Boyd Mechanical Spiral Float Level Gauge

The Boyd Mechanical Spiral Float Level Gauge uses an aluminum extrusion riser and a vertical float to measure liquid levels in tight spaces with accuracy. The clear lens and needle is fully sealed and does not penetrate the tank so there is no leak points above or below the gauge. We offer this gauge in multiple lengths shown below.  you will measure your tank overall height then find the closest gauge thats below the height measured. Example:  Tank height = 12"  Choose 11.5" Gauge length This Gauge Mounts using the industry standard 5 bolt pattern.  Any of our weld on level sensor flanges will work. Click here for flanges.
