Transmitter location The suggested mounting location for the transmitter depends on the
process to be measured. Figure 11 shows the transmitter located above the
tap for gas flow measurement. This arrangement allows for condensate to
drain away from the transmitter.
Figure 12 shows the transmitter located below the tap for liquid or steam
flow measurement. This arrangement minimizes the static head effect of
the condensate. Although the transmitter can be located level with or
above the tap, this arrangement requires a siphon to protect the transmitter
from process steam. (The siphon retains water as a “fill fluid.”)
