Brodie Meter BiRotor Plus™ BiRotor Plus™

The BiRotor Plus™ meter is a volumetric flow measuring device designed for the accurate measurement of petroleum liquids in a variety of applications. This double case meter combines the rugged durability and long service life of the traditional BiRotor meter with the
improved accuracy and pulse output associated with today´s most sophisticated devices.

Utilizing single or dual outputs, with two non-wetted pickoffs mounted 90° out of phase, the BiRotor Plus complies with API Level B pulse output standards. Output signals are amplified and shaped by a preamplifier mounted directly on the meter for transmission to accessories
such as totalizing counters, digital readout devices, provers and other control equipment and instrumentation.

The inherent balanced rotor design makes the meter resistant to shock loads on the mechanism resulting from the shifting of off-balance masses or the introduction of
air slugs.

Typical applications includes loading/unloading, batching, blending and inventory control of petroleum products where accuracy and repeatability are the deciding factors in meter selection. It is recommended for loading and unloading tankers, railcars or trucks, pipelines, aircraft refueling, and general purpose flow measurement.

DESIGN FEATURES
• Superior performance: Linearity ±0.10% or better over 10:1 flow range; Repeatability ±0.01%
• Double case construction avoids loss of calibration due to changes in pressure or temperature
• New rotor profile provides high resistance to air slugs and entrained solids
• No metal-to-metal contact
• Dual pulse output meets Level B pulse security described in API manual, Chapter 5.5.4.4.
• Explosion proof amplifier housing
• Single or dual pulse output - non-wetted pickoffs
• Reduced number of parts reduces maintenance requirements.
• Variety of readout instrumentation available
• Horizontal or vertical mounting
• Class I, Division 1, Group C & D, NEMA 4X, UL, cUL and CENELEC Eex d II B T6, CE, NTEP
