Overview
The YFVW300C wireless vortex flow meter applies the Kármán vortex street principle with industrial wireless communication (NB‑IoT and LoRaWAN) to perform non‑contact flow measurement of steam, gases and low‑viscosity liquids. With no moving parts and no pressure‑sensing tubing, the device supports battery operation to overcome wiring constraints in high‑temperature and hazardous areas, enabling IIoT data transmission for energy and process monitoring.

Product advantages

• Zero‑wiring deployment: reduces cable and conduit costs (up to ~90% reduction in cable length) and lowers installation complexity and expense in hazardous zones.
• Wide turndown ratio: 10:1 range ratio; steam velocity measurement from ~0.5 to 25 m/s covering startup to full load conditions.
• Robust environmental performance: designed for high temperatures (operating range -40 °C to 350 °C), IP67 ingress protection and resistance to vibration and external interference.
• Intelligent diagnostics: real‑time sensor health monitoring with automatic temperature and pressure compensation to improve measurement reliability.
• Cloud connectivity for energy management: native NB‑IoT / LoRaWAN data transmission to cloud platforms for energy reporting and alarm generation on threshold exceedance.

Core application areas

• Steam energy metering: monitoring boiler steam, heat exchangers and process steam consumption.
• Industrial gas monitoring: flow tracking for compressed air, nitrogen, oxygen and other plant gases.
• Chemical and process control: safe metering of flammable gases (methane, propane) with options for explosion‑proof installation.
• HVAC and refrigeration systems: refrigerant and utility gas flow monitoring for energy audits.
• Distributed piping networks: wireless monitoring for steam/gas pipelines where external power or wiring is impractical.

Pain point solver
Addresses rapid cable aging in high‑temperature steam lines, high wiring costs and complexity in explosion‑proof zones, and power supply challenges for remote or hard‑to‑reach installations.
