Vortex flow meter
vortex flow meter with RS 485 or HART protocol is based on Carmen (Karman) vortex principle,
it can measure the gas, steam or volume flow rate of the liquid, volume flow of standard conditions
or mass flow .Also it can be applied as a flow transmitter for automation and control systems.
