Built to resist corrosion and last in harsh environments, these vertical rulers are iron with a porcelain-enamel finish. Mount them to walls and tanks.

Fold these vertical rulers for convenient storage and transport.

Permanently mount these vertical rulers to walls and tanks.

Attach a plumb bob (sold separately) to the rope’s hook and lower it into your tank to take a measurement.

Using inches or centimeters instead of common levels, such as full or empty, these gauges are more precise than standard gauges when measuring liquid levels. They work with water, hydraulic fluid, or diesel.

Mount these gauges on the flat end of a horizontal, cylindrical tank to monitor diesel fuel, fuel oil, or gasoline level.

Measure water, hydraulic fluid, or diesel fuel level in your drum.
