Measurement Methods
There are three base measurement methods:
1. Single measurement method: This method involves measuring the
thickness at a single point.
2. Double measurement method: This method involves performing two
thickness measurements near a single spot rotating the ultrasonic
sensor from 0 to 90° respectively, with respect to the split face
(Fig.1).Take the smaller of the two indicated values as the thickness
of the material.
3. Multi-point measurement: This method involves performing a number
of measurements within a circle having a maximum diameter of
about 1.18" (30mm). Take the minimum indicated value as the
thickness of the material.
