STEP 2: Detach The Cable Quick Connects
The sensor cable is tted with an IP68 rated Quick Connect tting at the sensor connection. For ease of installation,
remove the cable from the sensor and set aside. Compression gland seals are available as an option instead of the
Quick Connect cable ttings.
IMPORTANT: When the Quick-Connect cable connection is not attached to the sensor, ensure that
the threaded caps are attached to the sensor connection and the cable connection to keep the wire
connectors free of dirt and corrosion. When the cable is connected to the sensor, connect the end caps
together to keep their interior free from dirt and corrosion.

STEP 3: Verify Sensor Installation Location - Upstream And Downstream Straight-Pipe Run Recommendations
Figure 6. Sensor Cable Fittings
Flow disturbers such as partially open valves cause ow disturbances that can adversely aect ow meter accuracy.
The table below provides suggestions for the placement of the FPI Mag sensor upstream and downstream
of common ow disturbers to meet specication accuracy. The upstream and downstream straight-pipe
recommendations are conservative, based on research completed in the McCrometer NIST traceable calibration
facility. In many cases, the installation distances suggested below can be shortened depending on ow conditions
and piping layout.
