Piping the SmartLine Wireless Transmitter

Piping Arrangements
Piping arrangements vary depending upon process measurement requirements and the transmitter model.
For example, a differential pressure transmitter comes with double-ended process heads with ¼-inch
NPT connections, which can be modified to accept ½-inch NPT through optional flange adapters. Gauge
pressure transmitters are available with various connections for direct mounting to a process pipe.
A ½-inch, schedule 80, steel pipe is commonly used for transmitter integration into a process
system. Many piping arrangements use a three-valve manifold to connect the process piping to
the transmitter. A manifold makes it easy to install and remove or re-zero a transmitter without
interrupting the process. A manifold also accommodates the installation of blow-down valves to
clear debris from pressure lines.
Figure 3-12 represents a typical piping arrangement using a three-valve manifold and blow-down
lines for a differential pressure transmitter being used to measure flow.
