Cameron Scanner 3100 EFM - Thermowell Location (for Gas and Liquid Flow Runs Only); Mounting Options

Thermowell Location (for Gas and Liquid Flow Runs Only)
The process temperature input is typically supplied by an RTD installed in a thermowell downstream of the primary dif-
ferential pressure source using a 2-wire, 3-wire, or 4-wire RTD assembly. To ensure accurate measurement, the location
of the thermowell should conform to the appropriate standard.
Mounting Options
The Scanner 3100 can be mounted using the following methods:
• Direct-mount to an orifice or cone type differential pressure meter. The MVT shown in Figure 2.1 (with antenna
in Figure 2.3, page 31) may be connected to the pressure taps with stabilizers or a heavy wall nipple with adapter
anges, and a 5-valve manifold. A bottom-port MVT is recommended for gas measurement; a side-mount MVT is
recommended for liquid measurement.
• Pole-mount. The instrument can be mounted on a 2-in. pole using the mounting bosses on the side of the enclosure
and a Cameron pole mount kit (as shown in Figure 2.2, page 30). Tubing is used to connect the MVT to the orice
meter or cone meter.
