** - Measured values of the received ultrasonic vibration signals:
Ta
– time value signal in the gate A, shown in microseconds.
Tb
– time value signal in the gate B, shown in microseconds.
Ta-b
– the difference between the time values between the signals A
and B in gate.
Aa
– value of signal amplitude in gate А.
Ab
– value of signal amplitude in gate В.
Aa-b
– the difference between the amplitudes of the signal in the A
and B gates.
Xba
– the distance from the front edge of the signal in gate А.
Xbb
– the distance from the front edge of the signal in gate В.
Xipa
– the distance from the input signal in the gate А.
Xipb
– the distance from the input signal in the gate В.
Ya
– coordinate of signal depth in the gate А.
Yb
– coordinate of signal depth in the gate В.
Ya-b
– the difference between the values of the coordinate signals
depth A and B.
Sa
– equivalent area signal in gate А.
Sb
– equivalent area signal in gate В.
La
– distance to the reflector along the beam in the gate А.
Lb - distance to the reflector along the beam in the gate
В.
dAa
– value of the signal level (dB) from the gate A to the maximum
signal.
dAb
– value of the signal level (dB) from the gate B to the maximum
signal.
La - Lb - the difference between the values of the distance to the
reflector along the beam in gates A and B.
