ABSTRACT:
An apparatus for detecting ultrasonic energy comprises a chamber, partially filled with a colored liquid, having two sides separated by spacing no greater than about 25 millimeters and having a transparent section allowing for visual observation of the height of the liquid therein. A method of detecting the energy level of a beam of ultrasonic energy being propagated through a fluid comprises positioning the apparatus in the fluid so that the beam of energy strikes the liquid at the surface thereof, whereby the beam generates a visible arc-shaped spray having an amplitude proportional to the energy level of the beam.
