Tanker trucks carry petroleum and chemical product across borders, refineries, and terminals — each compartment is a separately certified measure. Calibrating those compartments requires a vessel of equal volume, certified, and configured to allow controlled fill and drain.
Lonetti's tanker truck calibration tower stacks multiple prover tanks in a structural tower frame: typically two to five tanks of 500–5,000L per tier, with a top platform for operator access. The truck drives under the tower; product is drawn into the tower tanks, totalled, and compared against the truck's compartment indication.
This is a Lonetti specialty product — built to customer specification, installed permanently at terminals and refineries, or as a portable configuration for fleet calibration service providers. Every project is engineered around the truck fleet's compartment sizes and the available footprint.
6 properties that define a Lonetti tower systems.
Specification points worth comparing against any other supplier — accuracy class, material grade, standards compliance, and configurability.
Configurable tier count
Two, three, four, or five tiers — matched to the largest tanker compartment in your fleet.
Stainless or steel frame
Hot-dip galvanized steel tower frame standard; full stainless on request for aggressive media.
Per-tier ±0.05%
Each prover tank in the tower is INTI-certified to ±0.05% — totalled volume traceable to international standards.
Operator platform & ladders
OSHA-compliant access platform, sight glass for each tier, safety rails.
Permanent or portable
Permanent install at terminals, or skid/trailer-mounted for mobile fleet calibration service.
