  1. Depth Sensor Node Bridge Mounted Replacement Procedure, Removing the U-brackets from the bridge mount: 步骤 1 中的图像 1,3 Depth Sensor Node Bridge Mounted Replacement Procedure, Removing the U-brackets from the bridge mount: 步骤 1 中的图像 2,3 Depth Sensor Node Bridge Mounted Replacement Procedure, Removing the U-brackets from the bridge mount: 步骤 1 中的图像 3,3
    • 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.

    • Hold the node and long strut channel securely to ensure that they do not fall during this process.

    • 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.

  2. Depth Sensor Node Bridge Mounted Replacement Procedure, Removing the old depth sensor node from the small strut channels: 步骤 2 中的图像 1,3 Depth Sensor Node Bridge Mounted Replacement Procedure, Removing the old depth sensor node from the small strut channels: 步骤 2 中的图像 2,3 Depth Sensor Node Bridge Mounted Replacement Procedure, Removing the old depth sensor node from the small strut channels: 步骤 2 中的图像 3,3
    • These are the two small strut channels attaching the node to the long strut channel.

    • Before removing any parts, rotate the long strut channel (still attached to the node) so that it is no longer over the water.

    • 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)

  3. Depth Sensor Node Bridge Mounted Replacement Procedure, Locking the new depth sensor node: 步骤 3 中的图像 1,1
    • Obtain a new depth sensor node and attach a padlock to the new depth sensor node.

    • Projects have set lock combinations. Please ask the lab for guidance.

  4. Depth Sensor Node Bridge Mounted Replacement Procedure, Attaching the new depth sensor node to the small strut channels: 步骤 4 中的图像 1,3 Depth Sensor Node Bridge Mounted Replacement Procedure, Attaching the new depth sensor node to the small strut channels: 步骤 4 中的图像 2,3 Depth Sensor Node Bridge Mounted Replacement Procedure, Attaching the new depth sensor node to the small strut channels: 步骤 4 中的图像 3,3
    • 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 rag (if handy), clean any dirt or debris off of all screws, nuts, washers, strut channels, etc. before attaching the new 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.

  5. Depth Sensor Node Bridge Mounted Replacement Procedure, Attaching the U-brackets to the bridge mount: 步骤 5 中的图像 1,3 Depth Sensor Node Bridge Mounted Replacement Procedure, Attaching the U-brackets to the bridge mount: 步骤 5 中的图像 2,3 Depth Sensor Node Bridge Mounted Replacement Procedure, Attaching the U-brackets to the bridge mount: 步骤 5 中的图像 3,3
    • 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.

    • Once again, hold the node securely to ensure it does not fall while the U-brackets are being attached to the bridge mount.

    • This step will use the same 3/4" nuts and washers from the first step.

    • 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.

  6. Depth Sensor Node Bridge Mounted Replacement Procedure, Measure and record the distance from the bottom of the depth sensor node to the bottom of the river: 步骤 6 中的图像 1,2 Depth Sensor Node Bridge Mounted Replacement Procedure, Measure and record the distance from the bottom of the depth sensor node to the bottom of the river: 步骤 6 中的图像 2,2
    • 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.
