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 new Surface Combo Sensor
(available late 2012) 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.
