GRYVOZE Waterproof 1 Inch Flow Meter
The 1 Inch GRYVOZE flow meter is fully waterproof and designed for wet environments, delivering accurate readings in demanding conditions. EMI protection helps prevent false readings caused by nearby pumps or motors, ensuring reliable measurements in EMI-rich settings.
It supports multiple units, including GAL, QTS, PTS, and L, making it flexible for different measurement needs. The device works within a flow range of 2.4-26.4 GPM and a working pressure up to 87 psi, suitable for gasoline, diesel, water, and other liquids.
GRYVOZE Waterproof 2 Inch Flow Meter
This 2 Inch flow meter is IPX8 waterproof and outdoor ready, housed in a sealed aluminum alloy shell for durability in wet environments. It offers ±1% accuracy for reliable measurements of water, diesel, fuel oil, and similar liquids, with flexible unit selection for various reporting needs.
Battery life is optimized with an LCD that auto-off after 10 minutes, extending standby to about a year. A low-battery alert helps ensure timely replacement without removing the meter from the pipeline.
GRYVOZE Waterproof 3/4 Inch Digital Flow Meter
Engineered for accuracy in wet environments, this 3/4 Inch digital flow meter features EMI protection to prevent interference from nearby equipment. It provides convenient unit switching among GAL, QTS, PTS, and L, with a flow range of 1-13 GPM (4-50 LPM) and a working pressure of 87 psi.
The waterproof design makes it suitable for diesel, water, gasoline, kerosene, and other liquids. The EMI shielding helps maintain signal integrity in EMI-prone facilities.
GRYVOZE 3/4 Inch Digital Turbine Flow Meter
This 3/4 Inch digital turbine meter is designed with EMI protection to shield readings from external interference. It supports multiple units including GAL, QTS, PTS, L, and m³, and notes an upgraded design to better fit pipe threads for a cleaner seal. It’s suitable for water, diesel, gas oil, gasoline, and other liquids.
Users should ensure proper sealing with PTFE tape and avoid exposure to submersion where not specified. The device emphasizes reliable performance in EMI-rich environments while maintaining measurement flexibility.
GRYVOZE 1 Inch PP Digital Turbine Flow Meter
This 1 Inch PP turbine meter is fully waterproof and designed for challenging liquids like urea, chemicals, acids, and alkaline solutions, along with fuels. EMI protection helps ensure readings remain accurate amid nearby electrical activity.
It offers versatile unit options (GAL, QTS, PTS, L, and m³) and a flow range of 2.4-26.4 GPM (9-100 LPM) at up to 87 psi. The waterproof construction supports use in damp or submerged environments where needed.
Profax Gas Flow Meter – PX 50020
Profax PX 50020 measures shield gas flow rates up to 25 LPM (52 CFH) for applications such as welding where precise gas delivery affects weld quality. The feature set focuses on shielding gas monitoring rather than EMI protection, offering a specialized utility in controlled environments.
Buying Guide: Key Purchase Considerations
- EMI Protection: Prioritize meters with EMI shielding if your facility has nearby motors, pumps, or high-frequency equipment. EMI features help maintain accuracy in noisy electrical environments.
- Liquid Compatibility: Verify the liquid types (water, fuels, fuels blends, solvents) and whether the meter’s wetted materials resist corrosion or chemical attack.
- Waterproof and Outdoor Durability: For outdoor or wet-area deployments, look for IP ratings, sealed housings, and corrosion-resistant casings to extend life.
- Measurement Range and Pressure: Ensure the flow range matches your process. Check working pressure to avoid undersizing the meter for high-flow applications.
- Unit Flexibility: A broad set of units (GAL, QTS, PTS, L, m³) simplifies reporting across different platforms and operators.
- Installation and Sealing: Consider thread types (NPT) and the need for extra sealing materials like PTFE tape to prevent leaks and ensure a clean installation.
- Power and Maintenance: Look for battery life indicators, auto-off features, and easy maintenance access to minimize downtime.
- Not All Models Are Equal: Some meters are designed for water or general liquids, while others are tailored for fuels or chemicals; align with your primary use case.
- Documentation and Support: Check warranty terms and the availability of replacement parts or service support in the United States.
In EMI-prone environments, selecting meters with robust shielding and proper installation practices is essential. Understanding the chemical compatibility, installation requirements, and unit options will help ensure long-term reliability and accurate flow data across diverse applications.
