Product Description
Compressed Air Steam Vortex Flow Meter 4-20mA RS485 Modbus and Hart
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 .Alsoit can be applied as a flow transmitter for automation and control systems.
