This paper presents the fabrication and testing of a simple and portable viscometer for the measurement of bulk viscosity of different Newtonian fluids. It is aimed at making available the instrument in local markets and consequently reducing or eliminating the prohibitive cost of importation. The method employed is the use of a D.C motor to rotate a disc having holes for infra-red light to pas...
A plasma based wakefield acceleration (PWFA) experiment, scheduled to run this summer, will accelerate parts of a 28.5 GeV bunch from the SLAC linac by up to 1 GeV over a length of 1 meter. A single 28.5 GeV bunch will both induce the wakefields in the one meter long plasma and witness the resulting acceleration fields. The experiment will explore and further develop the techniques that are nee...
Measurement in science has a long tradition as described by Lemmerich /LEMM88/. While the measurement of length the meter was defined in 1889 /LEMM88/, p.87, the measurement of temperature was more complicated. The graduation of the distance of the fixpoints was introduced by Fahrenheit in 1714 and by Celsius in 1742. Celsius devided the scale of 100 degrees and 0 degrees in hundred equal secto...
In order to improve the feasibility of low-elevation height measurement for meter-wave multiple-input multiple-output (MIMO) radar, a virtual sub-array-level beam splitting algorithm is proposed. The can solve coherence problems caused by low-angle multipath reflection, target reflection wave and direct coupling, quickly measure low elevation angle on flat ground, then obtain through geometric ...
To overcome the shortcoming that the traditional frequency measurement method does not meet the requirement of equal precision, a design method of equal precision frequency meter based on FPGA is proposed. The system modules are all realized in Altera’s FPGA chip EP2C35F672C8. Experimental results show that the system can measure frequencies with equal precision in the whole frequency range, an...
Abstrac tThis paper is focused on the problem of the metrological characterization of multifunction static meters based on integrated devices, in both reference and actual operating conditions. The influence of the measurement transducers on the performance of such meters is also discussed. The analysis is supported by some experimental tests, which were carried out on a meter based on a commer...
Many factors influence the quality of turbine meter flow measurement. Recognizing these factors allows a user to optimize the flow measurement performance of a turbine metering system. In order to ensure that turbine meters in the field are operating at their best, turbine metering stations must be properly designed, calibrated, installed, and maintained on a regular basis. This paper explains ...
