Development of a novel profile measurement system for actively planed surfaces

This paper presents an acoustic position measurement system used for precise three-dimensional flowline profile measurement. The system measures several points along the flowline using the long-baseline measurement technique and augments this measurement with depth telemetry repeaters to maintain elevation accuracy throughout the changing installation geometry. The paper discusses both the measurement system and the performance enhancement features. The paper concludes with a discussion of the hardware configuration and the accuracy that can be expected when the technique is extended into deeper operating areas.

Processing Software

A three-dimensional profile measurement system based on a projection coded grating technique is presented. The system uses a designing and decoding technique for grey coded gratings. The coded grating has black, white and grey stripes. The period triples a conventional grating. It greatly increases the height measuring range without any decrease in stripe separation. The shape of object can be obtained from only one grating image. The system is suitable for instantaneous measurement of moving objects including human face. The technique proposed permits rapid 3D measurement and no moving parts are involved in the system. The hardware is relatively simple. Special data processing software is developed. Results of a practical example confirm the effectiveness of the proposed method.

Velocity Profile Measurement

A new ultrasonic velocity profile measurement system with a phased array sensor was developed for accurate flow rate measurements. This measurement system employs phased array technique to reduce noise from multiple reflections which occurs in a wedge. However, phased array technique has some difficulties — one of them is about grading lobes. Thus, the array sensor was designed to reduce the grading lobes using simple calculations. Performance of the manufactured array sensor was evaluated by experimental measurements of sound pressure distribution emitted from the array sensor, and optimal parameters to control the array sensor were obtained. Hardware and software of the ultrasonic velocity profile measurement system with a phased array sensor were also developed. The software is based on ultrasonic Doppler method. Velocity profiles of horizontal pipe flow were measured using the developed system, and the availability of the system applying a phased array sensor was confirmed.
