Sight flow indicators are a low-cost, durable rotor-style flow indicator. Choose from models that provide basic visual flow indication or models with output for remote flow monitoring. Units are constructed of clear plastic, enabling 360° viewing of the spinning rotor for easy flow indication. Models constructed of polysulfone (PSF) have excellent chemical compatibility, high pressure and temperature ratings, and all wetted materials are FDA compliant/NSF rated for potable water applications. Models that are polycarbonate (PC) are constructed of UV-stabilized material making them ideal for outdoor applications (these models are not FDA compliant/do not have NSF rating).

Easily replace or switch outputs — install onto an existing indicator body in the field without any tools. Any sensor can be used with any flow indicator.
