8. INSTALLATION
General considerations
• Probes are easily installed using the
3/4
” NPT external thread.
• Hand tighten the probe in position. Then, depending on the process, tighten one or two turns with a
wrench to secure in place. Do not exceed 10 N
•
m (7.3 lb-ft) torque specification for the probe sensor.
• Protect the probe and membrane from strong flow to prevent unstable readings. In turbulent aeration
basin installations, place the probe in a weir for more accurate readings.
• Do not install the probe in an upside-down position.
• Provisions must be made for the removal of the probe from the process.
• Consider probe accessibility for maintenance when selecting placement.
