Characteristics of Flow Meters with Sediment Laden Flow ? A Review

Measurement of flow is an important aspect in the field of hydraulic engineering, both in case of open channel as well as pipe or conduits. In case of pipe conduits various flow meters are used for flow estimation; out of which venturimeter and orifice meter are most commonly used and conventional means. Pipes or conduit carrying sediment laden flow or slurry-water mixture is very common in most of the industries, sewage carrying system etc. Suitability of flow meters i.e. venturimeter and flow meter need to be analyzed for sediment laden flow. Due to the presence of slurry or sediments, coefficient of discharge of flow meter will vary. In the present paper, various works that have been carried out till now in the analysis of characteristics of venturimeter and orifice meter with sediment laden flow are described.
