Squirters are a variant or immersion testing. They use columns of pressurized water for coupling.
- In the case of through transmission squirters, a squirter is positioned on each side of the plate
- A probe is inserted in each squirter
- Pressurized water is supplied to the squirters
- Ultrasound waves can travel from the transmitter probe to the receiver probe
Positioned by automated robotic arms according to a pre-set pattern, squirters can inspect complex shapes.
