Darhor DFG Series Acrylic Inline Flow Meter for Water Rotameter GPM LPM air Flowmeter

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Accurate Fluid Measurement: Measures flow rates of water, air, and gas with ±4% accuracy, displayed in both gallons per minute (GPM) and liters per minute (LPM).
  • Transparent Monitoring: Acrylic/polycarbonate body allows real-time visibility of fluid flow for easy troubleshooting and system optimization.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a corrosion-resistant metal base and transparent acrylic body, ensure durability and clear visibility of fluid flow, outperforming plastic-only models*.

  • 2. Dual-Unit Interactive Design

    • With dual-unit (GPM/LPM) markings, easily monitor flow rates in preferred units without conversion, unlike single-scale meters*.

  • 3. High-Accuracy Performance

    • With ±4% accuracy across water, gas, and air, deliver precise measurements in diverse applications, surpassing lower-precision alternatives*.

  • 4. Versatile Scenario Adaptability

    • With multi-medium compatibility (water, gas, air), adapt to both residential irrigation and industrial processes, outperforming single-application flow meters*.

  • 5. Seamless Inline Installation

    • With an inline design, integrate directly into pipelines without flow disruption, unlike bulky external sensors*.
