MODEL 1195 INTEGRAL
ORIFICE
The orifice assembly installs directly into the customer’s process piping
with threaded, welded, or flanged connections. The transmitter may be
mounted directly to the orifice assembly or mounted remotely using
optional remote connectors.
Available options allow the user to have the Model 1195 sized for
specific operating conditions and laboratory flow calibrated for
improved accuracy.
Appendix C: Calculation Data Sheets shows the Calculation Data Sheet
that specifies the physical parameters of the orifice from a detailed
sizing calculation. The calculation should be retained for future
reference.

Mounting The flow measurement’s accuracy depends to a great extent on proper
installation of the transmitter and orifice assembly. Mounting the
transmitter close to the process and using a minimum of piping ensures
the greatest accuracy. Keep in mind, however, the need for easy access,
safety of personnel, practical field calibration, and a suitable
transmitter environment. In general, install the transmitter so as to
minimize vibration, shock, and temperature fluctuation.
