How to Choose the Right Flow Meter – 6 Tips

Having choices is a good thing but it can be rather overwhelming if there are a plethora of choices in front of you. Choosing the right flow meter is critical for efficient business processes and operations. Flow meters are used by test and measurement professionals to provide results in a wide variety of applications in cases where accuracy is essential. It may include measurements for familiar household things or even those in aerospace and agriculture.

Therefore, it is critical to consider some basic things before you choose the flow meter for your business operations. Besides choosing the right flow meter, you must remember that flow meter calibration is vital. Without calibration, you can’t be assured of accurate results even if you have the best flow meter in your facility.

First, let us look at the 6 different things you need to consider before choosing a flow meter:

1. Type

There are different types of flow meters such as a liquid flow meter or gas flow meter. Understand your needs and choose the one that will suit your unique purpose and applications. Consider the property of the fluid that would pass through the flow meter. If you profile the gas or liquid that the flow meter would have to measure, you will be able to discover how it would behave when flowing through a pipe. Following this, you can narrow down the choice of devices that would cope with the conditions of the applications. If you are unsure of doing this, take the assistance of professionals or lab calibration services who can help you pick and calibrate the right flow meter.

2. Use

Flow meters can be used for a number of uses, which is why you must understand the purpose you need it to fulfill. Consider the temperatures that are needed, its turndown ratio, type of liquid or gas that is measuring the rate of and how user-friendly it is. For instance, if the fluid you would be using contains traces of sediment while flowing through the pipeline, use an ultrasonic Doppler flow meter.

3. Chemical Compatibility

Ensure that the material of the flow meter is compatible with the chemical properties of the fluid or gas that would be used through the flow meter. Some materials would not be compatible, which could have an effect on the quality of the fluid as well as the durability of the flow meter. Test each material separately against a reputable chemical compatibility table and check your selection with the manufacturer of the fluid to avoid any potential problems.

 4. Price

The price of the flow meter usually plays a huge role in determining your purchase choices. While opting for a cheaper device might seem tempting initially to save money, it would end up being far more expensive further on down the line. Focusing on short-term savings isn’t always a good idea as a cheaper flow meter won’t assure quality or durability. On the contrary, a higher priced flow meter will be more cost-effective in the long run. Moreover, it will rank higher on quality, durability and its back-up.

 5. Durability

Ensure that the flow meter you are purchasing has a long life. Find out how long it would typically last and ask the supplier about its failure rate regarding the type of application you need it for. Evaluating the total life cost and longevity of the flow meter may have an impact on the price, however, it would be worth it.

 6. Installation

Consider the installation of the flow meter before buying it. Check exactly where and how it will be installed as it can significantly affect the efficiency and accuracy of the flow meter. Think about the type of meters and if would be affected by any obstructions in the pipeline such as any kind of joints, bends or valves that could cause disturbances in the flow. Installing the device correctly in a suitable application will ensure more accurate results as well as save you money.

While these points may help you make your flow meter selection process easy, it may not be something that you can do on your own. You need a professional on your team to help you choose the right one and explain how to calibrate the instrument.
