Notes:
• Water or process fluids must not enter the
connecting threads: this could cause reflections
at the connection, which will appear as false
100 mm (4")
echoes.
• Apply a small amount of PTFE paste to the
antenna threads before threading the antenna
together, and tighten slowly. Ensure that the rod
50 mm (2")
sections mate securely with no gaps. Do not
apply too much PTFE paste or the parts will not
mate securely.
• Do not use wrenches or pliers. Hand tighten only
(except in pressure applications: see warning
above).
