Name: MINILAB Mobile Calibration Van
Brand: Lonetti

Question 1

What is the Lonetti MINILAB®?

Accepted Answer

The MINILAB® is a Lonetti proprietary mobile calibration laboratory built into a van or box truck. It carries its own reference prover (200 L to 1,000 L), master meter, pump, instrumentation, and diesel genset — enabling traceable calibration at any remote site where meters cannot be removed from service. INTI-certified, ±0.05% accuracy.

Question 2

Is MINILAB® calibration traceable?

Accepted Answer

Yes. The onboard reference prover and master meter are INTI-calibrated and traceable to OIML R117 and NIST. The MINILAB® ships with full calibration documentation. Recalibration of onboard instruments is performed on a scheduled basis.

Question 3

Can I specify the MINILAB® vehicle?

Accepted Answer

Yes. Clients specify the chassis (make, model, fuel type, drivetrain) based on operating geography — diesel 4WD for remote or off-road sites, standard cargo van for urban routes. Lonetti integrates the laboratory onto the vehicle of choice.

Question 4

What meter types does the MINILAB® calibrate?

Accepted Answer

MINILAB® units handle turbine, positive-displacement, electromagnetic, ultrasonic, and Coriolis meters. Adapter spools for multiple pipe sizes (DN15 to DN100 standard) and required electrical interfaces are included onboard.

Question 5

Who uses the MINILAB®?

Accepted Answer

Users include: petroleum companies calibrating pipeline takeoff and loading-arm meters without removing them from service; national metrology institutes and state inspector fleets (INTI, INMETRO, IPEM); calibration service companies serving remote or offshore terminals; mining and agricultural operations with isolated fuel metering.

Question 6

What is the onboard prover capacity?

Accepted Answer

The onboard Lonetti prover tank is typically 200 L to 1,000 L, matched to the flow range and meter sizes in the client's fleet. A 200 L variant is common for fueling operations; 1,000 L is typical for pipeline or terminal meter proving.

Question 7

Does the MINILAB® require external power?

Accepted Answer

No. An onboard diesel genset (7 to 20 kVA) provides all electrical power. No external power or water supply is required — the MINILAB® is fully self-contained.

Question 8

What is the MINILAB® lead time?

Accepted Answer

16 to 28 weeks. Vehicle procurement is often the longest item on the critical path — availability varies by region and chassis specification. Contact us early in the project schedule.
