Low cost vortex flowmeter
Low cost liquid gas vortex flowmeter supplier
Vortex flow meter has little pressure loss, broad span range and high accuracy. It is not under influence of density, pressure, temperature and viscocity when measuring volumetric flow. It has no movable mechanical parts with high reliability and little maintenance.
