ULTRASONIC DEPTH SENSOR
SENSOR MOUNTING PLATE
Sliding the Ultrasonic Depth Sensor into the sensor mounting plate on the
band
12. Confirm that the sensor is still level.
13. Determine the physical offset for the Surface Combo Sensor or
the Ultrasonic Depth Sensor by measuring the distance from
the crown (top) of the pipe to the face of the sensor (horizontal
surface with the two/four ultrasonic crystals on either sensor).
This value is required when configuring the monitor using the
Profile or Qstart software. For the Surface Combo Sensor, do
not measure in reference to the the angled surface velocity or
surcharge velocity portions of the sensor.
Surcharge Mount (applies only to the
Ultrasonic Depth Sensor)
For a site that may experience surcharge conditions, mount the
Ultrasonic Depth Sensor on the manhole wall directly above the
opening of the incoming pipe. This will ensure the sensor
measures the range above the flow surface at the location the flow
enters the manhole. This method of mounting the sensor requires a
special surcharge bracket (p/n I40-0010). Mount the sensor in the
following way:
Note: Handle the Ultrasonic Depth Sensor with care, and
do not expose it to extreme temperatures for an extended
period of time. Keep the sensor in its protective
packaging until it is time for installation.
