Venturi flowmeter
DP flowmeter for the highest requirements of accuracy and long-term stability
- For acceptance testing, billing, reference measurement of steam, feedwater, hydrocarbons etc.
- Machined or welded and internally machined design acc. to EN ISO 5167 and ASME MFC-3M; low remaining pressure loss
- Manufacturing capability up to 48”; inhouse calibration also for applications with high Reynolds numbers
- Complete scope of supply from one source, incl. engineering, documentation, testing, calibration, valves, Venturi, process instrumentation, etc.
Overview
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.
