The vortex street flowmeter is a kind of volume flowmeter to measure the volume flow of gas, steam or liquid, volume flow and mass flow in standard conditions based on Karman vortex  principle, and it can be used in the automation control system as flow transducer.
Feature
 
No moving parts, long-term stability, simple structure, easy to install and maintain.
Sensor in pulse signal output, linear between its frequency and actual flow rate of medium, without zero-shift, high stable performance.
High accuracy, generally liquid's accuracy is ±1.0%, the gas' accuracy is ±1.5%
Wide measuring range, up to 1:20 under Reynolds number 2 x 104~7 x 106;
Small loss pressure is (about 1/4 to 1/2 of orifice meter), belongs to the energy saving flow meter.
Adopts circuit in eliminating interference, with some environmental vibration resistance performance
Using super-low power consumption microprocessor technology, 1 group 3.6 V10AH lithium batteries can be used more than 5 years.
Can be non-linear modification by software to improve the measuring accuracy
Flow totalize with power-off protection by EEPROM more than 10 years
