Page 7: Recommended Installation For Specific Gravity Applications
Recommended installation for specific gravity applications To ensure optimum performance of the meter, Micro Motion recommends that you install the meter inside an enclosure that is mounted to a wall. The following diagram illustrates the recommended installation of the SGM. -
Page 8: Power Requirements
For ATEX installations, you are required to install a coalescing filter and element (as supplied). Power requirements Following are the DC power requirements to operate the meter: • 24 VDC, 0.45 W maximum • Minimum 22.8 VDC with 1000 m (3280 ft) of 0.20 mm (18 AWG) power-supply cable Micro Motion Specific Gravity Meters... - Page 9 Planning • At startup, power source must provide a minimum of 0.5 A of short-term current at a minimum of 19.6 V at the power-input terminals.

Page 11: Chapter 2 Mounting
Rotate the display on the transmitter (optional) Mount the meter enclosure to a wall Micro Motion recommends that you install the meter in an enclosure that is mounted to a wall. When you order the meter with an enclosure, the meter and pipework inside the enclosure are configured at the factory to allow for easy installation of the meter in your process pipeline. - Page 12 When lifting or transporting the meter inside the enclosure, be sure not to drop the meter. While the meter enclosure is designed to minimize damage due to shocks, dropping the meter will damage the meter. 2.1.1 Mounting dimensions for a large enclosure Figure 2-2: Mounting dimensions for large enclosure Micro Motion Specific Gravity Meters...

Page 13: Connect The Gas Bypass Lines
Mounting Connect the gas bypass lines Once you have mounted the meter, you are ready to connect the gas bypass lines. There are three lines: sample gas input, sample gas output, and pressure relief. Each connector is a 1/4-inch Swagelok bulkhead fitting. These connectors are located on the outside of the enclosure. -
Page 14: Rotate The Display On The Transmitter (Optional)
If the display pins come out of the board stack with the display module, remove the pins and reinstall them. Rotate the display module to the desired position. Insert the sub-bezel pin terminals into the display module pin holes to secure the display in its new position. Micro Motion Specific Gravity Meters... - Page 15 Mounting If you have removed the display screws, line them up with the matching holes on the sub-bezel, then reinsert and tighten them. Place the display cover onto the main enclosure. Turn the display cover clockwise until it is snug. If appropriate, power up the meter.
