Insertion Type Vortex Flow Meter

The working principle is similar to traditional vortex meters. When the fluid flows past a
bluff body attached to the probe, it generates vortices. The frequency of these vortices is
directly proportional to the flow velocity.
Formula
f = (St × V) / d
Where:
 f = Vortex shedding frequency
 St = Strouhal number
 V = Flow velocity
 d = Width of bluff body
The sensor detects these vortices and converts them into electrical signals. The transmitter
processes the signal and calculates:
 Instantaneous flow rate
 Totalized flow
 Temperature & pressure (optional)
 Mass flow (optional)
This makes insertion vortex meters ideal for measuring gas, steam, and liquid flow across a
wide range of industries.
