Overview
The YFVW300C wireless vortex flow meter uses the Kármán vortex street principle combined with industrial wireless communication (LoRaWAN / NB‑IoT) to provide non-contact flow monitoring for steam, gases and low‑viscosity liquids. Battery-powered design and absence of moving parts make it suitable for high‑temperature and hazardous locations and for distributed IIoT energy‑management deployments.

Key Functional Description

• Measurement principle: Kármán vortex street (vortex shedding) using a vortex‑generating element to detect alternating vortices induced by fluid flow.
• Communication: Industrial wireless protocols (LoRaWAN, NB‑IoT) for direct transmission to cloud or energy‑management platforms.
• Power: Battery option eliminates the need for wired power in remote or hazardous locations.
• Measured media: Steam, industrial gases (compressed air, nitrogen, oxygen), flammable gases (methane, propane) and low‑viscosity liquids.
• Design: No moving parts and no pressure‑sensing tubing, reducing mechanical maintenance and tubing failure modes.

Product Advantages

• Reduced wiring and installation complexity: minimises cable and conduit requirements in high‑temperature and explosion‑risk zones.
• Wide measurement range: typical range ratio 10:1; example steam coverage 0.5–25 m/s.
• Environmental robustness: design range −40°C to 350°C; ingress protection IP67 and resistance to vibration interference for outdoor or tunnel installations.
• Diagnostic features: real‑time sensor health monitoring and automatic compensation for temperature/pressure variations to improve data reliability.
• Cloud integration: direct data feeds to energy‑management systems, automated consumption reports and threshold alerts (platform supports email/WeChat alerts where integrated).
• Cost‑effective IIoT deployment: simplifies metering in distributed piping networks and hazardous areas by avoiding complex wiring.

Core Application Areas

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

Pain Points Addressed

• Eliminates rapid cable ageing and high wiring costs in high‑temperature steam pipelines and explosion‑risk zones.
• Enables reliable metering in remote locations lacking power or where wiring increases safety and cost issues.
