Current Meter Rating
A number of Instruments are in used to measure the velocity of water. Velocity of water plays an important role in hydraulics. Precise measurement of velocity is required in models as well as in field. The current meter gives the accurate results and may be used more conveniently as compare to other instruments. Bearing defects, friction and assembly defects etc. affect the rating of current meter. Hence periodized rating of current meter is necessary, so that accuracy is not affected.
The Hydraulics Research Unit–III at Hydraulics Research Station, Bahadrabad has a unique facility for rating current meters in northern India and carrying out current meter rating work for a variety of sponsors.
