Avery-Hardoll flowmeters are precision made, positive displacement, liquid measuring instruments manufactured by Silea Liquid Transfer. In 2021, Silea acquired the Avery-Hardoll product line from Liquid Controls. Avery-Hardoll meter products including the BM series meters and MASTERLOAD.iQ™ electronic registers have been widely used on aviation refueling vehicles throughout the world.
With proven measurement accuracy as good as 0.05%, Avery-Hardoll meters remain unmatched in maintaining the most accurate fluid measurement in the world. The proprietary Avery-Hardoll meter design remains the industry benchmark that may have struggles to emulate, because "It's what on the inside that counts."
The first flowmeters built for aviation fuel. An ideal product to be installed on metering skids, for oil & gas applications.
BM Series Flowmeters
The BM series flowmeters is used widely for aviation refuelling vehicles as well as master meters for use in calibration throughout the world.
The BM series flowmeter directly converts volume to rotational output with minimum scope for error and with minimal disturbance from surrounding conditions, such as turbulence from nearby valves, bends, and other system conditions.
- Positive displacement measurement
- 115 to 4000 LPM (30 to 1000 GPM) flow rates
- Unequalled performance in measurement
DM Series Flowmeters
The Avery-Hardoll Steel DM Series flowmeters are precision made, positive displacement, liquid measuring instruments that maintain the highest level of accuracy over a lifetime of operation.
The DM meter is specifically designed to meet the rigorous demands of modern tank truck loading depots and fuel storage facilities as well as other niche applications.
It provides the highest level of pre-calibration repeatability and accuracy with industry leading ease of service without the inconvenience and cost of double-cased meters.
MASTERLOAD.IQ™ Electronic Register
Designed with the future in mind, the ATEX Zone 2 approved MASTERLOAD.iQ™ and Zone 1 MASTERLOADx.iQ™ introduce new capabilities for OEMs and end users to fully customize the fueling experience with configurable screens and tickets, adaptable software, real-time on-screen diagnostics, and remote data access with controls, opening the door to near-infinite platform expand-ability.
