A. Gauge Reference Point
B. Distance from gauge reference point to Verification Pin
C. Verification Pin
Note
The value entered in the Nominal Pos field refers to the mechanical distance from
the Gauge Reference Point to the actual Verification Pin. This value will only act as a
starting point for the verification process in which the electrical distance from the
Gauge Reference Point to the Verification Pin is calculated. In most cases the
electrical distance deviates from the actual mechanical distance.
6. Ensure that the Threshold value is 500 mV.
The amplitude of the echo from the Verification Pin must be above the threshold
value in order to appear in the
LPGVerify window (see Verify the gauge
measurement ). In case the Verification Pin does not show up, it is possible to use a
smaller threshold value. Check that the product level is not above the Verification
Pin.
