Direct-Mount Meter and Transmitter Installation (Model 3xxCi)
The LEFM 3xxCi flowmeters are designed for use with a broad range of process and environmental
conditions. Durable construction permits conventional installation practices. The flowmeter body is typically
fabricated of stainless steel, carbon steel, or duplex steel, depending on customer requirements. The
flowmeter is designed to be as strong as or stronger than pipe and flanges of the same schedule, pressure
class, and material. For site stress analysis, the meter can be conservatively treated as equivalent pipe.
Installation procedures vary, depending on whether the transmitter is attached directly to the meter body, or
mounted remotely from the meter body. This section describes the direct-mount installation in which the
transmitter is mounted directly to the meter body (Model 380Ci). Section 1
addresses the remote-mount
installation method in which the transmitter is mounted separately from the flowmeter, typically due to
extreme environmental reasons (for example, high or low pipe temperatures). Remote mounting of the
electronics is for Model 380Ci-R.
Flowmeter Body Installation – Best Practices
The weights of the flowmeter body are listed in
Table 1.3
and Table 1.4. Never use the transmitter,
conduit or junction boxes for lifting or maneuvering the meter body. These components are not
designed for the forces required to move the meter body and could be damaged.
If the equipment is likely to come into contact with aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from being adversely affected,
thus ensuring that the type of protection is not compromised.
No external supports or special mounting pads are required or recommended for the
LEFM meter body. However, the piping immediately upstream and downstream of the flowmeter should be
well supported in accordance with good piping practices and site seismic requirements. See Section 1 for
LEFM weight and size information.
