Flow Meter Avery Hardoll Digital 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.
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 system conditions.
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.
