Digital vortex flowmeter is made through field test of sensor and shell composition, and use a SSP (spectrum signal processing) function of the digital electronic technology. We have more than twenty ten thousand sets of vortex flowmeter sales performance, and on the basis of the development of the digital vortex flowmeter. Even in harsh conditions, digital vortex flowmeter also has high precision and high stability. Because of reliability, reasonable design, digital vortex flowmeter can improve equipment efficiency, so as to reduce the production cost.
