Endress+Hauser Prowirl F 200 Vortex Flowmeter

Overview of the Endress+Hauser Prowirl F 200

The Endress+Hauser Prowirl F 200 is a flanged vortex flowmeter from the Proline 200 family, designed for saturated, superheated and wet steam, gases and liquids, including cryogenic fluids. It is offered in nominal diameters from DN 15 to 300 (½ to 12 in) and combines a robust, drift-free capacitive sensor with a dual-compartment transmitter housing. According to Technical Information TI01333D, the measuring principle complies with the international vortex standard ISO 12764, the meter body keeps the same accuracy down to a Reynolds number of 10,000, and wet steam detection is available for DN 25 to 300.

Seven Star LLC supplies the Endress+Hauser Prowirl F 200 to power plants, refineries, petrochemical units and utility contractors across the Sultanate of Oman and the GCC, with engineering support in Muscat. The meter is a frequent choice for steam distribution and boiler house metering, where integrated temperature and pressure measurement turns one instrument into a complete energy measuring point.

Measuring Principle of the Endress+Hauser Prowirl F 200

The Endress+Hauser Prowirl F 200 works on the principle of the Karman vortex street. When fluid flows past a bluff body in the measuring tube, vortices form alternately on both sides with opposite directions of rotation, each generating a local low pressure. A DSC capacitance sensor records these pressure fluctuations and converts them into electrical pulses. Within the application limits, vortex shedding frequency is proportional to volume flow, and the factory-calibrated K-factor depends only on the meter geometry, so above Re 10,000 it is independent of flow velocity, viscosity, density and of whether the medium is steam, gas or liquid.

The sensor has been burst-tested and tested against vibration and against thermal shocks of 150 K/s, and the capacitance technology is in use at more than 450,000 measuring points. There are no moving parts and no maintenance requirement, and the K-factor is not subject to long-term or zero-point drift. Endress+Hauser describes this as lifelong calibration in non-abrasive and non-corrosive media such as most water and steam applications, provided edge wear on the bluff body stays below 1 mm.

Engineering Design of the Endress+Hauser Prowirl F 200

Measuring tubes are made of stainless cast steel CF3M/1.4408, with cast Alloy C22 equivalent available for DN 15 to 150, and flanges are triple-certified 1.4404/F316/F316L to EN, ASME and JIS standards from PN 10 to PN 100 and Class 150 to 600, compliant with NACE MR0175 and MR0103. Sensor versions cover volume measurement from –40 to +260 °C, a high-temperature version from –200 to +400 °C, a mass version with Pt1000 temperature measurement in the sensor paddle, and mass steam or mass gas/liquid versions with an integrated pressure cell and industrial siphon. Seals include graphite, FPM, Kalrez and Gylon.

The Proline 200 transmitter is available in compact or remote form with aluminium or stainless CF3M housing rated IP66/67, Type 4X. Outputs include passive 4–20 mA HART, a second 4–20 mA, pulse, frequency and switch output, PROFIBUS PA, FOUNDATION Fieldbus, and PROFINET or Modbus TCP over Ethernet-APL. A four-line illuminated display with touch control lets the Endress+Hauser Prowirl F 200 be configured without opening the housing, and Heartbeat Technology provides integrated verification.

Key Features of the Endress+Hauser Prowirl F 200

The following points from TI01333D summarise the strengths of the Endress+Hauser Prowirl F 200:

• Volume flow measurement error below 0.75 % o.r. for liquids and below 1.0 % o.r. for gases and steam, or 0.65 % and 0.9 % with the PremiumCal 5-point calibration.
• Integrated temperature and pressure measurement for density and energy compensation of steam and gases.
• Wet steam detection and steam quality output for DN 25 to 300.
• Inlet run correction that shortens the required straight inlet to 10 × DN after elbows or reductions, with an additional error of ±0.5 % o.r.
• Typical operable flow range up to 49:1, with medium temperatures from –200 to +400 °C depending on the sensor version.
• Calculation of corrected volume, mass, energy and heat flow difference for steam, water, air and industrial gases.
• Use in flow monitoring systems up to SIL 2 in single-channel and SIL 3 in redundant architecture to IEC 61508.
• Heartbeat Technology for verification in operation, plus worldwide hazardous area approvals.

Industrial Applications of the Endress+Hauser Prowirl F 200

The Endress+Hauser Prowirl F 200 is used for steam generation and distribution, boiler efficiency monitoring, energy billing between plant areas, fuel gas and compressed air metering, nitrogen and other industrial gases, and liquids such as condensate, demineralised water and thermal oil. In Oman these duties are found in power and desalination plants, refinery steam networks in Sohar, petrochemical and fertiliser complexes, food and beverage factories with steam utilities in Rusayl and Salalah, and district utility systems.

Seven Star LLC supplies the meter sized to the actual process data, together with seals and certificates required by the project. For related flow tasks, buyers can review the earlier Endress+Hauser Prowirl 72F, the Promass F300 Coriolis mass flowmeter for direct mass measurement of liquids, or the t-mass 65F thermal mass flowmeter for gases.
