Vortex flowmeter is according to Carmen (Karman vortex theory research production, mainly for industrial pipeline medium fluid flow measurements, such as liquid, gas, steam and other media. The pressure loss is small, the measuring range is large, the precision is high, and the volume flow of the measuring condition is almost not affected by the parameters such as the density, pressure, temperature and viscosity of the fluid. No moving mechanical parts, high reliability, low maintenance. Instrument parameters can be stable for a long time. Vortex flowmeter with piezoelectric stress sensors, high reliability, can work at -20 to +250 DEG C working temperature range. There are analog standard signal, but also a digital pulse signal output, easy to use with the computer and other digital systems, is a more advanced and ideal measuring instrument.
