What is a Vortex Flow Meter
A vortex flow meter measures fluid flow using the vortex shedding principle.
When fluid flows past a bluff body, vortices are generated at a frequency proportional to the flow velocity.
This technology is widely used for steam, gas, and liquid measurement in industrial systems.
As shown in the vortex flow meter working principle diagram, vortex frequency is proportional to flow velocity.
Vortex Flow Meter Working Principle Diagram
Alternating vortices are generated behind the bluff body, and frequency is proportional to flow velocity.
How It Works
As fluid flows past the shedder bar, alternating vortices are generated downstream.
The sensor detects these vortex frequencies and converts them into flow signals.
This allows measurement of:
• Volumetric flow
• Mass flow (with temperature & pressure compensation)
Why Choose Vortex Flow Meter
✔ No moving parts → maintenance-free
✔ Long-term stability
✔ Suitable for steam, gas, and liquid
✔ High temperature resistance (up to 500°C+)
✔ Reliable in harsh industrial environments
Vibration Immunity
Stable Measurement in High Vibration Conditions
Pipeline vibration can affect measurement accuracy.
HHD vortex flow meters feature:
✔ Advanced digital signal processing (DSP)
✔ Built-in vibration compensation algorithm
✔ Effective filtering of mechanical noise
Ensuring stable measurement even near:
• Pumps
• Compressors
• Heavy industrial equipment
Why It’s Ideal for Steam
Vortex flow meters are the most widely used solution for steam measurement.
✔ Not affected by fluid density changes
✔ Suitable for saturated and superheated steam
✔ Stable long-term performance
Ideal for boiler systems and steam distribution networks.
Saturated vs Superheated Steam
Correct Configuration for Accurate Steam Measurement
Saturated Steam:
✔ Requires temperature compensation
Superheated Steam:
✔ Requires pressure + temperature compensation
Without proper compensation, errors can reach up to 15%.

Multivariable Vortex Solution
Integrated Mass Flow & Energy Measurement
HHD multivariable vortex meters provide:
✔ Temperature + pressure integration
✔ Real-time mass flow calculation
✔ Energy monitoring capability
Benefits:
• Reduced installation complexity
• Improved measurement accuracy
• Fewer leakage points
→ Recommended for energy management systems
Steam Hammer Resistance
Designed for Harsh Steam Environments
Steam systems often experience:
• Thermal shock
• Water hammer
HHD vortex meters feature:
✔ Forged stainless steel sensor
✔ Solid shedder bar design
✔ No internal seals or wear parts
Ensuring long-term durability in demanding conditions.
As shown in the temperature and pressure compensation installation, accurate steam measurement requires proper configuration.
