Inspecting, Cleaning, and Handling the
Sensors
Perform the following sensor inspections during regular site visits:

Verify that the installation ring or bands are secure and clear of
debris.

Clean the face of the Surface Combo Sensor/Ultrasonic Depth
Sensor gently with a soft brush, and wipe the sensor with a
clean, moist cloth.
Note:
The crystals on the Surface Combo Sensor are
covered with a Teflon
®
coating. Therefore, do not use a
wire brush or other abrasive, metallic device to clean these
sensors.

Verify that the face of the Surface Combo Sensor/Ultrasonic
Depth Sensor is horizontally level with the flow. If necessary,
reposition the sensor according to the procedures in
Chapter 3 ,
Sensor Installation and Connection .

Scrub the face of the Peak Combo Sensor with a soft bristle
brush.

Confirm that all sensor cables are neatly arranged, securely
fastened, and free of debris, cuts, kinks, and breaks that may
affect performance. Replace any sensor that has a damaged
cable.
When handling, storing, or packing the Surface Combo Sensor,
avoid contacting the metal cable connector with the crystals on the
sensor. This could damage the Teflon coating covering the crystals.
Replacing the Pressure Depth Sensor Dryer Tube
or Desiccant
All combo sensors with a pressure depth sensor include a pressure
depth sensor dryer tube. This tube contains desiccant that absorbs
the moisture from the air traveling through the dryer tube into the
clear plastic tubing leading to the pressure depth sensor in the pipe.
