Frequently Asked Questions

How does a propane tank gauge level indicator work?

A propane tank gauge level indicator uses a float mechanism connected to a dial or magnetic sensor. As the liquid propane level rises or falls, the float moves accordingly, translating the position into a readable level measurement. Stainless steel float balls are commonly used in these assemblies due to their corrosion resistance, pressure tolerance, and durability in sealed tank environments.

Can float balls be customized with specific thread sizes?

What sizes are available for round and oblong float balls?
