[0023] It should be noted that the steam flow meter 2 is specifically a VLC-2 vortex flow meter, and the working principle is as follows: the VLC-2 vortex flow meter is an instrument for measuring the flow of matter based on the change of turbine speed, which uses the principle that the rotation speed of the turbine rotor passing through the measured medium is proportional to the flow to carry out measurement. When the medium flows through the vortex flow meter, the kinetic energy of the fluid will drive the vortex meter rotor to rotate, and the measurement resistance exerted by the rotor on the fluid will form a stable vortex frequency signal. The vortex flow meter needs to detect the change of this frequency signal to calculate the flow of the fluid, and the VLC-2 vortex flow meter can be provided with power supply and controlled to be opened and closed by an external device.
