What is cavitation in fluids? What impact does it have on vortex flowmeters?
Cavitation phenomenon refers to the decrease in pressure on the downstream side of a swirl vortex flowmeter caused by pressure losses in the fluid; when this pressure drops below the saturated vapor pressure at the liquid’s operating temperature, bubbles are formed. Cavitation can affect the accuracy of instruments, and in severe cases it can even render them unusable. Therefore, special attention should be paid when measuring liquids that are prone to vaporization (such as liquid ammonia) or those operating under conditions close to their critical state. To prevent cavitation, it is necessary to maintain a minimum pressure within the pipeline
