In the field of industrial flow measurement,The Cologne VFM 1091 vortex flowmeter, with its unique Karman vortex principle and integrated temperature and pressure compensation design, has become a standard product for liquid, gas, and steam flow monitoring.Its core advantage lies in breaking through the limitations of traditional instruments on the conductivity of media, and can simultaneously meet the precise measurement needs of conductive and non-conductive media, covering abnormal working conditions from -196 ℃ to+430 ℃. It is widely used in industries such as petrochemicals, power energy, food and pharmaceuticals.

　　1、 Full medium compatibility: from conductive liquids to non-conductive gases

The VFM 1091 Cologne vortex flowmeter adopts the Karman vortex principle to measure flow rate by detecting the frequency signal generated by vortex generators in the fluid. This characteristic allows it to accurately measure conductive liquids such as water and oil, as well as non-conductive media such as air, natural gas, and steam, without relying on the conductivity of the medium.

　　2、 Integrated temperature and pressure compensation: improving steam measurement accuracy

For media with drastic changes in working conditions such as steam, this instrument innovatively integrates temperature and pressure sensors to form a "flow+temperature+pressure" three parameter measurement system.

　　3、 Explosion proof and corrosion-resistant design: ensuring safety in hazardous environments

The Cologne vortex flowmeter offers two configurations: explosion-proof and non explosion-proof. The explosion-proof model is certified by NEPSI and meets the Exib II CT2-T6 standard, making it safe for use in explosive gas environments. The contact medium part is made of 316L stainless steel and Hastelloy alloy material. In a chlorine gas transmission pipeline of a coastal chemical enterprise, the Hastelloy alloy sensor successfully resisted chloride ion corrosion and operated continuously for 5 years without performance degradation, extending the service life of traditional carbon steel instruments by 4 times.

　　4、 Intelligent diagnosis and modular structure: reducing operation and maintenance costs

This instrument is equipped with self diagnostic function, which can monitor sensor status, signal quality, and environmental parameters in real time. Its modular design supports various installation methods such as flange type, clamping type, and insertion type. In the renovation of a blast furnace gas pipeline in a certain steel enterprise, an insertion type probe was used to achieve non-stop installation, saving 40% of engineering costs.

From measuring liquefied natural gas in extremely cold regions to monitoring high-temperature and high-pressure steam, the Cologne vortex flowmeter redefines the technical standards for industrial flow measurement with full medium compatibility, high-precision temperature and pressure compensation, and intelligent operation and maintenance design. The feature of "one table for multiple uses" not only simplifies the process flow, but also creates significant economic benefits for enterprises by reducing equipment procurement and maintenance costs.
