Benchmarking on the Accuracy of Multiple Clamp-On Transit-Time Ultrasonic Flowmeters
2021 IEEE International Ultrasonics Symposium (IUS), 2021Clamp-on ultrasonic flowmeters became very popular in the industrial applications and they represent an interesting alternative to conventional flowmeters especially if the pipes cannot be modified or the process easily stopped. This work presents a study on the accuracy of seven clamp-on transit-time ultrasonic flowmeters coming from seven different ...

Improving interference immunity of ultrasonic gas flowmeters with clamp-on probes
Automation and Remote Control, 2013The possibility of detecting a weak desired signal passed through gas among signals propagating in the pipe wall when sounding the flow with clamp-on probes is demonstrated. The possibility of applying this method to measurement of gas flow rate in large-size pipelines is also shown.

Studies of the Accuracy of Clamp-on Transit Time Ultrasonic Flowmeters
2008 IEEE Instrumentation and Measurement Technology Conference, 2008The uncertainty of transit time ultrasonic clamp-on flowmeters is relatively high (currently approximately plusmn5% (Sanderson et al., 2002)). We have studied several factors contributing to this uncertainty, focusing mainly on the separation distance between the transducers.

Further Studies of the Accuracy of Clamp-on Transit-Time Ultrasonic Flowmeters for Liquids
IEEE Transactions on Instrumentation and Measurement, 2009The higher value of uncertainty in the flow measurement signal from transit-time clamp-on ultrasonic flowmeters (USFMs) compared with transit-time spool-piece USFMs is due to several factors, some of which have been considered in this paper. However, the main focus of this paper has been on the effect of separation distance between the transducers on ...

2017 IEEE International Ultrasonics Symposium (IUS), 2017
Clamp-on ultrasonic flowmeters geometry includes four different materials in the ultrasound propagation path: wedge, coupling material, pipe and liquid. In this case, oblique incidence ultrasonic beam generated by the emitter transducer is split into several paths caused by multiple reflections in pipe wall or because of propagation mode conversion at ...

Deviation Characteristics of Clamp-on Type Ultrasonic Flowmeter Installed in Downstream of Valves
Journal of Fluid Machinery, 2012This study was performed to found out the deviations for clamp-on type ultrasonic flowmeter installed in downstream of valves. It was selected three types of two-path flowmeter mainly used for K-water as test. Experiment carried out to confirmed characteristics of deviation depending on the sensor location, straight pipe length and maker for 1-path, 2 ...
