The  vortex  flowmeter  is  a volumetric flowmeter  that measures the volumetric flow of gases, 
vapors,  or liquids,  nominal  volume flow,  or  mass flow produced according to the Karman vortex street principle. It is mainly used for the flow measurement of medium fluids in industrial pipelines, such as gas, liquid, steam and other media.
 It  is  characterized  by  low  pressure  loss,  large measuring range, high accuracy, and almost  no 
influence  of   parameters  such  as    fluid  density,  pressure,  temperature,  and viscosity when measuring volume flow. No moving mechanical parts, so high reliability and low  maintenance.  Instrument  parameters  can  be  stable  over  a  long  period of time. The vortex  flowmeter  uses  a  piezo-electric  stress  sensor,  which  has high reliability and can work  in  the  operating  temperature  range  of  -20°C  to +250°C. There are analog standard signals  and  digital  pulse  signals  output.  It  is  easy  to  use  with  digital systems such as computers. It is a relatively advanced and ideal measuring instrument. 
Vortex flow meter product features:
The  structure  is  simple  and  strong,  no  moving  parts, high reliability, and long-term operation is very reliable.
    The installation is simple and maintenance is very convenient.
    The  detection sensor does not directly contact the measured medium, and has stable performance and long service life.
    The output is a pulse signal proportional to the flow rate, zero drift, and high accuracy.
    Wide measuring range, up to 1:10 ratio.
    Less pressure loss, lower operating costs, more energy-saving significance.
