Vortex flow meters generates vortexes (Von Karman Swirls) using triangular prism and measures the frequency of vortexes which is proportional to fluid flow rate Quick look at Nagman’s Vortex Flow Meters
Custody transfer of natural gas metering
General water applications
Steam measurement
Liquid chemicals & pharmaceuticals
No moving parts, and the measuring component has a simple structure, reliable performance and long service life.
The turndown ratio can generally reach 1:10.
Wide measuring range.
Not affected by thermal parameters such as temperature, pressure, density or viscosity of the fluid being measured
Causes little pressure loss.
High accuracy, and low maintenance.
