It includes EMI protection to guard against interference from pumps or motors, ensuring reliable readings. The device offers versatile unit options (GAL, QTS, PTS, L) and operates within a flow range of 2.4-26.4 GPM (9-100 LPM) at up to 87 psi, making it suitable for a wide set of fuel and water monitoring tasks. Ideal for applications where moisture exposure is a given.
DAE AS250U-100P 1″ Water Meter with Pulse Output

The DAE AS250U-100P is a 1″ inline water meter designed for city water measuring. It supports vertical or horizontal installation and features an upward-facing dial for easy reading. It is suitable for use with CO-10 or AMR systems for remote monitoring and billing, and is ISO 4064 compliant for accuracy in potable water systems. The meter is not intended for pit applications and can be paired with optional cloud metering solutions for real-time data and alerts on abnormal usage.
GRYVOZE 1 Inch PTFE Waterproof Chemical Flow Meter

This chemical flow meter from GRYVOZE features a PTFE coating for corrosion resistance, making it suitable for weak acids, bases, and mildly corrosive liquids in lab or agricultural settings. Its solid aluminum alloy housing provides durability and impact resistance. The unit is IPX8 waterproof, enabling reliable outdoor operation in wet environments while maintaining accuracy and longevity even in challenging conditions.
GRYVOZE 1 Inch Digital Water and Fuel Flow Meter Kit

This kit includes a 1-inch digital flow meter with two male connectors, designed for water, diesel, gasoline, and other liquids. It features IP68 waterproofing and EMI resistance, ensuring robust performance in wet environments and environments with electrical noise. The meter offers ±1% accuracy and supports multiple measurement units (GAL, QTS, PTS, L, m³), providing flexible data capture for varied applications straight out of the box.
Buying Guide
Key purchase considerations
- Fluid compatibility: Ensure the meter materials (including seals and coatings) are compatible with the liquid you measure. PTFE-coated options excel with corrosive liquids, while standard plastics suit fresh water.
- Waterproofing and environment: Choose IP ratings according to where the meter will operate. IP68 and true waterproof designs best suit outdoor or wet environments; dry-environment meters suit sheltered spaces.
- Accuracy and flow range: Look for meters with ±1% accuracy for reliable readings and ensure the flow range covers your expected maximum flow rate (e.g., 2.4-26.4 GPM or similar).
- Units and display: A digital LCD display with multiple unit options (GAL, QTS, PTS, L, m³) simplifies reporting and data logging across different regions and standards.
- Installation orientation: Some meters support vertical and horizontal installations; confirm compatibility with your piping setup and any required adapters.
- Remote monitoring: If long-term monitoring is needed, consider meters with pulse outputs or cloud-enabled options compatible with AMR/SCADA systems.
Comparison considerations
- Durability: Aluminum housings and EMI protection contribute to longevity in industrial settings; PTFE coatings extend chemical resistance for labs or agri-spraying.
- Maintenance: Water and fuel meters with straightforward LCD readouts reduce maintenance time; consider cleaning guidelines for colorless oils or residue after use.
- Cost vs. value: Higher IP ratings and corrosion-resistant coatings generally justify higher upfront costs in exchange for reduced downtime and longer service life.
