WARNING: HAZARDOUS AREA USE. The Scanner 3100 is certied 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 specic installation requirements (cable glands, con-
duit seals, signal cable, RTD, etc.).
IMPORTANT When measuring steam, process connections must be designed to eliminate air pockets. This is
achieved by making sure all tubing in the cold legs slopes upward. A bottom-port MVT and block
manifold (shown in Figure 2.12) is recommended to help prevent air bubbles from being
trapped in the sensor.
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 or to a at, vertical surface using bolts and the mounting holes in the enclo-
sure. A horizontal pipe is recommended, as additional hardware may be required for a vertical pipe mount to provide
clearance for the manifold block.
