Model 227A Dierential Pressure Indicator Section 1
Figure 1.3—Indicator mechanism for inverted case
Because the indicator design affects the readout, only inverted scale plates
may be used with inverted indicators, and only universal scale plates may be
used with universal type units. See Table 4.1, page 17
descriptions and part numbers.
