1.2 Description
The Daniel Senior Orifice Fitting is an orifice plate holding device that houses, and accurately
positions, an orifice plate within a pipe or tube to measure fluid flow. It is just one component of
an orifice plate flow measurement system. The Daniel Senior Orifice Fitting (Senior) is designed
to:
• Position an orifice plate, concentric to flow moving through a line, within API MPMS
Chapter 14.3, Part 2 (AGA-3) or ISO 5167 installation requirements.
• Allow personnel to remove and replace an orifice plate without disturbing flow
measurement system piping and with little, or no, interruption in service.
The orifice plate within a Senior restricts the fluid moving through a pipe. This restriction creates
a change in static pipe pressure of the fluid. Instruments measure this change in pressure prior
to the fluid passing through the orifice plate, and once again after it passes the plate. Instrumen-
tation then combines that information, along with other data gathered from the flowing fluid,
and calculates the amount of fluid that passes through the system.
The Daniel Senior Orifice Fitting dual chamber design allows for the inspection and replacement
of an orifice plate with little or no interruption in service and without removing the Senior from
the system.
The first chamber, or Body (4), properly positions the orifice plate in the flow stream. The
second chamber, or Top (14), is a temporary holding place for the orifice plate during removing
or installing operations (refer to
Section 4: Orifice plate installation and removal instructions ).
