Hot Tap Flow Sensors - Series 225 & 226

The 225BR and 226BR/226SS flow sensors are used for flow measuring applications in most metallic or non-metallic pipes where it would be difficult to shut down or drain the line for installation or service. The 225 flow sensor features a gate valve for isolation. The 226 flow sensor uses a ball valve. If the pipe is to be hot tapped, the ball valve is recommended.

Provides higher, more consistent torque than four-bladed impeller designs.

Used for flow measuring applications in most metallic or non-metallic pipes where it would be difficult to shut down or drain the line for installation or service.

  • Forward swept impeller shape. Provides higher, more consistent torque and is less prone to be fouled by water borne debris.
  • Forward curved shape coupled with the absence of magnetic drag. Provides improved operation and repeatability at lower flow rates.
