Extensions - Global Water FP101 User Manual

The FP101 probe handle is expandable from 3' to 6' by loosening the locking nut on the handle, pulling out
the top piece and retightening the nut. The FP201 is a three section rod expandable from 5' to 15'.
If you want to remotely read the computer, purchase a standard stereo phone jack extension cable from Radio
Shack or your local electronics supplier. Pull the computer and computer holder up off the handle. Insert
one end of the extension cable into the handle and the other into the computer holder. Now one person can
hold the probe in a manhole or in a river while another person operates the computer and records the data at
street level, or from a bridge or stream bank.
If you need to make sewer flow measurements from the street level or measure off bridges or high banks
using your FP101, you can make an extension handle by using standard schedule 40 PVC pipe:
• Use a 6" piece of 1 1/4" pipe.
• Using PVC cement, cement a 1 1/4" - 1" pipe reducer to the 6" piece.
• Cement a 1" pipe of the length required to the reducer.
• Remove the computer and holder from the flow probe.
• Insert the waterproof stereo extension cable into the top of the original handle.
• Run the extension cable through the pipe.
• Slip the 1 1/4" end over the probe handle end.
• Push on firmly and duct tape the pipe onto the handle.
This type of extension should not be used for the FP201. An extension handle kit can also be purchased
from Global Water.
