Figure 3-6: Mounting Bolts and Bolt Configurations for Coplanar Flange
Dimensions are in inches (millimeters).
Description Size in inches (mm)
Flange Bolts 1.75 (44)
Flange/Adapter Bolts 2.88 (73)
Manifold/Flange Bolts 2.25 (57)
Note
Rosemount 2051T transmitters are direct mount and do not require bolts for
process connection.
Mounting requirements
Impulse piping configurations depend on specific measurement conditions. Refer to
Figure 3-7 for examples of the following mounting configurations:
Liquid flow measurement
• Place taps to the side of the line to prevent sediment deposits on the process isolators.
• Mount the transmitter beside or below the taps so gases vent into the process line.
• Mount drain/vent valve upward to allow gases to vent.
Gas flow measurement
• Place taps in the top or side of the line.
• Mount the transmitter beside or above the taps so to drain liquid into the process line.
Steam flow measurement
• Place taps to the side of the line.
• Mount the transmitter below the taps to ensure that impulse piping will remain filled
with condensate.
• In steam service above 250 °F (121 °C), fill impulse lines with water to prevent steam
from contacting the transmitter directly and to ensure accurate measurement start-up.
