Flow meter withstands corrosion in harsh environments

October 29, 2008

The new V-Cone® Flow Meter is designed for high accuracy measurement with virtually no maintenance and long life under the most challenging conditions, according to the manufacturer. Prolonged equipment exposure to water, acids, fuels, solvents, high temperatures and high pressures creates a constant corrosion problem in many process industry plants. Ammonia, chlorine, cyanide, hydrochloric acid, hydrogen sulfide, methane and other harsh substances cause corrosion that requires extra maintenance or reduces the life of instrumentation, pumps, valves and piping. Corrosion-related maintenance activity shrinks plant product throughput and increases operating costs. The V-Cone Flow Meter not only provides precise flow measurement in liquid, steam or gas media, but it also requires virtually no maintenance in the most demanding processes where corrosive conditions exist. It is ideal for use in a wide range of industries that include chemical, electric power generation, food/beverage, oil/gas production and refining, pharmaceutical, pulp/paper and more. The design of the V-Cone Flow Meter is based on advanced differential pressure technology and requires no-moving parts, which may break due to corrosion or clog during use. Built-in flow conditioning allows the V-Cone Flow Meter to achieve measurement accuracy of +0.5%, with a repeatability of +0.1. It operates over a flow range of 10:1 and services line sizes from 0.5 to 120 inches.
