There are many options when it comes to flow technology. It is, therefore, difficult to find a suitable flowmeter for your application. Before making a decision, you need to consider many factors. The cost is only one factor. Here are some tips to help you select the best product.
1. Take into account your needs
A flow meter is a device that measures the speed at which liquids or gases pass through a pipeline. Even if you buy a primary flow indicator at a local store, it will do the job. This device is simple to set up and does not require any external power.
2. Cost should not be your deciding factor
When buying a flowmeter, ensure you choose a reasonably-priced unit. It is not a wise decision to buy the cheapest unit. The most affordable device may be the best, but it could cause you problems down the line. These devices are made so cheaply that they don’t function properly.
You may prefer to choose a low-cost installation that also includes technical support.
3. Know your Flow
When purchasing a flowmeter, the first thing you should keep in mind is the behavior and liquids that will be passing through it. This is due to the viscosity and flow rate of the fluid.
You can profile the flow of any liquid or gas to quickly determine its behavior. This will allow you to narrow down your options. The profile’s flow will also be different depending on whether it is Newtonian, non-newtonian, or both.
It is hard to predict how non-newtonian fluids such as yogurt, shampoos, or paints will behave.
4. Select the Largest Turndown
Simply put, the turndown is the ratio between the minimum and maximum flow rates as measured by a flowmeter within its accuracy range. You should consider the rejection of the device that you intend to purchase.
You will be able to cover all variations of flow with the device that has the greatest turndown.
5. Take into account the Installation
It is also essential to consider where and how the device was installed. This can impact the efficiency and accuracy of the system. Pipeline obstructions such as bends or valves can lead to distortions that affect repeatability and accuracy. It is best to place the flow meter at the most convenient location for the best results.
It is also essential to follow all installation instructions given by manufacturers, especially if you don’t have much space.
These are some of the best tips for buying a flowmeter. We recommend that you look into reliable manufacturers of magnetic flowmeters like Silver Instruments if you’re looking for a quality magnetic flowmeter.
