Fiscal metering flow meters (BRODIE)
Description

Brodie International is a highly prestigious brand in high-accuracy liquid measurement for custody transfer of petroleum and derivatives. Its positioning draws on long experience in fiscal solutions, proprietary designs of critical equipment and an offering aimed at reducing uncertainty, protecting revenue and ensuring traceable and repeatable measurement.

In fiscal metering flow meters, Brodie is particularly distinguished by its positive displacement meters, including the BiRotor Plus family, developed to provide high accuracy and repeatability in custody transfer, loading and unloading, blending and measurement in marine applications.

The Brodie BiRotor Plus is a dual-casing positive displacement meter with twin helical rotors and non-wetted pick-offs, generating a precise and very stable pulse signal for the measurement of liquid hydrocarbons.

It offers linearity of up to ±0.075% and repeatability of 0.02%, operating in viscosity ranges of 0.2 to 1000 cSt, with low pressure drop and the possibility of vertical or horizontal mounting. For fiscal measurement it is an ideal solution as it has OIML R117/MID certifications, maintains high meter factor stability, shows low sensitivity to viscosity and density variations and is easy to prove with compact or small volume provers.

The brand complements the meters with control valves, filters, air eliminators and also offers modular or skid-mounted systems, creating a complete measurement architecture for terminals, networks and final measurement points.

Its natural market is crude oil, jet fuel, gasoline, diesel, renewable fuels (SAF) and bunkering, terminal, transport and custody metering applications.

Brodie provides a genuinely specialist offering for metering, with a clear impact on accuracy, traceability and protection of the value transferred.

Other Features

The Brodie BiRotor Plus stands out for its extraordinary linearity: in certain sizes it achieves ±0.075% over the standard range, with a repeatability of 0.02%, placing it among the elite of PD volumetric measurement for custody transfer.

This clearly improves the ±0.10%–±0.15% typical of other market alternatives, reducing meter deviation and maintaining a more uniform response across the entire operating range.

In fiscal metering this is decisive, because the invoiced volume depends on the meter factor obtained during proving and any additional variation increases system uncertainty and the economic exposure of each transaction.
