the monitor location in the manhole according to the
instructions in Securing the Cables in the Pipe and Manhole on

Note: If the pipe is large and the Doppler velocity sensor
and pressure depth sensor cables cannot reach the pipe
crown, attach the sensor cables to ½-inch (13-mm) PVC
tubing and anchor the tubing to the wall. This will help
prevent sensor damage during heavy flow.
