Mounting Options
The Scanner 2000 microEFM can be mounted using the following methods:
• Direct-mount to an orifice or cone type DP meter. The integral multi-variable sensor may be connected
to the pressure taps with stabilizers or a heavy wall nipple with adapter flanges, and a 5-valve manifold
( Figure 2.1, page 31 ). A bottom-port MVT is recommended for gas measurement; a side-mount MVT is
recommended for liquid or steam measurement.
• Direct-mount to a turbine meter. The CSA-certified instrument can be mounted to a turbine meter using a
pipe adapter and union connection ( Figure 2.2, page 31 ). The ATEX-certified instrument can be mounted to
a Barton 7000 Series meter using a turbine meter pickup extension ( Figure 2.3, page 32 ).
• Pole-mount. The instrument can be mounted on a 2-in. pole using a NuFlo hardware kit, or bulkhead-
mounted to a flat, vertical surface ( Figure 2.4, page 32 ). Pole mounting may be preferred where limited
space or pipe vibration prohibits direct-mount installation. A horizontal pipe mount is recommended for
liquid and steam installations using a side-port MVT and block manifold. Tubing is used to connect the
integral MVT to the orifice meter or cone meter. If a Scanner 2000 will be used for steam measurement, a
condensate pot must also be installed to protect the Scanner 2000 from extreme temperatures. See Mea-
suring Steam via a Differential Pressure Meter, page 42 , for details.
The following accessories are also recommended:
•
a 5-valve manifold for connecting process lines to the integral MVT
• an RTD assembly for process temperature input on gas flow runs and compensated liquid flow runs (not
recommended for steam flow runs). See Hazardous Area Installations, page 27 , for a description of RTD
options to meet specific hazardous area requirements.
• tubing and/or pipe for plumbing process connections
• explosion-proof signal cable for remote turbine connections (stranded, shielded cable is recommended)
•
terminal housing for expanding the number of inputs/outputs that can be connected to the Scanner 2000
Pole-Mount Installation
To mount the Scanner 2000 using the optional pole-mount kit, perform the following steps:
1. Determine the pipe orientation (horizontal or vertical) that will best accommodate process connections
and field wiring connections. A horizontal pipe mount is recommended for liquid and steam installations
using a side-port MVT and block manifold.
2. Connect the mounting bracket to the Scanner 2000 using the two bolts provided ( Figure 2.4, page 32 ).
3. Position the U-bolt around the pipe and through the support bracket provided with the U-bolt.
4. Align the mounting bracket against the pole so that the U-bolt passes through the mounting holes in the
bracket. Place the mounting plate over the threaded ends of the U-bolt and against the bracket, and secure
the U-bolt with the two nuts provided.
5. Install and connect process piping between the Scanner 2000 and the turbine meter with appropriate fit -
tings. Process piping installation procedures vary with each application.
