Overview
The YFVW300D is a NB‑IoT / LoRaWAN wireless vortex (Kármán vortex street) flow meter for non‑contact monitoring of steam, gases and low‑viscosity liquids. Designed without moving parts and without pressure‑sensing tubing, it supports battery operation to avoid cabling in high‑temperature or hazardous areas and enables direct integration with industrial IoT platforms for energy management.

Product advantages

• Eliminates extensive wiring: enables installations in hazardous or high‑temperature zones without conduit runs or long cable routes.
• Wide turndown: 10:1 range ratio, covering conditions from start‑up to full load (steam example: 0.5–25 m/s).
• High environmental tolerance: temperature capability from -40°C to 350°C and IP67 protection; mechanical design resists vibration for outdoor and tunnel installations.
• Onboard diagnostics: real‑time sensor health checks with automatic temperature and pressure compensation to stabilize measurements.
• Cloud integration: direct transmission to energy management platforms via LoRaWAN or NB‑IoT, supporting consumption reports and alert notifications.

Core application areas

• Steam energy metering: monitoring boiler steam, heat exchangers and process steam networks.
• Industrial gas monitoring: flow measurement for compressed air, nitrogen, oxygen and plant gases.
• Chemical and process plants: safe measurement of flammable gases where explosion protection is required.
• HVAC and refrigeration systems: refrigerant and process fluid monitoring for energy audits.
• Distributed piping networks: wireless monitoring of steam/gas pipelines with operation possible without external power supply.

Pain point solver
Solves cable ageing and failure in high‑temperature steam lines, high wiring costs in explosion‑protected zones, and the difficulty of powering remote monitoring points.
