Steam or Liquid Service (below 600 °F (315 °C))
Mount the transmitter below the process piping, adjust 10 to 15 degree above direct vertical
down. Route the impulse piping down to the transmitter and fill the system with water
through the two cross fittings.
NOTE
Ensure the drain legs are long enough to capture the dirt particles and sediment.
Top Mounting for Steam Service
(required for steam temperatures above 600 °F (315 °C))
This orientation can be used for steam at any temperature. However, it is required for
installations above 600 °F (315 °C). For remote mount installations the impulse piping
should slope up slightly from the instrument connections on the Annubar to the cross fittings
allowing condensate to drain back into the pipe. From the cross fittings, the impulse piping
should be routed downward to the transmitter and the drain legs. The transmitter should be
located below the instrument connections of the Annubar. Depending on the environmental
conditions, it may be necessary to insulate the mounting hardware.
