Inline Flow Meter

An inline flow meter for PVC pipe helps you verify real-world flow rates in recirculating water systems so filters and UV units can operate within their intended ranges. This inline design provides clear, repeatable readings without relying on sticking floats or paddle wheels, making it a practical choice when you want reliable monitoring with minimal maintenance.

Why use this meter

• Designed for filtration and UV setups: Helps you confirm that your system is delivering the flow rate your components require.
• Inline, easy-to-read format: Provides quick visual confirmation of flow without complex electronics.
• Flexible installation: Can be installed next to tees or elbows and in any position for simpler plumbing layouts.

How to choose and install

Select the size that matches your existing plumbing and verify that your expected operating flow falls within the 10–110 GPM range. An inline flow meter for PVC pipe is especially useful downstream of pumps and upstream of filters/UV units, where confirming actual flow can help you troubleshoot performance issues and fine-tune system settings. Always follow best practices for PVC joining and ensure the line is depressurized before installation.
