STEP 3: MOUNTING

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 Figure3).

Installations with reduced straight runs from 0 to 5 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° of horizontal.
