美国Ohmic UPM-DT-50SP超声功率计，50 mW分辨率
测量超声功率的最可靠和可重复的手段是通过辐射力法。要测试的传感器位于45°空气锥形目标上方的脱气水中。该联轴器是用精度达到±0.15瓦的精密天平。当声能施加到锥体时，合力与总辐射功率成正比。测试箱内衬声波吸收橡胶以防止声反射。天平被编程为将毫克量级的力直接转换为具有良好分辨率的以瓦特为单位的读数。功率计的测量精度可以通过在锥体的支撑臂上放置校准的重量来验证。

The most reliable and repeatable means of measuring ultrasound power is by the radiation force method. The transducer to be tested is centered above a 45° air-backed cone target in de-gassed water. The coupling is made to a precision balance capable of resolving ± 0.15 watts. When acoustic energy is applied to the cone, the resultant force is directly proportional to the total radiated power. The test tank is lined with sonic absorbent rubber to prevent acoustic reflection. The balance is programmed to convert milligram magnitude forces direct to a readout in watts with good resolution. Measurement accuracy of the power meter can be verified by placing a calibrated weight on the cone’s support arm.
