Right Gauge, Right Tank — Verified Before It Ships

Ordering a liquid level gauge that doesn't match your tank's bung threads or depth range wastes time and creates downtime on the job site. Tank Vault eliminates that risk. Before your order ships, we verify your tank depth, bung size, and fluid type to confirm the Black Knight Gauge is built-to-spec for your application. The 2-inch NPT threads interface with standard tank bungs, and the 99-inch measurement range covers most aboveground storage tanks. We catch compatibility problems before the box leaves our facility — not after it arrives on your site and doesn't fit.

No Chain Snags, No False Readings

No Chain Snags, No False Readings

The oversized aluminum float assembly is a field-proven design that rotates freely inside the tank, preventing the nickel-plated brass chain from tangling around internal baffles or supports. Chain entanglement is the most common cause of inaccurate gauge readings on bulk storage tanks — and it forces unnecessary dipstick verifications or, worse, running a tank dry. The direct drive mechanism transfers float movement directly to the large number display without intermediate linkages that introduce play. The molded housing protects the gauge body from impact and weather exposure at the top of the tank.

Read Your Tank Level from Ground Level

Read Your Tank Level from Ground Level

The large number display on the Black Knight Gauge is engineered for visibility without climbing the tank or using binoculars. After installation through the 2-inch NPT bung, the new swivel mechanism lets you orient the gauge face in the direction you need — toward your fuel truck, your pump station, or your office window. The gauge measures from 99 inches down to zero, giving you a clear numerical reading instead of estimating from a sight gauge or dipstick. Molded housing and direct drive construction keep the mechanism stable in outdoor conditions.

“Installed on our 1,000-gallon diesel skid tank. Large numbers are easy to read from the pump island, and the swivel let me point it exactly where I needed. Tank Vault confirmed my bung size before I ordered — no surprises.”
