2" Flow Indicator – Paddlewheel Type, CF8M Stainless Steel, Class 150 RF Flanged

This 2" (DN50) flow indicator is a durable, two-way inline monitoring device that provides real-time visual confirmation of fluid movement using a rotating paddlewheel mechanism. The rotating paddlewheel, housed behind a clear, impact-resistant window, allows easy verification of flow direction and rate at a glance—ideal for confirming proper system operation.

Engineered with a corrosion-resistant CF8M stainless steel body (ASTM A351 equivalent to 316 SS), the unit is suited for use in aggressive chemical, water treatment, and general industrial applications. The raised face (RF) flanged ends conform to ANSI B16.5 Class 150 standards for seamless integration into standard piping systems. Pressure and temperature tolerances support up to 19 bar (275 psi) and 200°C, making it suitable for a wide range of operating environments.

Tested per API 598 standards, the unit ensures robust sealing integrity and reliable performance under fluctuating conditions. Its compact face-to-face dimension (~203 mm) and standard bolt pattern make it easy to install and maintain.
