latest v cone flow meter principle for business for chemicals
V cone flow meter principle:
V cone flow meter is a patented technology that accurately measures flow over a wide range of Reynolds numbers, under all kinds of conditions and for a variety of fluids.The V-Cone flow meter is a differential pressure type flow meter.The principal theory among these is Bernoulli’s theorem for the conservation of energy in a closed pipe. This states that for a constant flow, the pressure in a pipe is inversely proportional to the square of the velocity in the pipe.The V-Cone meter features a centrally located cone inside a tube. The cone reshapes the velocity profile and creates a low-pressure area immediately downstream of itself,provides accurate, repeatable, and cost-optimized flow measurement solutions.The difference between the static line pressure and the low-pressure area is measured by two pressure sensors and used to determine the flow rate.
A v cone meter is a device that measures how much liquid or gas moves through a pipeline in a given period of time. Cone meter is ideal for upstream, midstream, and downstream applications that present a wide range of measurement challenges.By measuring flow rates, flow meters provide crucial visibility into what's flowing where, within pipes, drainage systems, and other types of infrastructure.Due to a V-Cone meter creates a smoother flow and operates at a lower differential pressure than other DP meters, it experiences low permanent pressure loss and reduces energy costs for pumping.
Advantages of V Cone Flow Meter :
Shorter installation lengths
Less pressure loss than orifice plates
Lower sensitivity than orifice plates and Venturi tubes to installation effects
Wafer versions
Effective for wet gas flow measurement applications
