Spacing

XDCR SPAC -- Transducer Spacing Calculation (Value)

1. ENGLSH (Inches)

2. METRIC (Millimeters)

This value represents the one-dimensional linear measurement

between the transducers (the upstream/downstream measurement

that runs parallel to the pipe). This value is in inches if Englsh was

selected as Units; in millimeters if Metric was selected. This

measurement is taken between the alignment marks which are

scribed into the sides of the transducer blocks. See Figure 3.3.

If the transducers are being mounted using a transducer track

assembly, a measuring scale is etched into the track. Using the

alignment marks, place one transducer at 0 and the other at the

appropriate measurement.
