• There are no pipe run requirements for Micro Motion sensors. Straight runs of pipe upstream or downstream are unnecessary. • If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward through the sensor. Gases may flow upward or downward. • Keep the sensor tubes full of process fluid. • For halting flow thr[...]

5 Supplementary information Topics covered in this chapter: • Purge the sensor case • About rupture disks 5.1 Purge the sensor case If the sensor has purge fittings, they should remain sealed at all times. After a purge plug has been removed, the sensor case should be purged with argon or nitrogen and resealed. Purging the case protects interna[...]

4. Connect the supply of nitrogen or argon gas to the inlet purge connection or open inlet purge line. Leave the outlet connection open. • Exercise caution to avoid introducing dirt, moisture, rust, or other contaminants into the sensor case. • If the purge gas is heavier than air (such as argon), locate the inlet lower than the outlet, so that[...]
