The basic principle of HWFC1 intelligent industrial vortex street flowmeter is the Karman vortex street phenomenon, when the medium flows through the triangular column type vortex generating body at a certain speed, it forms two rows of alternating vortices on both sides, which is called the Karman vortex street. On the basis of Karman vortex street theory, Strouhal proposed that the frequency of Karman vortex street is proportional to the flow rate of the fluid, and through the cable to the converter through intelligent processing, to realize the instantaneous flow of fluid, accumulated flow display and communication between the flow data and the control system. ● Can measure the volume flow and mass flow of steam, gas and liquid. ● The amplifier can be separated from the sensor (separation distance 15m). ● Small pressure loss, wide range, range up to 10-40 times no machinery ● Moving parts, long-term stability, simple structure easy to install and maintain. ● Measured medium temperature up to +350℃ ● Sensor output pulse frequency, its frequency and the actual flow of the measured body is linear, zero drift, performance is very stable ● widely used in measuring superheated steam, saturated steam, compressed air and general gas and liquid volume flow and mass flow
