Avery-Hardoll flowmeters are precision made, positive displacement,
accurate metering over long
periods of operation. Simplicity of design and construction together
with sustained accuracy has led to the widespread use of BM Series
meters on aviation refuelling vehicles as well as master meters for use
in calibration throughout the world
Liquid Controls is committed to maintaining the decades long legacy of
Avery-Hardoll quality and precision in aviation fueling. Inside their state
of the art manufacturing and testing facility in Lake Bluff, Illinois, Avery-
Hardoll metering products are manufactured and vigorously 100% flow
tested before being put into service.
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
. Positive displacement measurement
. 115 to 4000 LPM (30 to 1000 GPM) flow rates
. Unequalled performance in measurement
The positive displacement principle is the ONLY accurate method of measuring
fluid flow. No other technology can achieve such accuracy because
measurement becomes inferred, which is indirect and subject to assumption.
The Avery-Hardoll® bulkmeter directly converts volume to rotational output with
minimum scope for error and with minimal disturbance from surrounding
conditions, eg. turbulence from nearby valves, bends, etc.
