For industrial site commonly used piezoelectric vortex flow sensors, vortex detection position has a direct impact on the signal measurement vortex, adjust the position of the probe can be detected if a stronger signal that measurement limit can be reduced. Be careful when installing the sensor to be careful, because it is very sensitive, when installed in the field to avoid man-made damage, affecting its normal use. Vortex vortex flow sensors shedder is varied, often used within the vortex tube body is a cylinder, in addition to the above-mentioned trapezoidal body, as well as cylindrical, triangular prism, T-shaped columns, rectangular columns occur. May also be used to modify the shape of cylindrical or deformed, or five cylindrical shape is combined with another.
