Avery-Hardoll flowmeters are precision made, positive displacement,
liquid measuring instruments that maintain 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.
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.
