- 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.
