- Power efficiency: Auto-off LCD, long standby
- Units: GPM, LPM, QT, QTS, PTS, L, m³
Caution: Battery replacement requires access through a sealed housing; follow installation instructions to preserve waterproof integrity.
PHATRIP 1″ Turbine Fuel Flow Meter
Best for: kerosene, biodiesel, and light chemicals. This meter offers high accuracy up to ±1% and provides a 1″ NPT flow path with a 3/4″ adapter for versatility. It is suitable for fuel and chemical monitoring where precise data is needed.
- Accuracy: ±1%
- Display: LCD with real-time readings
- Adapters: 3/4″ included for compatibility
Limitation: Not recommended for water or gasoline in some configurations; confirm compatibility with your specific liquids before use.
Buying Guide
What should you consider when choosing a 1 inch flow meter?
- Liquid compatibility: Check whether the meter is rated for water, fuels, or chemicals and if the PTFE coating or corrosion resistance is needed for your liquids.
- Environmental conditions: If your installation is outdoors or in wet environments, choose a waterproof model (IPX8 or IP68) and EMI protection if interference is a concern.
- Accuracy and display: Look for ±1% accuracy and an LCD that clearly shows real-time flow, totals, and instantaneous values. Ensure unit options meet your reporting needs.
- Units and calibration: Ensure the meter supports the units you require (GPM, LPM, QTS, PTS, L, m³) and that calibration ranges fit your typical flow rates (e.g., 2.4-26.4 GPM vs. 2.6-26 GPM).
- Physical build: For lab or agricultural use, a durable metal housing with protective coatings can prevent damage and extend life.
- Power and maintenance: Some meters offer auto-off features or easy battery replacement. Consider how you’ll monitor and service the unit.
