If you aren’t sure what a flow meter is, you are not alone. It is simply a device that measures the flow rate of a liquid or gas. There are several applications both at home and professionally where a flowmeter can be used, and there are also different types of meters to choose from. Finding the right meter for the job can be confusing, which is why we have included the following tips in our buying guide.
According to the best flowmeter reviews one of the first aspects to consider is the price. While the cost of the meter will often depend on the type, in most cases deciding on a set spending limit will help you narrow down your possible options. The price of the flow meter will also depend on its included functions and features, which means you can often find a basic model that is designed to fit most budgets.
The materials used in construction will affect its price, along with the quality of the flow meter. Some inexpensive flow meters might seem budget friendly, but if they are made from inferior materials they might not last long enough to be worth their low cost. This can also affect the accuracy of your readings which can result in expensive problems if the flow rate of a liquid is off. In most cases it will be worth it to spend a little extra money on a quality flowmeter.
When it comes to choosing the best flow meter you need to decide on the type. Variable area flow meters are the most common and can be used to measure liquids and gases. These meters are inexpensive, easy to use, and are often recommended for use at home. Spring and piston models are also incredibly simple to use, and are only priced slightly higher than ones that come with a float and tapered tube. There are also inexpensive gas flow meters which are designed to be used in specific applications.
If you are measuring the flow rate of wastewater you will probably want to choose an ultrasonic flow meter. Since you are not placing the meter is the potentially corrosive liquid you don’t have to worry about sensitive components being damaged. It should also be noted that these types of meters are priced a little higher since you are using ultrasonic vibrations to measure the flow rate of the liquid. Other types of flow meters designed for use with water include paddlewheel sensors and positive displacement models. If you are dealing with a straight pipe with gas or water a positive displacement flow meter might be the best choice for you.
If you are looking for an accurate flow meter that can be used with water and gas, you might want to consider a turbine one. In some cases you might need to measure conductive liquids, and a magnetic flow meter will usually provide accurate readings without any problems. You can also find several types of flow meters on the market that are designed to be used for specific applications, but these are generally intended for professional applications.
Once you have decided on the type of flow meter you will want to make sure that it is accurate. If the meter can’t accurately measure the flow rate it will basically be useless. Since there are several types of flow meters that can be used for the same applications, you can usually find one that is accurate and designed for your task. One aspect to consider is whether the flow meter comes with moving parts. Not only are these meters often priced higher than similar models, they also come with certain problems.
Moving parts are more prone to wear and tear, which means they can break without warning. In some cases a small piece can come loose, and you might not realize it until you notice your readings are off. Calibration is also more difficult when there are several moving parts and this will affect the meter’s accuracy. Another problem is that changes in temperature can cause parts of the flow meter to shrink or expand. When this happens parts can come loose, rendering the meter useless until it can be repaired. In most cases experts recommend choosing a flow meter with as few moving parts as possible, unless there is not another option.
If your budget will allow it there are a few features you might want to consider that can make the flow meter easier and more convenient to use. Large dials and digital displays are easier to read, which is always an advantage. Models that come with handy instructional manuals ensure that you know how to properly use the flow meter, and this is important if you want to be able to take accurate readings. You can also find flow meters that double as regulators, which is always a convenient option.
