Overview
YFVW300D LoRa Wireless Vortex Flow Meter uses the Kármán vortex street principle for non-contact flow measurement of steam, gases and low-viscosity liquids. It integrates industrial wireless communications (LoRaWAN / NB-IoT) and supports battery operation to provide a wireless IIoT energy management solution for high-temperature or hazardous environments.

Key Features

• Non-contact vortex measurement based on the Kármán vortex street (vortex shedding) principle.
• Industrial wireless: native LoRaWAN and NB-IoT support for direct cloud or energy-platform transmission.
• Battery-powered option to avoid wiring in high-temperature or explosion-proof zones.
• No moving parts and no pressure-sensing tubing, reducing maintenance points.

Product Advantages

• Zero-wiring deployment: cuts cable and conduit costs and simplifies installation in hazardous or high-temperature sites.
• High range ratio 10:1, enabling accurate measurement across wide operating conditions (typical steam example: 0.5–25 m/s).
• Environmental robustness: IP67 protection, vibration-resistant design and thermal tolerance for installations from very low to very high temperatures.
• Intelligent self-diagnosis: real-time sensor health monitoring and automatic temperature/pressure compensation to improve data reliability.
• Direct cloud integration for energy management: supports consumption reports and alerting for energy efficiency programs.

Core Application Areas

• Steam energy metering — boilers, heat-exchange systems and process steam monitoring.
• Industrial gas monitoring — compressed air, nitrogen, oxygen and plant gases.
• Chemical process control — metering combustible gases with consideration for explosion-proof requirements.
• HVAC and central refrigeration — refrigerant and steam flow control for energy auditing.
• Distributed piping networks — wireless monitoring of steam/gas pipelines where external power is unavailable.

Pain Point Solver
Eliminates rapid cable aging and high wiring costs in high-temperature or explosion-proof pipelines by removing the need for wired power and signal cabling.
