    ™ Fieldbus Section 2 Scanner 2000 microEFM for F ® oundation CAUTION Before starting the system, remove the caps and add water or antifreeze if necessary to completely fill the pots and cold legs. Air trapped in the lines will produce errors in dif- ferential pressure measurements. WARNING: EXPLOSION RISK. Housing temperature must not exceed 70°C (158°F). Excessive temperatures, which could result from ambient conditions combined with radiated and conduc- tive heat from the process, could cause the internal lithium battery to ignite or explode. Installation Procedure—Remote Mount to Orifice Meter or Cone Meter A Scanner 2000 can be mounted remotely and connected to an orifice meter or cone meter with tubing for steam measurement.
  • Page 31 ™ Fieldbus Scanner 2000 microEFM for F Section 2 ® oundation CAUTION When measuring steam, process connections must be designed to eliminate air pock- ets. This is achieved by making sure all tubing in the cold legs slopes upward. A side- port MVT and block manifold (shown in Figure 2.9) 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 field representative for assistance. 1. Verify that the meter is properly installed in the flow line (per manufacturer’s instructions). 2. Mount the Scanner 2000 to a 2-in. pipe or to a flat, vertical surface using bolts and the mounting holes in the enclosure.

Install tubing and fittings to connect the high-pressure and low-pressure taps of the DP meter to the pro- cess connections of the block manifold. Install a pair of shut-off valves near the high and low ports of the DP meter.
  • Page 37 ™ Fieldbus Scanner 2000 microEFM for F Section 2 ® oundation Important If the process fluid does not present an environmental risk and is stable when depressur- ized, it may be used to bleed air from the lines. If the process fluid can contaminate the environment, or is highly volatile when depressurized as with liquified gases, a different seal fluid should be used to fill the legs. An ideal seal fluid is one that does not dissolve in the process fluid. Bleeding with Process Fluid a. Make sure the shut-off valves in the tubing near the meter pressure taps are closed, and the meter is filled with process fluid. b.
