Overview
The YFVW300A is a wireless vortex flow meter using the Karman vortex street principle combined with industrial wireless protocols (LoRaWAN / NB-IoT) for non-contact flow monitoring of steam, gases and low-viscosity liquids. Battery operation removes the need for cabling in high-temperature or hazardous zones, enabling IoT-based energy management and remote monitoring.

Principle & Key Features

• Measurement principle: Karman vortex street (vortex shedding behind an orifice/obstacle).
• Wireless communication: LoRaWAN and NB-IoT industrial protocols for long-range, low-power telemetry.
• Applicable media: steam, plant gases (compressed air, nitrogen, oxygen), low-viscosity liquids; supports explosion-proof configurations for flammable gases.
• No moving parts and no pressure-sensing tubing: reduces maintenance and extends service life.
• Battery-powered design: enables zero-wiring installation where cabling is impractical or unsafe.

Product Advantages

• Zero-wiring deployment: eliminates cabling costs and complexity in hazardous or high-temperature areas.
• Wide turndown ratio: 10:1 range; steam measurement from 0.5 to 25 m/s for flexible process control.
• Robust environmental performance: operating range -40°C to 350°C and IP67 ingress protection; engineered to resist vibration and outdoor conditions.
• Intelligent self-diagnosis: on-device health checks and automatic temperature/pressure compensation to improve measurement reliability (≈30% improvement reported).
• Cloud integration: direct transmission to energy management platforms with alerting and reporting capabilities.

Core Application Areas

• Steam energy metering: boiler output, steam distribution, heat exchangers and process steam monitoring.
• Industrial gas monitoring: compressed air networks, nitrogen/oxygen lines and plant gas utilities.
• Chemical and process industries: safe metering of flammable gases in explosion-proof installations.
• HVAC and central utilities: refrigerant and steam flow monitoring for energy audits and efficiency programs.
• Distributed piping networks: wireless monitoring of remote pipelines where power or cabling is unavailable.

Pain Point Solver
Solves cable aging and failure in high-temperature steam lines, high installation costs in explosion-proof zones, and power supply challenges in remote locations by providing battery-powered, wireless flow measurement and monitoring.
