Flow meter FlowVis Dn40 (50 mm glued) with non-return valve

A revolution in reliable flow measurement

Ingenious in concept and flawless in operation, FlowVis® is revolutionising the way pool owners and professionals alike measure flow. FlowVis® is the most accurate, reliable, NSF-certified flow meter ever developed for pools, spas, fountains and water features.

The patented concept allows FlowVis® models to be installed alongside other accessories without the need for straight pipes FlowVis® can also be installed horizontally, vertically and even upside down.

Advantages FlowVis

• Easy to install and requires no calibration, making it extremely easy to use.
• Reduces the use of chemicals.
• Can be installed in any position and close to any other piping element.
• Accuracy: 98%.
• Minimal pressure drop.

Variable Speed

Installing a variable speed pump to save energy is a good idea, but the only way to know what speed to set the pump at is to know the flow rate.

FlowVis allows you to:

• Maximise potential energy savings.
• Achieve adequate surface cleanliness.
• Reduce chemical costs.
• Keep the pool clean.
• Ensure heater efficiency.
• Achieve accurate and repeatable valve positioning.

In order to achieve the requirements, it is essential to establish what flow rate is required. If the flow rate setting is too high more energy will be used than required, if the flow rate setting is too low the result will be a dirty pool. As shown in the table below, using FlowVis® to accurately set the required pump speed will result in economic payback in just one year.
