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 liquid mea-
surement (Figure 2.14, page 49). The setup of the meter run and plumbing congurations can vary widely, depending
upon the challenges existing on location.
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.).
CAUTION When measuring liquid, process connections must be designed to eliminate air pockets. This is
achieved by mounting the sensor below the metering device and sloping all tubing downward from
the meter to the sensor. A side-port MVT and block manifold (shown in Figure 2.14, page 49) is
recommended to help prevent air bubbles from being trapped in the sensor.
If a bottom-port MVT is used, the bottom process ports must be plugged or replaced with a drain
valve, and side vents must be used for process connections. A block manifold is not recommended
for use with bottom port MVTs. Contact a Cameron eld representative for assistance.
1. Verify that the meter is properly installed in the ow line (per manufacturer’s instructions).
2. Mount the Scanner 3100 to a 2-in. pipe using the mounting bosses on the side of the enclosure and a Cameron pole
mount kit. See Pole-Mounting the Scanner 3100, page 30 for detailed mounting instructions.
3. Install tubing and ttings to connect the high-pressure and low-pressure taps of the differential pressure meter to the
process connections of the block manifold. Install a pair of shutoff valves near the high and low ports of the differ-
ential pressure meter. Use a suitable compound or tape on all threaded process connections.
