Its clear digital LCD displays real-time flow rates and totals, making it practical for monitoring fuel consumption and inventory. Note that this unit is designed for sheltered environments and should be kept dry to maintain performance. The device features a single count range of 99,999 and a total cumulative count of 29,999,999 for long-term tracking.
GRYVOZE Waterproof 1.5 Inch Digital Diesel Flow Meter
This 1.5-inch diesel flow meter offers full waterproofing for durability in wet environments and EMI protection to minimize interference from pumps or motors. It supports multiple units, including gallons, quarts, pints, and liters, enabling flexible reporting. The flow range spans 10.5 to 74 GMP (40–280 LPM), with a working pressure around 87 psi, making it suitable for robust diesel and fuel transfer tasks in challenging conditions.
GRYVOZE Waterproof 1 Inch Digital Water & Fuel Flow Meter
This 1-inch waterproof meter delivers reliable readings in wet settings and includes EMI protection to prevent false results from nearby equipment. It provides versatile unit options (GAl, QTS, PTS, L) and operates within a 2.4–26.4 GPM range, suitable for monitoring gasoline, diesel, water, and related liquids. Its waterproof design suits installations where moisture is unavoidable, while maintaining precision and accuracy.
GRYVOZE 2 Inch Digital Turbine Flow Meter
The 2-inch GRYVOZE meter is designed for higher flow rates with an accuracy of ±1% and an LCD display for real-time readings and totals. It supports various liquids including water and multiple fuels, and is intended for sheltered installations where rain or splashes are avoided. The unit emphasizes durable construction and precise measurement across larger pipelines, making it apt for fleet fueling and industrial uses.
UwinVwin 1″ 2.6-26 GPM Inline Flow Meter
The UwinVwin meter delivers precise measurements with an accuracy of up to ±1% and features a digital LCD that displays real-time flow, cumulative totals, and instantaneous flow. It includes adapters to fit 3/4-inch connections, enabling flexible installation in compact diesel and fuel transfer setups. A caution notes slight factory oil odor during handling, which dissipates with rinsing and proper use for water measurements.
GRYVOZE 3/4 Inch Digital Turbine Fuel Flow Meter
The 3/4 inch GRYVOZE flow meter features EMI protection and an upgraded internal design for full-thread compatibility and tight-seal installation. It operates in a 0.8–13.2 GPM range and is suitable for measuring a variety of liquids including diesel, gas oil, gasoline, and kerosene in sheltered setups. Note that it is not waterproof, so it should not be exposed to rain or immersion, but it provides reliable accuracy in controlled environments.
TEANTECH Turbine Flow Meter 3/4″
The TEANTECH turbine flow meter is compact and portable, featuring a 3/4 inch NPT counter and a digital LCD display that shows instantaneous and cumulative flow. With a maximum working pressure of 20 bar and a wide temperature range, it is suitable for diesel, kerosene, and other light fuels. Its modular design allows easy integration with output modules and remote transmitters for expanded measurement setups.
Buying Guide: Key Purchase Considerations
- Measured liquids and compatibility: Verify that the meter is rated for the fuels you use (diesel, gas oil, gasoline, kerosene) and any additives or contaminants common to your system.
- Accuracy and range: Look for meters with ±1% accuracy and a flow range that covers your typical operating flow. For larger pipelines, a 2-inch or larger meter may be more appropriate.
- Environmental suitability: If your installation is exposed to moisture or rain, choose waterproof models. For sheltered locations, dry-environment meters may suffice.
- Protection against interference: EMI protection minimizes false readings near pumps or motors, which is valuable in busy facilities.
- Units and display: Ensure the meter supports your preferred units (GAL, QTS, PTS, L) and has a clear LCD display for easy monitoring.
- Installation considerations: Check thread size (NPT), included adapters, and whether the device is designed for horizontal or vertical orientation. Some devices require PTFE tape or additional sealing to prevent leaks.
- Maintenance and odor considerations: Factory testing fluids may leave a temporary odor; plan for a rinse before initial use if measuring water to avoid residue.
- Not waterproof vs. waterproof trade-offs: Choose based on location—wet environments benefit from waterproof models, while dry environments can leverage more compact designs with EMI protection.
Selecting the right fuel flow meter involves balancing environmental conditions, required accuracy, and system integration capabilities. Consider the largest flow rate you handle, the liquids involved, and any EMI or sealing demands. If you require portability or modularity, look for meters with adaptable connections and a readable LCD display. For installations near water or rain-prone areas, waterproof models provide durability and consistent readings. Always validate the device’s certification and installation guidelines to ensure safe and compliant operation in your facility.
