Paddlewheel Flow Meters In Aquatics Applications

Commercial Aquatic facilities, such as public pools and water parks, must meet specific city health standards of safety to remain open. For example, these aquatic facilities must verify that the turnover rate meets the required range to satisfy local regulations. As such, flow meters are required on all commercial aquatic features to facilitate inspection and confirm an adequate flow rate through the filtration system.

One of the simplest ways to quickly and reliably scan flow rates is with a paddlewheel flow meter. This device comprises a paddlewheel sensor, a display, and a pipe fitting. The paddlewheel sensor incorporates a rotating paddlewheel. As water enters, the magnets in the blades flow past the sensor, and the paddlewheel meter generates a frequency and voltage signal proportional to the flow rate.

When choosing a paddlewheel flow meter, consider the flow range, the unit's accuracy and repeatability, the pipe diameter in your system, and your preferred mounting style. Available mounting styles include inline, insertion, and non-invasive.
