STLU series vortex flow sensor is a new fluid oscillation type flow sensor based on the principle of Karman vortex, using stress detection method, using piezoelectric crystal as a sensitive component and separating the detecting component from the vortex generator. It can be widely used in process measurement and energy saving management of various gases, liquid, steam and other single-phase fluids in petrochemical, metallurgical machinery, heating and power supply, medical research and other industries. This article lists the advantage and disadvantage of vortex shedding flow meter.
Vortex flow meter advantage
-
The vortex flowmeter has no moving parts, and the measuring component has a simple structure, reliable performance and long service life.
-
The vortex flowmeter has a wide measuring range. The turndown ratio can generally reach 1:10.
-
The volumetric flow rate of the vortex flowmeter is not affected by thermal parameters such as temperature, pressure, density or viscosity of the fluid being measured.
-
It measures the flow of liquids, gases or vapors, has very wide applications
-
It causes little pressure loss.
-
High accuracy, and low maintenance
Vortex flow meter disadvantages
-
It has poor anti-vibration performance. External vibrations can cause measurement errors in the vortex flowmeter and may not even work properly.
-
The high flow velocity shock of the fluid causes vibrations in the vortex body, which reduces the measurement accuracy.
-
Cannot measure dirty media
-
Straight pipe requirements are high when mounting the vortex flow meter
-
Not suitable for low Reynolds number fluids measurements;
-
Low meter factor (compared to turbine flow meter);
-
It is not suitable for the pulsating flow.
