Description

Precision Gas Flow Measurement for Professionals Whether optimizing compressed air systems, monitoring CO₂ in carbonation, or conducting environmental research, this portable Digital Gas Flow Meter Tester combines lab-grade accuracy with industrial durability. Why This Flow Meter Stands Out ？✅ Direct Mass Flow Measurement: Thermal sensor technology calculates mass flow directly, eliminating complex calculations for temperature or pressure changes. Measure exact gas consumption, leak rates, or distribution efficiency. ✅ Ultra-Wide Turndown Ratio (80:1): Detect minute leaks (0.1L/min) or monitor high-capacity flows (250L/min) with one device—no need for multiple meters. ✅ Field-Calibration Flexibility: On-site calibration for uncommon gases (e.g., methane, hydrogen) using a simple menu-driven interface. Save custom K-factors for repeat tasks. Technical Specifications Accuracy: ±1.5% of reading Response Time: <1 second Display: Backlit LCD (instantaneous flow, totalizer, battery status) Outputs: RS485 Modbus, 4–20mA (optional) Threads: G1/4” or 1/4” NPT (custom threads available) Power: 3.6V Li-ion battery or 24V DC Key Applications HVAC/R: Balance gas distribution in heating systems or refrigeration units. Pharmaceuticals: Verify inert gas flows in production lines. Food & Beverage: Optimize CO² injection for consistent carbonation. Environmental: Track landfill emissions or stack gas flow rates. Easy Setup in 3 Steps 1. Connect: Attach to pipelines via G/NPT threads—no adapters needed. 2. Select Gas: Choose from pre-loaded profiles or input a custom K-factor. 3. Monitor: View real-time data on the LCD or export via Modbus. Pro Tips for Peak Performance 1. Zero Calibration: Perform in stable conditions to maximize accuracy. 2. Use Filters: Protect the sensor from moisture or particulates in dirty gas streams. 3. Update Firmware: Download enhancements for new gas profiles or features.
