2.5.2 Installation on Non Metal Vessels
The Impulse® TDR requires a metal surface at the mounting. When
mounting either a Single Rod or Single Cable probe without Wave Guide
Nozzle Eliminator on a non-metal vessel, use a 2” or greater ANSI metal
flange to act as a “launch plate” directly at the instrument mounting. A
launch plate can be fabricated with an 8” (200 mm) diameter metal disc
that can be threaded in constant contact with the metal NPT mounting
thread placed above a non-metal flange or thread mounting.
Twin element probes (coaxial, twin rod or twin cable) do not require a
launch plate.
