The Venturi flowmeter is based on a classical Venturi tube, an engineered primary flow element for a most efficient and accurate differential pressure (DP) flow measurement. Thanks to its design, it has an excellent resistance to wear and doesn’t require any maintenance. The service life of the Venturi element is usually equal to the one of the entire plant. It is therefore often the ideal choice in live steam applications of power plants, wet gas flow measurement in natural gas production or CO2 injection, flow measurement of hydrocarbons and LNG as well as in gas-to-liquid processes and refineries. KROHNE offers the complete flowmeter assembly with the Venturi tube, DP transmitter, valves, accessories, engineering, testing and documentation from a single source.
