When the fluid passes through a vortex generator composed of spiral blades, it is forced to vigorously rotate around the axis of the generator, forming a vortex. When the fluid enters the diffusion section, the vortex flow is subjected to backflow and begins to undergo secondary rotation, forming a gyroscopic vortex phenomenon. The frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid. The flow rate can be determined by measuring the frequency of secondary rotation and precession of the fluid using the detection element. And it can achieve good linearity over a wide range of flow rates. The flow calculation formula is: K (flowmeter coefficient)=F (vortex frequency)/Q (volumetric flow rate).

Sichuan flowmeter needs to do a good job in process installation:

Although this type of flowmeter does not have many special requirements for process installation and usage environment, any type of flow measuring instrument has a commonality, which is to avoid vibration and high-temperature environment interference components as much as possible, maintain smooth and straight inner walls of the straight pipe section before and after the flow sensor, and ensure that the measured medium is a clean single-phase fluid.

Sichuan flow meters should pay more attention to internal maintenance:

If regular inspection or cleaning of the measuring chamber and its components of the flowmeter is required due to dirty temperament or other reasons, one thing must be particularly noted:

For vortex flowmeters of the same specifications, the core components such as vortex generator and guide body cannot be interchanged. Otherwise, the instrument measurement coefficient must be recalibrated and the temperature and pressure sensors equipped with it must be systematically calibrated.
