OUNTING
Upstream/Downstream Piping
To ensure specification accuracy over widely varying process conditions, install the sensor a
minimum of five straight pipe diameters upstream and two pipe diameters downstream from
the electrode plane (see Figure 3).
Installations with reduced straight runs from 0 to five pipe diameters are possible. In reduced
straight pipe run installations, performance will shift to as much as 0.5% of rate. Reported
flow rates will still be highly repeatable.
Flow Direction
The sensor should be mounted so the FORWARD end of the flow arrow, shown on the
sensor identification tag, points in the direction of flow through the sensor.
Sensor Orientation
The sensor should be installed in a position that ensures the sensor remains full during
operation. Vertical installation allows upward process fluid flow and keeps the
cross-sectional area full, regardless of flow rate. Horizontal installation should be restricted
to low piping sections that are normally full. In these cases, orient the electrode plane to
within 45 degrees of horizontal.
