Blue-White FLOWREAD R-320 Flow Meter | 20-120 GPM, 2" ID Pipe, Accurate Pool Flow

Overview

Meet the Blue-White FLOWREAD R-320, a compact acrylic flow meter designed for 2-inch ID pool piping. It provides a clear, repeatable readout of your pool’s flow rate, helping you tune pump output with confidence and balance filtration, chemistry, and energy use without guesswork.

Why the right flow rate matters

Accurate flow readings support proper filtration, reduce the need for excessive chemicals, and help protect equipment by keeping flow within safe ranges. When paired with a variable-speed pump, a precise reading makes it easier to run the system efficiently and maintain comfortable pool conditions.

Note that while flow data can influence decisions, it does not replace routine maintenance or professional advice. The goal is informed adjustments and better system awareness.

Key benefits at a glance

• Flow rate accuracy of ±5% enables precise pump adjustments and potential energy savings.
• Easy-to-read UV‑screened scale is visible in sunlight and shade, readable from multiple angles.
• Installs on 2" ID PVC pipe with no unions, adapters, primer, or cement required.
• Does not impede flow, preserving system performance while delivering vital readings.

What’s included

• One machined acrylic flow meter
• One rubber gasket seal
• Two stainless steel clamps

Installation and durability

Designed for outdoor use, the FLOWREAD R-320 withstands sun exposure and temperature variations. It is proudly manufactured in the United States, offering solid build quality and reliable support for pool owners nationwide.

DOE context and practical use

With energy standards encouraging variable-speed pumps, an accurate flow reading helps you set the pump to the right level for longer periods. This practice can support energy-efficient operation and smoother system performance overall.

In practice, pool owners use the FLOWREAD R-320 to gain visibility into how their pump speed translates to flow in the plumbing, enabling smarter adjustments and a better sense of how changes affect filtration, heating, and circulation.

Technical notes

The meter is spec’d for 2" ID piping and comes with a robust gasket and clamps for straightforward installation, without the need for unions or special tools. The unit’s acrylic construction is clear for easy reading and long-lasting visibility.
