Flow meters are devices used in fluid systems to measure linear, nonlinear, volumetric or mass flow rate of a liquid or a gas. They have many different applications and can be fitted with an integrated flow control valve to control output flow. When choosing a flow meter, it is important to consider a range of factors, including the familiarity of plant personnel, their experience with calibration and maintenance, spare parts availability, and average time between failure on site.
There are no standard, ‘off the shelf flow’ meters that are suitable for all applications. Selecting the correct device for your application requires writing a detailed specification that covers the use of the meter, taking into account the features of each meter type. This will help you to narrow down the critical specifications and select a corresponding product. Of course, Charms ’ expert advisers can help with your decision making process.
What are the advantages of flow switches and flow meters?
Flow switches and flow meters are very reliable devices for determining flow rates. A couple of advantages worth mentioning are that they can be used for a number of different applications, including industrial and biomedical to name but a few. Flow switches also offer versatility, economy and accuracy. Some switches can be used to actuate audible or visual alarms, as well as relays or other controls.
Like flow switches, flow meters have a number of advantages in their favour. Firstly, they can give you a true mass flow measurement and very high accuracy readings. They are also unaffected by pressure, temperature and viscosity with self-draining characteristics.
