Installation effects on performance of ultrasonic cross correlation flowmeters
- Korea Research Inst. of Standards and Science, Taejon (Korea, Republic of)
A cross correlation flowmeter having DSP correlator has been developed at KRISS. Since the new correlator has a relatively high s/n ratio, this flowmeter can be used by applying wet method as well as clamp-on method. Before testing the installation effects, baseline of the flowmeter was determined by evaluating the performance under the reference flow conditions which may be described as fully developed. Distortion of the velocity profile was produced by passing the reference flow into the single elbow, double elbows out-of-plane, double elbows in-plane, or a partially open gate valve. Up to 7% of deviation from the baseline data has been observed depending upon disturbance sources or installation location of ultrasonic transducers.
