2000 microEFM
If the Scanner 2000 is mounted to a cone meter, consider the following best practices in addition to the best
practices listed above.
• Position the cone meter so that there are zero to ve pipe diameters upstream of the meter and zero to
three pipe diameters downstream of the meter.
• Install the meter so that the static pressure tap is upstream of the differential pressure tap. The high side of
the integral Scanner 2000 sensor must also be situated upstream.
• Install shut-off valves directly on the DP meter pressure taps. Choose a shut-off valve that is rated for the
ambient temperatures of the location and the operating pressure of the pipe in which it will be installed,
and for use with dangerous or corrosive uids or gases, if applicable. The valves must not affect the trans-
mission of the differential pressure signal.
Installation Procedure—Direct Mount to Orice Meter or Cone Meter
A Scanner 2000 can be mounted directly to an orice meter or cone meter for gas measurement. The setup
of the meter run and plumbing congurations can vary widely, depending upon the challenges existing on
location. Figure 2.5 shows a typical direct-mount installation.
WARNING HAZARDOUS AREA USE. The Scanner 2000 is certied for hazardous area use only when
installed in accordance with applicable standards and local wiring practices. Carefully
review Hazardous Area Installations, page 27, to determine specic installation require-
ments (cable glands, conduit seals, signal cable, RTD, etc.).
