How We Chose The Best Water Flow Meters

Water flow meters are fairly simplistic, but they serve an important purpose. When it came to choosing the best models, we chose carefully. In our search, we chose to focus on these three elements: accuracy, quality materials, and ease of use.


The most important feature of any water flow meter is accuracy. There is no sense in purchasing a measuring device that doesn’t measure properly. That is why we looked for meters that were well-calibrated and designed to measure as little as 1/10 gallon, some measuring as little as 1/10 liter. With any of the meters on our list, you can rest assured that your usage measurements will be spot on.

Quality Materials

The second most important feature of a water flow meter is quality, especially when it comes to permanent meters such as the DIGITEN Flow Meter. Since the majority of flow meters are meant to be used outdoors and in wet conditions, they have to be built to last. The last thing you want is to go through the effort of installing a flow meter only to be forced to replace it every couple of years. That is why we chose meters that were made with quality materials and designed to last through years of daily use.

Ease of Use

Last, but not least, we looked for meters that were easy to install and even easier to use. We understand that not everyone who needs a water flow meter is a master plumber. That is why we chose to feature a variety of options so that no matter how limited or advanced your plumbing skills are, there is an option here for you.

What You Need To Know About Water Flow Meters

If you’re just beginning your research into water flow meters, you may be surprised by their wide range of applications. Here is a quick rundown of just a few of the many ways that you can use these meters to save water and, hopefully, save a little money on your next water bill.


When you think of water flow meters, you may only think of the ones used to measure household water usage, but they can be used for so much more. You can use one of these meters to ensure your sprinkler system isn’t leaking or overwatering your lawn. Monitor the amount of water you put in your pool. Or easily keep track of the water levels in your RV water tanks. Some cities will give you a discount on your sewer bill if you can prove how much of your water usage goes into lawn care. How do you prove that? With a water flow meter.

If you own rental property, you can use a water flow meter with remote monitoring to keep tabs on how much water your renters are using as well as receive early alerts about any possible plumbing issues such as a leak or burst pipe. This is also a helpful feature for those who are away from home for long periods. A meter like the Flume Water Monitor can alert you as soon as a leak is detected, giving you the chance to deal with it right when it happens instead of coming home to a flood.

In many areas, careful water monitoring is important, both for your budget and for the environment. Water flow meters make it easier for you to know exactly how much water you’re using, so you can adjust accordingly when necessary.

Clean Water Only

Some people use water flow meters for liquids other than clean water such as certain types of fuel or gray water. If you need a flow meter for something other than clean water, be sure to read the product specifications very carefully before making your purchase. Many of these meters are designed specifically for clean water only and are not able to withstand corrosive substances. They may give inaccurate readings or breakdown completely from misuse.

High-Pressure Situations

If you’re using your water flow meter for something on a larger scale, such as a large irrigation system, you should be aware that some water flow meters can decrease water pressure. This is not typically an issue in regular household use because the average residential water pressure is already low enough that it isn’t hampered by a regular flow meter. This is simply something to keep in mind if you’re dealing with high water pressure on a grand scale.

How to Choose The Best Water Flow Meter For You

If you’re reading this article, you may already have a basic idea of what type of meter you need, but just in case, here’s some advice that may help you feel more confident in your decision.

Substance Over Style

Remember that the most important things to look for are accuracy and quality. Extra features may seem great, but they won’t help you if the meter doesn’t last. With that in mind, look for a brand that is reliable and built to last, then choose the model that fits your needs.

Know Your Flow

To determine what your needs are, you have to start with the basics such as knowing why you need a water meter. All water flow meters may have the same basic function, but they do not all function in the same way. Different situations require different types of meters, some being more specific than others.

Do you need to monitor water usage for your entire household? Then you’ll want to choose a permanent meter that can be installed directly into your plumbing. If you only want to measure one specific area of usage, such as how much water you use in your greenhouse or sprinkler system, then a smaller, less integrated meter will probably do the trick.

Style And Features

As you can see from our list, there are several different styles of meters and each one comes with different features. Some are quite portable and can be used for multiple applications. For example, the Gardena Water Smart Flow is easy to install and can be used on hoses, faucets, and pumps. If you want to be able to measure water from different sources without having to buy multiple products, then this style will fit the bill.

If remote monitoring is what you need, then you’ll want to choose a meter that can be connected to your Wi-Fi. These meters may be a bit more expensive, but the extra cost could actually save you money in the long run. And, as we mentioned earlier, this style of meter can also give you peace of mind when you’re away from home which could in itself justify the extra cost.

Bottom Line

Water flow meters are simple tools that serve an important purpose. Whether you want to monitor your water usage for budgeting reasons or just to be more eco-friendly, a flow meter can help you do that with little to no effort on your part. All you have to do is install it and the meter will do all the measuring and math for you.

Choosing the best water flow meters may seem challenging at first, but once you know what to look for, the decision becomes an easy one. Simply consider the application and choose the style and features to match. Remember, look for a brand that guarantees accuracy and durability and you’re sure to not regret your purchase. We hope this article has given you all the information you need to choose your new water flow meter with confidence.
