Manual Gauging

The gauging method is the simplest application you can install on tanks, not requiring cable runs.. This is normally through a GuardLevel®Sight Glass and gauge tree. The sight glasses are mounted on the top of the tank dome. Below the sight glass is a Visual Gauge tree.

The Gauge tree has level flags (innage/Ullage) at 6” increments annotating a level measurement. The sight glass has a hinged lid that the user opens to view through the glass the level of product in the tank. As the level rises it reaches a gauge tree flag and indicators product level.

Another manual method is a rising gauge stick or the GuardLevel®MDS (Magnetically Coupled Gauge Stick).

This float-based unit has a float attached to a 1” pipe. Inside the pipe is a tri-colored wand normal 1 meter in length. Attached at the bottom of the wand is a magnet. The top of the unit has a screw cap. The user removes the screw cap allowing the wand to rise with the magnet for a visual indication when the cargo is 1 meter or less from the top of the tank.

The top of the wand is colored Green indicating all well; the middle is Yellow indicating warning cargo is nearing overfill status; the bottom is Red indicating a possible overfill condition. Once the load is complete, the user disengages wand with float and lowers wand into unit, and screws cap back on.
