practices listed above.
• Position the cone meter so that there are zero to five 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 fluids or gases, if applicable. The valves must not affect the transmission
of the differential pressure signal.
Installation Procedure—Direct Mount to Orifice Meter or Cone Meter
A Scanner 2000 can be mounted directly to an orifice meter or cone meter for liquid measurement using a
side-port MVT, a block manifold and two football flange adapters (Figure 2.10). The setup of the meter run
and plumbing configurations can vary widely, depending upon the challenges existing on location.

CAUTION When measuring liquid with a direct-mount Scanner 2000, process connections must be
parallel to the horizontal centerline of the meter, or below the centerline to eliminate air
pockets.
1. Verify that the meter is properly installed in the flow line (per manufacturer’s instructions).
2. Screw a football flange adapter onto each meter pressure tap using pipe tape or pipe dope to seal the
threads.
