3.2 Sensor Installation
Figure 4 on page 10 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.
