Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Real-Time Fluid Monitoring: Measures flow rate (L/h), accumulated total flow (L), temperature (°C), and pressure (kPa) with 0.5% accuracy for air, gas, water, oil, and liquid mediums.
  • Multi-Protocol Communication: Supports RS485, 4-20mA, and pulse outputs for seamless integration into industrial or commercial systems via TX/RX ports.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a durable metal-and-plastic hybrid casing, ensure reliable operation in harsh environments exposed to oil, water, and corrosive gases. This design outperforms plastic-only models prone to degradation in industrial settings*.

  • 2. Multi-Parameter Interactive Design

    • With a high-contrast LCD display and dedicated control buttons, monitor real-time flow rate, total accumulation, temperature, and pressure simultaneously. This intuitive interface simplifies navigation compared to models with limited display functionality*.

  • 3. Precision Performance Parameters

    • With 0.5% accuracy, achieve precise measurements for critical applications like chemical processing or water treatment, surpassing standard meters with ±1% accuracy*. The 4-20mA and RS485 outputs enable seamless integration into automated systems.

  • 4. Versatile Scenario Solutions

    • With total accumulation and temperature/pressure monitoring, streamline inventory management and compliance in commercial or industrial settings. The variable-area design adapts to fluids like air, gas, oil, and water, unlike single-medium devices*.

  • 5. Industrial-Grade Certification Standards

    • With RS485 communication and 24VDC power compatibility, meet global industrial standards for fluid measurement systems. This ensures interoperability with PLCs and SCADA setups, exceeding basic analog-only meters*.

Supplier's note

  1. Technical Breakthroughs:

    • Triple Redundant Alarms (Pro Model): 16 programmable channels ensure fail-safe monitoring in critical infrastructure.
    • Enhanced Accuracy (Pro/Advanced): ±0.2% precision reduces material waste in high-stakes processes like petrochemical refining.
    • Extended Temperature Range (Pro Model): Operates in extreme environments (-40°C to 120°C), ideal for Arctic or high-temperature oil fields.

  2. Version Selection Guide:

    • Base Model: Best for standard applications (e.g., HVAC systems) requiring basic monitoring and RS485 connectivity.
    • Advanced Model: Suited for mid-tier industries (e.g., food processing) needing Modbus compatibility and wider temperature tolerance.
    • Pro Model: Recommended for harsh environments (e.g., offshore drilling) where extreme accuracy, extended temperature ranges, and networked alarms are critical.

    With the Pro version’s ±0.2% accuracy, you can reduce material overconsumption by 15% in precision manufacturing. Its Ethernet support also enables remote diagnostics, cutting downtime by 30% compared to traditional models.

Note: Asterisks () denote specifications exceeding industry benchmarks by 20–30%.
