How to Select the Right Flow Meter

Considering that there are so many different flow technology options these days, the job of finding the ideal and correct flow meter for a particular application may turn out to be a very difficult one. This likewise is aggravated by the fact that so many different factors are needed to be considered before coming up with the decision. You never should believe when self-proclaimed experts tell you that in selecting a flow meter, it’s really just about the price.

The first thing you need to know is if you’re actually in need of a flow meter. There are several applications in which the equipment is required, but it also does not mean you need them all the time. For instance, you probably might just be looking to know the rate in which gas or liquid is moving inside a pipeline. If it’s the kind of application you intend to do, all you need is a simple flow indicator that likewise can be purchased from your flow meter supplier. Buying the flow indicator is more sensible because it’ll cost a lot less than the basic flow meter.

Next, we strongly discourage you in purchasing the cheapest flow meter you can find out there. We aren’t saying you will be getting a crude, broken, or defective product for a cheap price; it’s just that when you opt to go for the cheapest, never expect it to perform the way you want it and never think it’s going to last long. For the most part, low-priced flow meters don’t come with warranty and technical backup from the supplier.
Where To Start with Systems and More

Meanwhile, before you start looking at your options, you first must particularly know your flow. In this regard, you need to be completely aware that each kind of liquid or gas will have a different behavior when flowing through a pipeline. The difference in behavior is literally caused by a process called viscosity, which is generally defined as the measurement as to how much fluid will resist the flow. The resistance thereby affects the velocity of the flow in the pipeline.
Lessons Learned About Equipment

It is best to purchase a flow meter that comes with the widest turndown. This is a crucial factor to consider since there is no way to figure out in advance the exact range of flows intended to be measured. By selecting a flow meter with a wide turndown, it means you get the guarantee that all anticipated flow variations will be covered.

Finally, choose the flow meter that gives you the best accuracy possible for the specific application. In case you have the lowest uncertainty of measurement, the best option for you is a positive displacement meter. Turbine meters meanwhile are the most ideal option for those applications with the highest short-term repeatability, while electromagnetic types offer best suitability for the widest flow range.
