illustrates the installation overview for Solitax sc Models t-line, ts-line,
and hs-line for immersion in open tanks.
The maximum distance from the mounting surface to the sensor without the use of an
extension tube is 1.5 m (4.9 ft). When that distance exceeds 1.5 m (4.9 ft), one of the
following extension tubes is required and can be ordered separately:
1.0 m (3.28 ft) extension pipe LZY413
1.8 m (5.90 ft) extension pipe LZY414
To ensure a suitable measuring position, install the probe to the following conditions:
The probe optical window must have a ground clearance of at least 30 cm (11.8 in.).
Install the probe with the optical window facing (downstream) in the direction of the
flow to minimize the risk of fouling.
Avoid installation sites where air bubbles are inconsistent. If this not possible, try
moving the probe slightly or adjusting its alignment to minimize the bubble effect.
Protect the probe against the oncoming flow of large objects, such as branches or ice
and against flow surges.
Avoid installing the probe with the optical window facing into direct light or facing a
highly-reflective surface.
