3-6
Coefficient A is an additive offset value to correct the Measured
Velocity for any additive bias. The value for A must be expressed
in units of meters/second. The default is “0”.
Coefficient B is a multiplicative scalar for correcting the Mea-
sured Velocity for any linear multiplicative bias. The value for B
is unitless. The default is “0.9”.
Coefficient C is another scalar to correct the Measured Velocity
for any nonlinear bias. The value for C must be expressed in
units of seconds/meter, so that the resulting value for the
Reported Velocity Reading will be in units of meters/second. The
default is “0”.
Spectral Averages – The value for Spectral Averages may be
used to reduce noise and improve signal strength. The default is
“5000”. If persistent low signal strength or velocity dropouts are
indicated, enter a high value, such as 10000. If signal quality and
measurement improve, try entering a lower value, such as 7500,
observing the signal quality. The lower the value for Spectral
Average, the less time required for each complete measurement,
reducing power usage. Adjust the value to determine a number
that balances power usage with satisfactory signal quality and
readings.
Re-home Count – For testing purposes only. For more infor-
mation, contact Environmental Products Support.
Peak Detect – The Peak Detect function scans across the
user-defined row to locate the peak velocity. To enable Peak
Detect functionality, select the “
Peak Detect ” box.
Adaptive Focus – Adaptive Focus enab les the LaserFlow
module to scan above and below the standard focus point, then
adjust the focus to the point with the best signal strength. To
enable Adaptive Focus functionality, select the “
Adaptive
Focus ” box.
Positive Downstream – Select the “ Positive Downstream ”
box when the LaserFlow sensor is pointed downstream.
Maximum Distance – The Maximum Distance is the greatest
distance (e.g., inches) the LaserFlow sensor will take a direc-
tional velocity reading. The default is “48”. Units of mea-
surement are based on user settings.
Maximum Velocity – The Maximum Velocity is the greatest
velocity (e.g., ft/s) the LaserFlow sensor will take a directional
velocity reading. The default is “1”. Units of measurement are
based on user settings.
Steep Slope LaserFlow Focusing – If the pipe is on a slope
greater than 1%, select the “ Enable Slope Setting ” box. By
default, this option is disabled.
Parallel to Channel Slope – If the sensor is parallel to the
channel slope, select “ Parallel to Channel Slope ”. Measure
from the front of the sensor carrier to the bottom of the channel.
Then measure from the back of the sensor carrier to the bottom
of the channel. Ensure the distance is equal. Adjust the sensor
