TIENet™ 360 LaserFlow™ Velocity Sensor
Section 3 Setup with Signature® Flow Meter
3.2.6 350 Advanced Settings
The LaserFlow Advanced Settings are pre-programmed into
(Optional)
the sensor. However, if your application requires any custom con-
figuration, the Advanced button opens the Advanced settings
window (refer to Figure 3-5).
Input Velocity Coefficients – The relationship of the three
Input Velocity Coefficients A, B and C can be expressed as:
2
V = A (offset) + B*(Measured Velocity) + C*(Measured Velocity)
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".
The sensor is pre-programmed at the factory with the Advanced
Settings for your application. Should your application require
the addition of any correction factors, the Advanced button opens
the Advanced settings window (Figure 3-8).
Input velocity coefficients can be adjusted for A, B, and C, where:
2
V = A (offset) + BV (slope) + CV
(second-order parameter).
