Cameron Scanner 3100 EFM - Direct Mount to Orifice Meter or Cone Meter

Direct Mount to Orice Meter or Cone Meter
A Scanner 3100 can be mounted directly to an orice meter or cone meter for liquid measurement using a side-port
MVT, a block manifold and two football ange adapters (Figure 2.13, page 48). The setup of the meter run and plumb-
ing congurations can vary widely, depending upon the challenges existing on location.
CAUTION When measuring liquid with a direct-mount Scanner 3100, process connections must be parallel to
the horizontal center line of the meter, or below the center line to eliminate air pockets.
1. Verify that the meter is properly installed in the ow line (per manufacturer’s instructions).
2. Screw a football ange adapter onto each meter pressure tap using pipe tape or pipe dope to seal the threads.
3. Align the bolt holes in the Scanner 3100 MVT and manifold, and install bolts to mate these components to the foot-
ball anges, using O-rings as appropriate. Torque the bolts to the manufacturer’s specication.
4. Route any additional inputs/outputs, communications connections, etc. through a conduit opening in the top of the
Scanner 3100. For hazardous areas, review Hazardous Area Precautions, page 27.
5. Verify that all manifold valves are closed and ll the meter with process uid.
6. Loosen one of the vent screws in the side of the MVT.
7. Open the equalizer valves and the vent valve on the manifold.
8. Slowly open one of the bypass/block valves on the manifold. Process uid should immediately spurt from the MVT
vent.
9. When air bubbles are no longer visible around the MVT vent, tighten the MVT vent screw.
10. Loosen the other vent screw in the side of the MVT, and repeat steps 7 through 9.
11. Perform a manifold leak test as described in Performing a Manifold Leak Test, page 51.
12. Verify the zero offset (if required) and other calibration points (if desired). See the Scanner 3100 Web Interface User
Manual for complete instructions. See also Zero Offset (Static Pressure or Differential Pressure), page 51, Differ-
ential Pressure Calibration and Verication, page 53, and Static Pressure Calibration and Verication, page 52.
CAUTION Do not put the Scanner into operation until the valves are positioned properly so that pressure is
supplied to both sides of the MVT. For instructions on proper valve positions, see Placing the Scan-
ner into Operation, page 54.
