A Lonetti calibration test bench is a complete closed-loop test rig for verifying liquid flow meters — turbine, positive-displacement, electromagnetic, and Coriolis. The meter under test is plumbed into the loop; product flows from a reservoir, through the meter, into a certified reference (a prover tank or master meter), and back to the reservoir.
Each bench is engineered for the meter portfolio of the client: flow range, pipe sizes, end connections, accuracy class, and supported meter types. Common configurations support sizes from DN15 to DN100 and flows from 5 L/min to 1,200 L/min — but we have built benches for both smaller (fuel dispenser) and larger (terminal loading) ranges.
Benches ship with a documented procedure, calibration certificates for all reference standards, and the control panel necessary to run the loop unattended. Fixed and mobile configurations both supported.
6 properties that define a Lonetti test benches.
Specification points worth comparing against any other supplier — accuracy class, material grade, standards compliance, and configurability.
Closed-loop flow
Variable-speed pump, surge tank, return line — full flow recirculation, no waste of product.
Reference choice
Lonetti prover tank (gravimetric reference) or certified master meter (faster, suited for production). Both supported.
DN15 – DN100 standard
Standard pipe sizes from DN15 to DN100 (½″ – 4″). Larger sizes engineered on request.
Multi-meter support
Turbine, PD, electromagnetic, ultrasonic, and Coriolis meters — same bench, with adapter spools.
Control & instrumentation
PLC-based control panel with HMI, RTDs, pressure transducers, and data-logging output.
Fixed or mobile
Workshop installation or container-mounted mobile configuration for field meter shops.
Built to your spec, certified to ours.

The same engineering platform serves several distinct use cases. Configuration varies; accuracy class doesn't.
Meter shop workshop
Permanent installation at a meter calibration workshop, verifying multiple sizes per day.
OEM production test
End-of-line test rig for meter manufacturers — every unit tested before shipment.
Field meter shop
Container-mounted mobile bench for service providers serving distributed sites.
Lab reference
Research or metrology institute reference bench — typically with multiple master meters.
