Ultrasonic Measurement Devices

RPC has been involved in development of ultrasonic devices for more than 20 years. The concentration of our research has been driven by industry demand for very accurate on-line, real-time measurement of station parameters such as flow, temperature and pipe wall thickness. The devices RPC has designed and built are based on the contra-propagating transit-time technique and employ the concept of virtual instrumentation technology to integrate various hardware and software components in one operating system. RPC developed its proprietary DSP procedures to measure the time difference with a picosecond precision. As a consequence, in standard conditions, the flow and thickness can be measured with a resolution better than ±1 mm/s and 0.1 µm, respectively. The devices developed at RPC are enclosed within industrial PC computers and work under the Windows XP operating system. In high temperature (HT) applications, RPC devices work in conjunction with the high temperature ultrasonic transducers manufactured by our Japanese partner. The transducers enable continuous monitoring of flow and/or thickness at temperatures up to 500 °C.
