Application of Clamp-On Ultrasonic Flowmeter for Industrial Flow Measurements
Flow Measurement and Instrumentation, 1994Abstract The development and testing results of a newly designed clamp-on transit time ultrasonic flowmeter are presented. The microprocessor-based flowmeter was tested on steel pipelines of diameters ranging from 40 mm to 300 mm in some water plants and in the calibration station. The results of calibration have proved that the nonlinearity error of

Application of a Portable Clamp-On Ultrasonic Flowmeter in the Water Industry
Flow Measurement and Instrumentation, 1994Abstract This paper illustrates the experimental results obtained in a volume flow rate measurement application performed in the water industry. A clamp-on (transit time) portable ultrasonic flowmeter is compared to an in-line (or wetted) electromagnetic meter (used as a master meter). Both meters are mounted in series along a long stretch of pipe in

Feasibility Study on Clamp-on Ultrasonic Flowmeter Based on EMAT
JOURNAL OF THE KOREAN SOCIETY FOR NONDESTRUCTIVE TESTING, 2018건식 초음파 유량계는 기존 배관설비를 변경하지 않고 유량이 측정 가능하므로 산업현장에서 많은 주목을 받고 있다. 하지만 기존 건식 초음파 유량계는 압전 방식의 초음파 변환을 이용하므로 배관-유량계 접촉 문제, 낮은 신호대잡음비, 협소한 적용 온도 구간 등의 한계를 지니고 있다. 본 연구에서는 압전 원리 대신 전자기음향변환원리를 이용한 초음파 유량계를 제안하고 전자기 음향 트랜스듀서 적용에 따른 시간차법을 이용한 유량산출 모델을 제시하였다.

Ultrasonic Transducer Positioning System for Clamp-On Flowmeter Applications
2016 IEEE Sensors Applications Symposium (SAS), 2016The positions of the ultrasonic transducers of clamp-on flowmeters have a determining influence on the precision and the accuracy of the measurement results. In this paper a transducer positioning system for ultrasonic clamp-on sensor applications is presented. It was designed in result of studies of the sensitivity and works automatically.
