EIT LiQlyzer Vortex Flow Meter
Simple installation, low maintenance, and high reliability in gas, liquid, and steam flows
Advantages
There are several benefits to using vortex flow meter for flow measurement, such as simple installation without the need for impulse lines, the absence of moving elements that need upkeep or repair, reduced leak probability, and a wide flow turndown range. The extremely low power consumption of vortex metres also makes them suitable for usage for far locations.
Furthermore, Vortex meter are unique in that they can handle applications including liquids, gases, steam, and caustic materials. Additionally resistant to high process pressures and temperatures are vortex flow metres.
Limitations
The majority of the time, vortex meter are not advised for batching or other intermittent flow applications. This is due to the possibility that the batching station's dribble flow rate setting could be below the meter's minimum Reynolds number restriction. The resultant mistake is more likely to be serious the smaller the overall batch is.
Low fluid velocity and low pressure gases do not result in a powerful enough pressure pulse. The meter's K factor will gradually change if the process fluid has a tendency to coat or accumulate on the bluff body, as in sludge and slurry service. For these uses, vortex-shedding flowmeters are not advised.
The vortex meter's accuracy will decrease when monitoring multi-phase flow since it cannot distinguish between the phases. The inner section of the pipe should be kept open at the bottom because the liquid phase is likely to travel on the bottom of the pipe when it is horizontal. The bluff body can be installed horizontally to accomplish this. With strong reproducibility, measurement error in these applications is around 5% of the actual flow.
