Depth Sensor Node Bridge Mounted Replacement Procedure

Using an adjustable or socket wrench, remove the four 3/4" nuts and washers from the U-brackets attaching the long strut channel to the bridge.

Note: You do not have to remove the two 3/4" hex head screws and washers attaching the U-brackets to the long strut channel.

These are the two small strut channels attaching the node to the long strut channel.

Using a 1/2" adjustable or socket wrench, remove the four 1/2" hex head screws attaching the old node to the small strut channels.

Be sure to remove the nuts and washers on the inside of the small strut channels as well. (Total: Four 1/2" hex head screws, four 1/2" nuts, and four washers)

Obtain a new depth sensor node and attach a padlock to the new depth sensor node.

This step will use the same 1/2" hex head screws, 1/2" nuts, and washers from the removal of the old depth sensor node.

Using a 1/2" adjustable or socket wrench, attach the new depth sensor node to the small strut channels with four 1/2" hex head screws, 1/2" nuts, and washers. Tighten and secure.

This is what the bridge mount looks like before reattaching the long strut channel with the new depth sensor node.

Line up and place the U-brackets, still attached to the long strut channel, onto the bridge mount.

Using a 3/4" adjustable or socket wrench, secure the long strut channel and U-brackets to the bridge with the 3/4" nuts and washers. Tighten and secure.

Using a (weighted) tape measure, measure and record the distance from the bottom of the depth sensor node to the bottom of the river.

The bottom of the depth sensor node is defined as the bottom of the sensor cone.
