The Model UPM-DT-xPA Series Ultrasound Power Meter is designed to measure the
ultrasonic power output of therapeutic transducers up to 30 Watts. The principle of
measurement is the radiant force method. The UPM-DT-xPA Series uses a positioning
clamp to hold the transducer in degassed water above a conical target. The ultrasonic
energy passes through the water to reflect off the target and is then absorbed by the
rubber lining. The radiant power is directly proportional to the total downward force
(weight) on the target. This force is then transferred through the target support assembly
to the electromechanical load cell inside the meter. The meter processes and digitizes
the data to display an accurate measurement of grams or Watts, selectable by the user.
