Note: The accuracy of the pipe inner diameter measurement is critical
for high accuracy flow rate measurements as there is a direct
correlation between this measurement and the reported flow rate.
7.5 Sensor Band Installation
It will be helpful to have a second person available to assist with
holding the sensor assembly in position during installation.
Note: Prior to installing the sensor band, remove and save the plastic
bag from the sensor band that contains two sensor calibration factor
labels. These will be used as described later in this manual for input
to the transmitter.
Ensure there is no dirt or other foreign material on the sensor
assembly. Remove dirt or foreign matter using a clean cloth
dampened with water.
If the sensor band was shipped with a sensor band shorting plug
installed on the sensor band to preamplifier cable connector, ensure
the sensor band-shorting plug is installed on the sensor band cable
prior to installing sensor band. Sensors bands with an ‘R” in the Part
Number suffix (e.g. Part #: 20686-26-R) do not require a shorting plug.
Wrap the compliant sheet around the process pipe. The ends of the
compliant sheet should be positioned at the weld seam on the pipe (if
there is one). Refer to the following figures.
