Description
The FLOMEC QM40 uses oval gear technology with a frictionless magnetic drive to deliver high-accuracy diesel measurement without internal seals. No calibration is required out of the box — the meter is factory set to ±1% accuracy with ±0.5% achievable in the field. Ideal for gravity-fed applications due to low pressure drop.
Features
- Oval gear technology — 20× more precision at 75 LPM and 4× higher overall accuracy compared to nutating disc meters
- Frictionless magnetic drive — no internal seals, no internal leaks, extended service life
- No calibration required; factory set at ±1% accuracy with ±0.5% achievable in the field
- Accurate down to 8 LPM — significantly lower minimum flow than nutating disc meters (24 LPM)
- Flow range of 8–150 LPM — 33% greater capacity than typical nutating disc mechanical meters (120 LPM)
- Low pressure drop: 1 PSI at 40 LPM · 7 PSI at 150 LPM — ideal for gravity-fed installations
- Rotatable display mount for flexible installation orientation
- Quick-Fit modular feature with four-bolt connection for easy attachment to modular fuel transfer pumps
- Recommended for diesel transfer and measurement on gravity-fed systems
Applications
- Diesel fuel dispensing and transfer
- Fleet operations and heavy equipment refuelling
- Agricultural equipment refuelling
- Recreational product fuelling
- Aviation refuelling
