The MINILAB® is a Lonetti proprietary product — a fully equipped liquid calibration laboratory built into a van or box truck. It travels to the meter, not the other way around. Self-contained: it carries its own reference prover, pump, control instrumentation, and power supply.
MINILAB® is used by petroleum companies, national metrology institutes, and inspection bodies that need to perform traceable calibration at remote sites — pipeline takeoffs, offshore terminals, mining operations, agricultural depots — where the meters cannot be moved to a workshop.
Each MINILAB® is configured to the client's meter portfolio: reference vessel size, master meter range, supported meter types, and the inspection documentation system. The van itself is selected for the operating geography — diesel, gasoline, 4WD, refrigerated, depending on the route.
6 properties that define a Lonetti calibration laboratories.
Specification points worth comparing against any other supplier — accuracy class, material grade, standards compliance, and configurability.
Self-contained operation
Onboard genset, pump, reservoir, and instrumentation — no external power or water required.
Reference prover onboard
Lonetti 200L–1,000L prover tank built into the van — INTI-certified, traceable.
Master meter included
Faster verifications via certified master meter; cross-checked against the onboard prover.
All meter types supported
Turbine, PD, electromagnetic, ultrasonic, Coriolis — adapter spools onboard.
Climate-controlled cabin
Insulated and air-conditioned work area for hot or cold operating environments.
Complete documentation kit
Onboard PC with calibration software, certificate templates, and audit-trail data export.
Built to your spec, certified to ours.

The same engineering platform serves several distinct use cases. Configuration varies; accuracy class doesn't.
Remote pipeline calibration
Pipeline takeoff meters where the meter cannot be removed from service.
Offshore & marine
Loading-arm meters at marine terminals and offshore platforms.
National metrology service
INTI / INMETRO-style state inspector fleets serving regional weights & measures.
Mining & agriculture
Fuel and chemical metering at remote operations where workshops aren't an option.
Workshop, field, and deployment.
