BM SERIES METERS

Avery-Hardoll bulkmeters are precision made, positive displacement, liquid measuring instruments,which maintain accurate metering over long periods of operation. Simplicity of design and construction together with sustained accuracy has led to the widespread use of these meters on aviation refuelling vehicles, in oil terminals throughout the world and also as master meters for use in calibration.

OPERATION

The positive displacement principle is the Oonly  accurate method of measuring fluid flow. No other technology can achieve such accuracy because measurement becomes inferred, that 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.
