Overview
The YFVW300A Wireless Vortex Flow Meter applies the Kármán vortex street principle with industrial wireless communication (LoRaWAN / NB‑IoT) to provide non-contact flow measurement for steam, gases and low‑viscosity liquids. Its no-moving-parts design and support for battery operation enable deployment in high-temperature and hazardous zones, offering a wireless IIoT solution for energy and process monitoring.

Key features / Advantages

• Zero-wiring deployment: eliminates extensive cabling and conduit costs.
• Wide range ratio: 10:1 range ratio; steam measurement 0.5–25 m/s to cover startup through full load.
• High environmental adaptability: designed for operation/installation temperatures from -40°C to 350°C; IP67 protection; vibration-resistant for outdoor and tunnel installations.
• Intelligent self-diagnosis: real-time sensor health monitoring with automatic temperature and pressure compensation; improves data reliability (~30% reported).
• Battery-powered with wireless connectivity (LoRaWAN / NB‑IoT) to overcome wiring constraints in high-temperature or explosion-proof areas.
• Cloud integration: direct data transmission to energy management platforms, with energy reporting and threshold alerting.

Core application areas

• Steam energy metering: monitoring boiler steam delivery, heat-exchange circuits and process steam lines.
• Industrial gas monitoring: flow tracking for compressed air, nitrogen, oxygen and other plant gases.
• Chemical process control: safe metering of flammable gases (methane, propane) with consideration for explosion-proof installations.
• HVAC systems: refrigerant and steam flow control for central air-conditioning and energy audits.
• Distributed piping networks: wireless monitoring of steam/gas pipelines where external power is unavailable.

Pain point solved
Eliminates rapid cable aging and frequent maintenance in high-temperature steam lines, reduces wiring costs in explosion-proof zones, and resolves power supply challenges at remote measurement points by enabling battery-powered wireless monitoring.
