Table 5 Configuration options—US900X ultrasonic sensor
Option Description
Basic Settings
Sensor Type Selects the sensor type. Options: Downlooking or In-Pipe.
Sediment Enters the level of sediment in the bottom of the channel. Options: 0.00 to 0.30 m (0.00 to
12.00 in.).
Level Offset
(optional)
Enters the difference between the measured level and the actual level. Options: –0.61 to
0.61 m (–24.00 to 24.00 in.). Use Level Offset to correct an offset error without having to do
a calibration.
Adjust Level Completes a distance measurement to use for level adjust.
Flow Settings
Device Selects the primary device. Enters the device specifications. Refer to Table 7.
Application Settings
Filter Size Selects the number of readings the sampler does and averages for one data point. Options:
1 to 50 (default: 16).
Reject High Selects the number of the highest values that are discarded. Options: 0 to 49 (default: 4).
For example, if the filter size is 16 and the reject high and reject low values are 4, the
sensor collects 16 measurements and discards the highest 4 and the lowest
4 measurements. The other 8 values are used to calculate the average data point of level.
Reject Low Select the number of the lowest values that are discarded. Options: 1 to 49 (default: 4).
Number of Holds Selects the number of times the last recorded data point is saved to the log if a failed
reading occurs due to echo loss. Options: 0 to 15 (default: 4).
For example, if the number of holds is 5, the last data point replaces the next five
consecutive failed readings or until a successful reading occurs.
Median Filter Selects the number of data points used in the median filter. The sampler takes median of 3,
5, 7, 9 or 11 data points to decrease noise or outliers (default: None). Only the median
values are logged. Raw data values are not logged.
Advanced Settings
Sample Rate Selects the number of measurements done per second. Options: 1 to 10 (default:
4 seconds).

Max Dist Selects the maximum distance from the sensor to the water. Options: 0.13 to 3.96 m
(10.50 to 156.00 in.). Distances more than the maximum distance of the sensor are
ignored.
Profile Do not change this setting without guidance from technical support. This setting is used to
increase the performance of the sampler when the sampler is used in very difficult
conditions. Options: Free Air Low, Free Air Mid (default), Free Air High, Stilling Tube Low,
Stilling Tube Mid or Stilling Tube High.
Transmit Power Do not change this setting without guidance from technical support. This setting is used to
increase the performance of the sampler when the sampler is used in very difficult
conditions. Options: 2 to 30 (default: 10).

Advanced Settings
AV9000S Level Filter Settings—Selects the type of filter and the filter size (factory default is none). Takes the
average and/or median of 3, 5, 7, 9 or 11 data points to reduce noise or outliers. Only the
average and/or median values are logged—raw data values are not logged. A significant
delay can occur before sudden changes in flow are logged, therefore this option is not
recommended for stormwater applications. Options: None, Average, Median or Average and
Median.
AV9000S
Velocity
Neg. Vel to Zero—Enable to replace all negative velocity measurements with 0. Site
Multiplier—The value that adjusts the sensor velocity reading to be the same as the velocity
reading from a different instrument. If not sure, use the default value of 1.0. Low Level
Cutout—Forces the velocity to a substitute value when the level measurement is below a
user-specified value. The value of the substitute velocity is typically 0. The factory default is
enabled at 0.8 inches. Filter Settings—Selects the type of filter and the filter size (factory
default is none). Takes the average and/or median of 3, 5, 7, 9 or 11 data points to reduce
noise or outliers. Only the average and/or median values are logged—raw data values are not
logged. A significant delay can occur before sudden changes in flow are logged, therefore this
option is not recommended for stormwater applications. Options: None, Average, Median or
Average and Median.
