car service, these devices play a critical role in monitoring fill levels, helping operators prevent overfilling, maintain proper outage, and ensure safe loading and unloading of pressurized commodities.
Continuous Visual Liquid-Level Indication
High-tech magnets are stronger and lighter, promoting durability and longevity. Standard float will accommodate commodity with specific gravity as low as .49. Single float systems available to accommodate specific gravity as low as .41. Tri-colored rod facilitates reading when car reaches critical fill level.
- Hermetically sealed rod prevents bleeding of easy-to-read numbers.
- Thicker Teflon float-bushings for longer float life.
- Float rated for 600 psig.
- All wetted components are stainless steel.
- 8” float provides increased buoyancy.
- DOT/Coast Guard compliant; approved by ABS (American Bureau of Shipping).
