Smart Tank™ monitors the floor you can’t see.

A tank floor is the hardest part of an AST to inspect and the most consequential to get wrong. Smart Tank monitors bottom-side corrosion rate, cathodic protection performance, and leak detection in real time — without taking the tank out of service, from the Gulf of Mexico to the Arctic.

Remote floor monitoring, without internal entry.

Standard practice is a scheduled internal inspection every several years, with the tank offline the whole time. Smart Tank replaces the blind years in between with continuous bottom-side data.

Remote AST floor monitoring — no internal entry required
Bottom-side corrosion rate tracked continuously, not just at turnaround
Cathodic protection performance and leak detection in the same unit
Field-proven from the Gulf of Mexico to the Arctic

The Smart Tank ultrasonic probe, held in hand at a field site

The Smart Tank probe — field-ready, hand-portable, and rated for direct burial.

One probe, permanently in place under the floor.

The yellow bands mark the probe's connector joints; the ruggedized black housing at the tip is the ultrasonic sensor itself, sealed against direct burial beneath the tank. Once it's in, it stays in — no re-entry, no recalibration trips.

Sealed for direct burial

No maintenance access required once the probe is in place beneath the tank.

Hand-portable to install

Sized for a one-person install, then permanent for the life of the tank floor.

Non-destructive

No coring, no cutting into the floor plate to get a reading.

Four steps, running continuously.

The same ultrasonic method used to inspect a tank floor by hand, running unattended underneath it, permanently.

Transmit

The probe acquires an ultrasonic reading through a corrosion coupon representative of the floor plate.

Reflect

The signal reflects back wherever corrosion or metal loss has changed the coupon's thickness.

Analyze

Onboard processing converts the reflection into a corrosion rate and metal-loss reading.

Report

Readings stream to the BSI dashboard alongside CP performance and leak-detection status.

Corrosion rate

Bottom-side corrosion rate is tracked continuously rather than estimated between inspections.

CP performance

Cathodic protection at the floor is monitored on the same continuous timeline.

Leak detection

Flags conditions consistent with a developing leak long before a scheduled internal inspection would.
