Top tips for selecting the right flowmeter for you

At Litre Meter, we want to make sure that you get the most for your money when it comes to buying a flowmeter, so we’ve put together our top tips for selecting the right device for you…

Made to quantify the rate that liquid or gas moves through it, flowmeters are required by test and measurement professionals to provide results in a wide variety of applications where accuracy is critical. This includes measurements for familiar household things like heating, ventilating and air conditioning to aerospace and agriculture.

Type of flowmeter

There are different types of flowmeter to suit different purposes and applications. By simply profiling the gas or liquid it is measuring, it’s possible to discover how it behaves when flowing through a pipe. You can then narrow down the choice of device to best cope with the conditions of the application. If you’re unsure about how to do this, get in touch with a professional and they’ll be able to help.

Purpose

There are a number of different uses for flowmeters, and as we’ve just mentioned, whatever you intend to use it for will affect your range of choice. You must consider temperatures needed, the turndown ratio, whether or not it has to be user-friendly for the workplace, and the type of liquid or gas that it is measuring the rate of. For example, if fluid containing traces of silt or sediment is flowing through the pipeline, we’d suggest that you use an ultrasonic Doppler flowmeter.

Chemical compatibility

It’s really important to take into account the materials involved in the process you intend to carry out with the flowmeter. Some materials are not compatible and this can have an effect on both the fluid or gas quality and the flowmeter’s durability. Check each material separately against a reputable chemical compatibility table, and checking your selection with the manufacturer of the fluid is also a wise idea to avoid any potential problems or issues.

Price

Whilst buying a cheaper device may tempt you by saving you money initially, it could actually end up costing you more in the long run. Don’t let short-term savings sway you and think about it practically; a higher priced flowmeter can be more cost-effective in its quality, its back-up and its durability.

Talking of durability, before purchasing the device, you should find out how long it typically lasts. Ask the supplier about its failure rate or the type of application you need it for. This may have an impact on the price, but by evaluating the total life cost of it, you will most likely find it to be worthwhile.

Installation

It’s also important to think of the installation before selecting your flowmeter. Consider exactly where and how it will be installed as this can hugely affect its accuracy and efficiency. You must think about the type of meter and whether it’s affected by any obstructions in the pipeline like joints, bends or valves as these could cause distortions to the flow.  This is all worth doing because if the device is installed correctly in a suitable application, it will be more accurate and will ultimately save you money.
