□ For optimal performance, install the sensor in the preferred orientation. The sensorwill work in any orientation as long as the flow tubes remain full of process fluid. Preferred sensor orientation Table 1-3: Process Preferred orientation Alternate orientations Liquids Gases Slurries □ Install the...

• There are no pipe run requirements for Micro Motion sensors. Straight runs of pipeupstream or downstream are unnecessary. • If the sensor is installed in a vertical pipeline, liquids and slurries should flow upwardthrough the sensor. Gases may flow upward or downward. • Keep the sensor tubes full ...
