This invention relates to plate carriers, and
more particularly to plate carriers adapted to be
positioned within a conduit through which fluid
is passing under pressure.
In the ñrstembodiment of my invention as il
lustrated in the accompanying drawing, I have
indicated the plate carrier embodying my inven
tion as adapted in an orifice fitting of the type
utilized for determining` the flow of a fluid
through a conduit in which thecriñce fitting is

adapted to be moved to and from position across
the path of fluid flowing through the fitting I and
translated through a valve member I0 into a
chamber II where the carrier may be withdrawn
for replacement, change or repair of the plate 5
as may be desired after the valve I 0 has been
closed to prevent escape of fluid .from the line
within which the fitting I is mounted.
In removable orifice fittings one of the principal
dif?culties encountered is in maintaining the
plate 5 in fluid-tight relation within the carrier

Having fully described my invention, it is to
