Process scope

Yoshitake sight glasses and flow sights provide local visual confirmation of liquid presence, direction, or movement. The local range includes plain-view, flapper, ball/spinner, and nozzle styles with screwed or flanged connections. Select the viewing principle for the process evidence required, then confirm fluid, pressure, temperature, glass, body material, and installation orientation.

Project-specific checks

1. Define the observation required: liquid presence, direction, turbulence, or positive movement indication.
2. Confirm fluid clarity, solids, viscosity, pressure, temperature, and glass/wetted-material compatibility.
3. Match screwed or flanged interface, line size, orientation, and safe viewing access.
4. Plan cleaning, drainage, illumination, and replacement access without exposing personnel to process fluid.

Final verification

This guide groups local Yoshitake catalogue pages for preliminary engineering review. The model-specific Yoshitake documentation, sizing calculation, materials confirmation, and applicable site requirements control the final order and installation decision.
