Product Description
SFI Series sight flow indicators is perfect for simple flow applications that don’t require calibrated flow indicators. Both, the Rising Ball or Paddle Style, are constructed of durable materials and can used for a variety of flow media. With the Ball Style, the ball will lift out of the socket with increase flow until it becomes visible. If there is no flow, the white PTFE ball will remain situated in the body socket. This style requires that the product be mounted horizontally with the glass dome facing up.
The Paddle Style indicator will allow the paddle to rotate which indicates that flow exists. This style can be mounted either horizontally or vertically and it allows for bi-directional flow indicating with minimal pressure losses.
