When it comes to flow technology, you are spoiled for choice. Therefore, it is more difficult to choose the right flowmeter for your desired application. Many factors need to be considered before making a decision. Cost is just one of those factors. Here are some 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 passing through a pipe, you can choose a flow meter. In fact, even if you get a simple flow indicator from a store near you, it will do the job. The good thing is that this device is easy and simple to install and also does not require external power.
2. Cost should not be your deciding factor
When it comes to purchasing a flow meter, make sure you invest in a reasonably priced unit. Going for the cheapest unit is not a good idea. Although the cheapest device will save you a lot of money, it can create a lot of trouble for you in the future. The reason is that these devices are so cheap that they do not work properly.
Ideally, you might want to go for a cost-effective installation that also includes technical support.
3. Know your flow
The main thing to consider when buying a flow meter is the behavior of the gas or liquid that will pass through the pipe. This behavior is due to the viscosity of the liquid flow.
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 options. Also, the flow of the profile is different depending on whether it is 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 coverage
In simple words, turndown refers to the ratio of the minimum and maximum flow rates 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 has the widest coverage range, it will be able to cover all anticipated flow variations.
5. Consider the installation
Lastly, it is important to consider the location and installation method of the device as it can affect accuracy and efficiency. If there are obstructions in the pipeline such as valves, elbows and unions they can cause distortion and affect the repeatability and accuracy of the flowmeter. For best results, it is a good idea to install the flow meter in the best location.
Also, it is important to follow the installation recommendations given by the manufacturers during the installation, especially when you do not have a lot of space for the installation.
