5 Tips to Help You Choose a Flowmeter

When it comes to flow technology, you have a lot of options to choose from. Therefore it is harder to choose the right flow meter for your desired application. You need to consider a lot of factors before making a choice. Cost is just one of those factors. Given below are few tips that can help you choose the best product.

1. Consider your Needs

If you want to know the speed of a liquid or gas that is passing through a pipeline, you can choose a flow meter. In fact, even if you get a simple flow indicator from a nearby store, it will get the job done. The good thing is that this device is easy and simple to install and doesn’t require external power either.

2. Cost should not be your deciding factor

As far as buying a flow meter is concerned, make sure you invest in a reasonably priced unit. Opting for the cheapest unit is not a good idea. Although the cheapest device will save you a lot of money, it may create a lot of problems for you down the road. The reason is that these devices are so cheaply made that they won’t work properly.

Ideally, you may want to opt for a cost-effective installation that will come with technical support as well.

3. Know Your Flow

The primary thing that you want to keep in mind when purchasing a flow meter is the behavior of the gas or liquid that will pass through the pipeline. This behavior is due to the viscosity of the flow of liquid.

If you profile the flow of a gas or liquid, you can easily find out how it behaves. This will help you narrow down your choices. Also, the flow of the profile is different based on its being Newtonian or non-newtonian.

In the case of non-newtonian fluids like yogurt, shampoos, and paints, it is difficult to predict the behavior.

4. Choose the Widest Turndown

In simple words, turndown refers to the ratio of the minimum and maximum rates of flow measured by a flow meter within its range of accuracy. It is important to consider the turn down of the device you are going to buy.

Choose a device that features the widest turndown, you will be able to cover all of the anticipated variations of flow.

5. Consider The Installation

Lastly, it is important to consider the installation location and method of the device as it can have an impact on the accuracy and efficiency. If there are obstructions in the pipeline like valves, bends and joints can cause distortions and affect the repeatability and accuracy of the flow metre. For the best results, it is a good idea to install the flow meter in the best location.

Besides, it is important to follow the installation recommendations given by the manufacturers during the installation especially when you don’t have a lot of space for installation.
