22.2.4. Installation Tee
• Install the probe in a tee, horizontally, and direct the flow into the opening at the bottom of the probe.
• Upward flow direction must always be ensured.
• Maintain a stable flow rate to minimize interferences from bubbles and settling of particulates.
• Wrap PTFE tape around the probe’s threads and fittings before mounting.
