GRYVOZE 1 Inch Digital Turbine Fuel Flow Meter
The GRYVOZE 1 Inch digital turbine flow meter delivers precise liquid measurements with an accuracy of ±1%. It supports a range of fuels including water, diesel, gasoline, and kerosene, making it suitable for aviation-related fuel testing in sheltered environments. The device features a digital LCD display showing real-time flow and accumulated totals for straightforward monitoring. Note that the unit is intended for dry environments and should not be exposed to rain or moisture.
GRYVOZE Waterproof 1 Inch Flow Meter
This GRYVOZE model is fully waterproof, designed for use in wet environments. It includes EMI protection to prevent false readings from nearby electrical equipment, and supports switching between units such as gallons, quarts, pints, and liters. Its flow range (2.4-26.4 GPM) covers typical aviation fueling scenarios and it’s built for durability in challenging conditions.
GPI – 01A Series Turbine Flow Meter
The GPI 01A turbine flow meter is compact and lightweight, featuring a battery-powered digital display. It’s compatible with gasoline blends up to E15 and diesel blends up to B20, including kerosene. The package includes the meter, rubber bumper, reducers, fittings, and batteries. It’s suitable for portable fuel transfer tasks and small-scale aviation fueling applications where water and other chemicals are not involved.
GRYVOZE 3/4 Inch Digital Turbine Fuel Flow Meter
This model offers ±1% accuracy with a 0.8-13.2 GPM flow range, suitable for diesel, gas oil, gasoline, and other liquids. It employs a digital LCD display for real-time readings and totals. Caution notes indicate it is not waterproof and should avoid water exposure; factory testing uses paraffin oil, which may emit a slight odor that cleaners can remove. It includes EMI protection to minimize interference.
GRYVOZE 3/4 Inch Digital Turbine Fuel Flow Meter (Enhanced)
This enhanced variant features a larger internal diameter for cleaner threading, improved PTFE sealing guidance to prevent leaks, and EMI protection. It supports multiple units including gallons, quarts, pints, and liters, making it adaptable for aviation fueling tasks that require flexibility in measurement units. Note that the product is not waterproof for immersion in liquids.
YFIXTOOL 1″ Mechanical Fuel Meter
This mechanical meter offers a large-screen display with four digital subtotals and an eight-digit total. It’s designed for high-viscosity liquids like diesel and engine oil and can be oriented horizontally or vertically. It’s suited for fuel transfer pumps where electronic display is not required, complementing electronic meters in mixed-fuel setups.
Buying Guide: Key Purchase Considerations
- Fuel compatibility: Ensure the meter supports the fuels you handle (gasoline, diesel, kerosene, etc.). Some meters are designed for water and other liquids, while others are limited to specific fuels.
- Accuracy and flow range: Look for meters with ±1% accuracy and a flow range that covers your typical usage, such as 2.4-26.4 GPM or 0.8-13.2 GPM for smaller lines.
- Environmental protection: For workshop or sheltered use, a dry environment-rated unit may suffice. For wet or outdoor environments, prefer waterproof (IP-rated) models and EMI protection to prevent interference.
- Display and logging: Digital LCD displays simplify live monitoring and totals. Consider units with clear totalization (e.g., 99,999 counts) for longer-term tracking.
- Installation and compatibility: Check NPT thread sizes (1 inch, 3/4 inch) and whether adapters are included. Some models require PTFE tape or specific sealing procedures to prevent leaks.
- Durability and maintenance: Mechanical meters offer rugged simplicity, while digital units may require care to avoid moisture exposure. Review maintenance notes about cleaning and odor from factory testing fluids.
- Power source: Battery-powered displays are convenient for portable use, whereas some units are passive and rely on flow through the sensor.
