10.9.4 PR‑23‑W mounting specifications
PR‑23‑W Saundersâ valve body flow cell can be mounted either vertically or horizontally.
Special sensor support is not needed as the valve body (piping) supports the sensor. Either
way sensor cover must always be horizontal to avoid sedimentation or gas/air pocket on the
prism. Also installation after pump, before valve and low installation point reduces risk of
air/gas pocket. Recommended flow velocity is 1.5 ... 6 m/s (5 ... 20 ft/s).
