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

WARNING—HAZARDOUS AREA USE. The Scanner 3100 is certied for hazardous area use only when
installed in accordance with applicable standards and local wiring practices. Carefully review Hazardous
Area Precautions, page 27 to determine specic installation requirements (cable glands, conduit seals,
signal cable, RTD, etc.).
1. Verify that the meter is properly installed in the ow line (per manufacturer’s instructions).
2. Bolt a ange-by-ange 5-valve manifold (as recommended by Cameron) to the Scanner 3100 MVT sensor.
a. Locate the H and L markings on the MVT sensor body and position the MVT/manifold assembly so that the
upstream side of the ow line can easily be connected to the sensor’s “High” port and the downstream side of
the ow line can be connected to the sensor’s “Low” port. The Scanner 3100 enclosure can be rotated to face
the desired direction.
b. Position the manifold so that all valves are accessible from the front of the instrument.
3. Connect the Scanner 3100 and manifold assembly to the differential pressure meter. Hardware requirements will
vary, depending upon the installation conguration. Minimally, an adapter that can span between the threaded pres-
sure tap/orice ange connector and the non-threaded manifold is required. This adapter can be a one-piece stabi-
lizer (often preferred for added strength and stability) or a short heavy-wall pipe nipple attached to a football ange
(available from Cameron). Use a suitable compound or tape on all threaded process connections.
CAUTION Do not use Teon tape on the threads of the union, adapter, or pipe plugs that may be installed in
the enclosure. Use of Teon tape will void the explosion-proof rating of the instrument.
4. Install the RTD assembly in the thermowell. Route the RTD assembly cable through a conduit opening in the top
of the Scanner 3100 to connect to the terminal board. A wiring diagram for the RTD assembly is provided in Figure
3.6, page 59. For hazardous areas, review Hazardous Area Precautions, page 27.
5. Route any additional inputs/outputs or COM connections, etc. through a conduit opening in the top of the Scanner
3100. For hazardous areas, review Hazardous Area Precautions, page 27.
6. Perform a manifold leak test as described in Performing a Manifold Leak Test, page 51.
7. 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.
Remote Mount to Orice Meter or Cone Meter
A Scanner 3100 can be mounted remotely and connected to an orice meter or cone meter with tubing for gas measure-
ment. The setup of the meter run and plumbing congurations can vary widely, depending upon the challenges existing
on location. Figure 2.10, page 40 shows a typical remote-mount gas run installation.
WARNING—HAZARDOUS AREA USE. The Scanner 3100 is certied for hazardous area use only when
installed in accordance with applicable standards and local wiring practices. Carefully review Hazardous
Area Precautions, page 27 to determine specic installation requirements (cable glands, conduit seals,
signal cable, RTD, etc.).
Note To prevent ttings from turning and to avoid putting tension on stainless steel tubing, use a backup wrench to at-
tach stainless steel tubing to a manifold, shutoff valves, or sensor ports.
