The method of frequency measurement by using spectrum analysis for the frequency of output signal of turbine flow transmitter is described and its application in flow measurement of the kernel flow of the 5MW low temperature nuclear heating pile is introduced.
the authors developed a simple pulsed ultrasound cross correlation flow measurement system using the phenomenon that ultrasound waves are randomly modulated in amplitude when transmitted through flowing two-phase fluids.
The new system is completely free from the "standing wave" interference which arises when using continuous ultrasound waves and which results in the deterioration of performance of the cross correlation flow measurement system.
Agere implements fast processing traffic and slow processing traffic. They have both advantage and disadvantage. The NP4GX 1 researched has refined instruction set, support IPv4 and IPv6, flow control and management, flow measurement and control, error data correction.
The sap flow measurement was used in combination with morphological characteristics of tree and forest structure to calculate the whole-tree transpiration (E), stand transpiration (Et), and mean canopy stomatal conductance (gc).
By the turbulent flow measurement using the split-film probe, two peaks of turbulence level are observed for the strong decelerating flow case.
Performance test and flow measurement of contra-rotating axial flow pump
On the other hand, it was clarified from the flow measurement results that circumferential velocity component at the outlet of the outer rotor of contra-rotating rotors becomes larger than a conventional one.
Terahertz process tomography (PT) is a new technology for multiphase flow measurement.
