Tanker Truck Liquid Calibration Tower Systems
A tanker truck calibration tower is a multi-tier installation of certified prover tanks stacked in a structural tower frame, used to verify the volume of each compartment of a tanker truck or cistern vehicle. Lonetti has manufactured calibration towers for petroleum terminals, refineries, and fleet operators across South America, Africa, and the Middle East since the 1980s.
What is a tanker truck calibration tower?
The truck drives under the tower; product is transferred from each compartment into the tower's stacked prover tanks. The totalled volume is compared against the truck compartment's indication. Each Lonetti prover tank in the tower is INTI-certified to ±0.05%, giving a traceable combined measurement across the full tanker capacity.

When do I need a tanker truck calibration tower?
- Terminal fleet calibration: Permanent installation at petroleum terminals, refineries, and bulk-distribution depots.
- Periodic recertification: Annual or biennial recertification of tanker compartments as required by national regulators.
- New-build commissioning: Initial certification of newly fabricated tanker truck compartments before commissioning.
Frequently asked questions about calibration towers
How accurate is the total measurement?
Each Lonetti prover tank in the tower is certified to ±0.05% by INTI. The combined system accuracy is typically ±0.05% – ±0.1% across the full tanker capacity, depending on configuration.
Is this a portable or permanent installation?
Both are available. Most clients order a permanent install at a refinery or terminal, but skid- and trailer-mounted configurations are built for calibration service providers serving multi-site fleets.
What is the lead time?
Tanker truck calibration towers are custom projects — 20 to 32 weeks depending on configuration, foundation requirements, and certification scope.
