Installation
Process flange orientation
Orient the process flanges on a remote mounted flowmeter so that process connections can be
made. For safety reasons, orient the drain/vent valves so that process fluid is directed away from
technicians when the valves are used. In addition, consider the possible need for a testing or
calibration input.
Housing rotation
The electronics housing may be rotated up to 180 degrees (left or right) to improve field access
to the two compartments or to better view the optional LCD meter. To rotate the housing,
release the housing rotation set screw and turn the housing up to 180 degrees.
Electronics housing
Terminal side
The circuit compartment should not routinely need to be opened when the unit is in service.
Wiring connections are made through the conduit openings on the top or side of the housing.
The field terminal side is marked on the electronics housing. Mount the flowmeter so that the
terminal side is accessible. A 0.75-in. (19 mm) clearance is required for cover removal. Use a
conduit plug on the unused side of the conduit opening. A 3-in. (76 mm) clearance is required
for cover removal if a meter is installed.
Cover installations
Always install the electronics housing covers metal-to-metal to ensure a proper seal.
