Quick Installation and Startup
2.7 Mounting
2.7.1 Upstream/downstream piping
To ensure specified accuracy over widely varying process conditions, install the sensor with a
minimum of five straight pipe diameters upstream and two pipe diameters downstream from the
electrode plane (see
Figure2-3).
Figure 2-3. Upstream and Downstream Straight Run
Installations with reduced upstream and downstream straight runs are possible. In reduced straight
run installations, the meter may not meet absolute accuracy specifications. Reported flow rates will
still be highly repeatable.
2.7.2 Flow direction
The sensor should be mounted so that the arrow points in the direction of flow. See Figure 2-4.
