In the saturated steam measurement using VA-type piezoelectric vortex flow transmitter, vortex flowmeter as a wide range, therefore, in practice, the general consideration of the measurement of saturated steam flow rate shall not be less than vortex flowmeter Lower limit, that must meet the fluid flow rate of not less than 5m / s. According to the size of the steam use of different diameter vortex flow transmitter, rather than the existing process pipe diameter to choose the transmitter diameter.
