Steam / Gas Vortex Flow Meter

A Vortex Flow Meter measures flow based on the principle of vortex shedding. When
steam or gas passes around a bluff body, vortices are formed alternately on both sides of the
obstruction. The frequency of these vortices is directly proportional to the flow velocity.
The meter measures this vortex frequency and converts it into volumetric, mass, or energy
flow depending on the requirement.
Why Vortex for Steam & Gas?
Steam and gases often have:
 Rapid pressure fluctuations
 Variable temperature
 High flow velocities
 Contaminants
 Changing density and viscosity
Vortex flow meters are not affected by these variations, making them ideal for industrial gas
and steam measurement.

Working Principle of a Steam / Gas Vortex
Flow Meter
When steam or gas flows past a fixed bluff body inside the flowmeter pipe, alternating
vortices are formed downstream. These vortices generate a frequency proportional to the flow
rate.
Formula:
V = f × K
Where:
V = Flow velocity
f = Vortex frequency
K = Meter constant
A built-in piezoelectric or capacitive sensor detects these vortices and converts them into
electrical pulses. The onboard microprocessor calculates the actual flow rate, applying
temperature and pressure compensation if required.
