Its advantages are low pressure loss, wide range of measuring range, high precision and no influence from fluid density, pressure, temp and viscosity. No movable mechanical parts are needed, so the reliability is high and the maintenance amount is small. The instrument parameters can be stable for a long time. The vortex flowmeter adopts a piezoelectric stress sensor, has high reliability and can work within the working temperature range of-20 ℃ to +250 ℃. The analog standard signal and the digital pulse signal are output, so that the digital pulse signal measuring instrument is easily matched with a computer and other digital systems, and is an advanced and ideal measuring instrument.

The vortex street flowmeter consists of vortex generating body in flow field, detecting probe, corresponding electronic circuit, etc. When fluid flows through the vortex generating body, two rows of alternately-changed vortices are formed on two sides of the vortex generating body, and the vortices are called karman vortex streets. However, the existing vortex shedding flowmeter still has some defects, such as vibration is a great rival of the meter. In use, attention should be paid to mechanical vibrations, especially transverse vibrations of the pipe (vibrations perpendicular to the pipe axis and to the vortex generator axis), which cause the flowmeter to measure inaccurately with errors.
