Correlation Algorithm, cont'd
If the transmitter is not detecting the Interface Level then adjust the Interface
Reflection parameters to match what is seen on the observed echo curve at
the Interface peak reflection. For example, suppose by zooming in on the
observed echo curve at the Interface peak reflection position, user sees the
observed Interface wave's greatest amplitude is 1200 and its observed
greatest width is 150mm at the x axis; whereas the configured Interface Gain
is 1000 and configured Interface Width is 140mm. Then user needs to change
the configured Gain to 1000 and configured Width to 140mm to match the
observed curve.
Determines the width of the Interface wave where it crosses the x axis (one
half wavelength).
Amplitude of the peak corresponding to Interface wave shape.
Increased attenuation results in smaller side lobes of the wave's shape.
If changing the gain does not help try increasing threshold.
If the Probe End point is not being found then adjust the Probe End Reflection
parameters to match the observed echo at the Probe End point location. For
example, suppose by zooming in on the observed echo curve at the Probe
End point position the user can see the observed Probe End wave's greatest
amplitude is 2000 and its observed greatest width is 90mm at the x axis;
whereas the configured Probe End Gain is 1500 and configured Probe End
Width is 70mm. This means the user needs to change the configured Gain to
2000 and configured Width to 70mm to match the observed curve. Note that
the transmitter will only attempt to find the Probe End Reflection if the surface
level is close or below the end of probe.
Determines the width of the Probe End wave where it crosses the x axis (one
half wavelength).
Amplitude of the wave shape.
Increased attenuation results in smaller side lobes of the wave's shape.
If changing the gain does not help try increasing threshold.
Determines the width of the Process Connector where it crosses the x axis
(one half wavelength).
Amplitude of the wave shape.
