Flow Vis flow meters – the best water flow meters for sale today

The FlowVis is a revolutionary, affordable, and highly accurate flow meter. The best part is that the FlowVis™ is more than a flow meter; it is also a fully functioning check valve. Simply attach the retrofit FlowVis™ to your existing Jandy check valve and it will show you your flow rate. A specifically designed calibration spring, indicating arm, and an extended height valve body lid constitute the fundamentals of the FlowVis design concept.
The FlowVis™ is a revolution in reliable flow measurement. It is the most advanced, affordable, and reliable precision flow meter designed specifically for pools, spas, fountains, and water features.

How Flow Vis Flow Meter Can Transform Your Pool and Spa Automation Experience

A proper pump sizing and selection for your pool, hot tub, irrigation, or fountain is crucial when it comes to getting the most out of your ownership experience. To achieve it, a few calculations are required.  If you set the speed too high, your pool will consume more water and electricity than it should, resulting in unnecessarily high energy bills. On the other hand, if you set the speed too low, your pump won’t be able to keep the water clean, and you’ll eventually end up with a stagnant spa or pool that’s a breeding ground for algae and germs of all sorts.

That’s where hot tub and swimming pool flow meters such as Kona Lab’s FlowVis flow meter come in. These devices measure the water flow rate i.e. the rate at which the liquid is circulated through the filtering system and back to the spa or pool. By giving you this information, they enable you to correctly calculate your pool or spa’s pump. This optimizes your energy usage and keeps the water clean and healthy. Finally, it maximizes the longevity of your pump, allowing you to get the maximum value out of your investment.

FlowVis flow meter installation is quick and hassle-free

Just for comparison, a typical low-end flow meter has to be positioned on a straight, long section of pipe so as to correctly measure the flow rate. Ergo, it can’t be mounted near 90 degree turns in the pipe. The best position allows for two times the pipe diameter to be in front of the flow meter, and four times the pipe diameter behind it. For example, if a flowmeter is set on a four-inch pipe, it would require sixteen inches of pipe to be behind it, and eight inches in front of it. The flow meter always has to match the pipe diameter it’s placed on.

Here at Kona Labs, we don’t think you should be forced to go to such troubles just to fit a flow meter. That’s why our FlowVis flow meter is designed to easily retrofit to an existing jandy check valve. FlowVis Retrofit is a simple, fast procedure that can be completed in a few minutes. It’s one of the many reasons why FlowVis is the best of all water flow meters for sale today and why it offers unmatched pool, fountain, and spa automation system.

The benefits of Flow Vis retrofit flow meters

A flow meter consists of three parts. The primary device through which water passes, the transducer which measures the liquid going through the primary device, and the transmitter which converts the transducer’s measurement and displays it in readable numbers. Some of its benefits include:

  • Superb accuracy – Flow Vis offers unparalleled 97.9% accuracy in water flow measurement.
  • Excellent skimming – Flow Vis enables you to optimize your skimming efficiency and achieve ideal flow rates.
  • Filter efficiency – perfect flow rates are necessary to maximize the benefit you get from your water filters, rendering your pool, spa, or fountain water fresh and algae-free.
