Abstract

A radiometer for use in ultrasonic power measurements in the 10–200 milliwatt regime has been built and tested. The device is based on the torque feedback principle applied to a friction‐free taut‐band meter movement. Measurements using the instrument have been made on two commerical ultrasound instruments.
