7 Steps to Selecting the Proper Flow Meter

how to select the proper flow meterFlow meters help to ensure the proper function of a variety of industrial machinery. Just as the machines vary, so do their flow needs, therefore they may benefit from different types of flow meters. To determine the proper flow meter for your needs, it may be helpful to follow these seven steps.

  1. Determine Necessity

It is important that you know the rate at which the liquid or gas that you are measuring is supposed to move through the machinery. This will help you determine which proper flow meter tool you need.

  1. Focus on Value

When a flow meter tool is offered at reduced rates, it is possible that the lower price was achieved by reducing or cutting out supplier support or using sub-par materials. In such cases, the upfront cost cut could lead to more expensive problems in the future. Therefore, it is best to focus on value rather than low costs.

  1. Know the Flow

Knowing the behavior of the liquid that will be moving through the machinery is critical in determining how it will flow, and in turn, discovering what flow meter is best to use. The different fluids can be broken down into a couple fluid types:

  • Newtonian: water, milk, mineral oils and sugar solutions
  • Non-Newtonian: yogurt, shampoos and paints

Newtonian fluids tend to stick to the walls of the machine, which can cause the flow to slow down and therefore require certain amounts of pressure to reach a particular level of flow. On the other hand, Non-Newtonian fluids vary depending upon how the fluid resists flow. Understanding these factors can help to determine the proper flow meter to promote proper flow.

  1. Choose the Widest Turndown

Turndown can be defined as the flow rate maximum and minimum ratio that a flow meter measures within a given accuracy range. Seeing as there is no way to fully determine the exact range of flow that will be measured, it can be helpful to select a flow meter with a large measuring range.

  1. Consider Installation

Where the flow meter is positioned plays an important part in it producing an accurate reading. For instance, bends, valves or joints in the pipeline can alter flow, which can create an inaccurate reading. That is why it is best for the flow meter, no matter what type it is, to be placed on one of the straight-lengths of the pipeline.

  1. Measure Accuracy

Different flow meters are most efficient in measuring certain types of flow. For instance, turbine flow meters tend to be the best choice for the highest short-term repeatability. By understanding which meter calculates your desired flow rate, you can select the best flow meter for your needs.

  1. Utilize One Reputable Provider

Identifying and using one reputable provider can help to ensure that your systems are compatible and maintain functionality. By using the same provider, you will be able to entrust your flow meter maintenance and possibly calibration to one source, which can help to maintain certain standards.

As you consider your flow meter options, be sure to follow the aforementioned steps to discover the best flow meter for your needs. Whether you select a turbine flow meter, variable area flow meter or some other type, it can be helpful to consult with a knowledgeable professional to ensure that you are on the right trail.
