Measure the pipe diameter
The correct diameter of the pipe or channel is necessary for accurate
flow calculations.
1. Measure the inside pipe diameter (ID) at three locations. Refer to
Figure 19. Make sure that the measurements are accurate.
2. Calculate the average of the three measurements. Record this
number for use during the software setup for the site.

Wiring safety information
D A N G E R
Electrocution hazard. Always remove power to the instrument before
making electrical connections.
Electrostatic discharge (ESD) considerations
N O T I C E
Potential Instrument Damage. Delicate internal electronic components
can be damaged by static electricity, resulting in degraded
performance or eventual failure.
Refer to the steps in this procedure to prevent ESD damage to the
instrument:
• Touch an earth-grounded metal surface such as the chassis of an
instrument, a metal conduit or pipe to discharge static electricity from
the body.
• Avoid excessive movement. Transport static-sensitive components in
anti-static containers or packages.
• Wear a wrist strap connected by a wire to earth ground.
• Work in a static-safe area with anti-static floor pads and work bench
pads.
Connect the logger or controller
Connect the cable from the Flo-Dar sensor to the logger or the controller:
• Logger–connect the cable from the Flo-Dar sensor to the sensor
connector on the logger. If the Flo-Dar sensor has the SVS
component, connect the cable from the SVS component to the sensor
connector on the logger.
• Controller–connect the cable from the Flo-Dar sensor to the correct
terminal in the controller. If the Flo-Dar sensor has the SVS
component, connect the cable from the SVS component to the correct
terminal in the controller. Refer to the controller documentation for the
correct terminal locations.
