Parameter Description
Sensor frequen‐ Desired sensor frequency for
cy path 1.
Path geometry The number of crossings the sig‐
nal makes through the pipe (Re‐
flect or direct geometry for path
1).
E.g.:
Z path = 1
V path = 2
W path = 4
Spacing offset Spacing offset (LTN) between
clamp-on sensors for path 1.
Parameter Description
Slope correc‐ Single point flow correc‐
tion factor tion applies to any flow
rate, positive or nega‐
tive.
Path 1 offset User calibrated zero off‐
set for path 1.
Calibrated delta time =
delta time + Path 1 fac‐
tory offset + Path 1 off‐
set.
Path 1 factory Factory calibrated zero
offset offset for path 1.
