When the transmitter is mounted on its side, position the traditional
process flanges to ensure proper venting or draining. Keep drain/vent
connections oriented on the bottom for gas service and on the top for
Mount the Rosemount 3150 Series transmitter to a rigid support (i.e.
one with a fundamental mechanical resonant frequency of 40 Hz or
greater). Two mounting options are qualified for the transmitter: panel
mount or 2-inch pipe mount. A stainless steel panel bracket is
provided with the 3154. For the 3152 and 3153 series, the user has
the option of specifying either the stamped carbon steel panel bracket
or the stainless steel panel bracket.
Refer to Figure 2-5 for qualified mounting configurations for both the
panel and pipe mount options.
Orientation with respect to gravity is not critical to qualification. For
maximum accuracy, zero the transmitter after installation to cancel any
zero shift that may occur due to liquid head effect caused by mounting
The transmitter is calibrated in an upright position at the factory.
Mounting the transmitter in another position may cause the zero point to
shift by an amount equivalent to the internal liquid head within the
sensor module induced by the varied mounting position. For maximum
accuracy, zero the transmitter to cancel this effect per Section 3:
