Endress+Hauser Prowirl 72F Vortex Flowmeter
Overview
The Endress+Hauser Prowirl 72F is a robust and safe vortex flowmeter designed for the universal measurement of gases, steam, and liquids, suitable for safety-instrumented applications up to SIL 2. Its patented capacitive DSC sensor delivers high-precision measured values even under the toughest process conditions, including high temperature steam service and pulsating flow.
As the official authorized partner and exclusive regional representative for Endress+Hauser, Seven Star LLC proudly supplies the Endress+Hauser Prowirl 72F to power plants, process industries, and utilities across the Sultanate of Oman and the wider GCC, backed by genuine factory calibration, full documentation, and local technical support.
Measurement Principle
The Endress+Hauser Prowirl 72F operates on the vortex shedding principle. A bluff body positioned in the flow path generates alternating vortices as fluid passes, at a frequency directly proportional to flow velocity; the patented capacitive DSC sensor detects these vortices and converts the signal into an accurate volumetric flow measurement independent of fluid density or pressure changes at a given velocity.
Because vortex shedding is a well-understood, repeatable physical phenomenon, the Prowirl 72F delivers consistent accuracy across gases, steam, and liquids from a single sensor design. The instrument has no moving parts to wear in the measuring path itself, and its high-temperature rating makes it a proven choice for steam metering where mechanical meters degrade quickly.
Engineering Design of the Endress+Hauser Prowirl 72F
The sensor is available in nominal diameters from DN 15 to DN 300 (1/2 inch to 12 inch), rated for process pressures from PN 10 to PN 250 (Class 150 to 1500, JIS 10K to 40K) and medium temperatures from –200°C to +400°C, with up to +450°C available on request for specialized high-temperature steam applications.
The transmitter features a two-line liquid crystal display with push-button operation and quick setup capability, housed to IP67 (NEMA 4X) protection. The compact version operates in ambient temperatures from –40°C to +70°C, while the remote sensor version extends to +85°C, giving flexibility for installation near hot process lines.
Key Features
The Endress+Hauser Prowirl 72F is engineered for universal, high-precision flow measurement, and the Endress+Hauser Prowirl 72F is proven across steam, gas, and liquid duty in demanding industrial plants:
- Measures gases, steam, and liquids from a single vortex sensor design with a patented capacitive DSC sensor.
- Delivers measurement accuracy of ±0.75% across its rated flow range.
- Handles medium temperatures from –200°C to +400°C, with up to +450°C available on request.
- Is rated for process pressures up to PN 250 (Class 1500, JIS 40K) for high-pressure steam and gas lines.
- Is suitable for safety-instrumented systems up to SIL 2.
- Covers nominal diameters from DN 15 to DN 300 (1/2 inch to 12 inch).
- Achieves IP67 (NEMA 4X) protection with a two-line backlit display for on-site readouts.
- Offers compact or remote transmitter mounting to suit hot or vibration-prone installation points.
Industrial Applications
The Endress+Hauser Prowirl 72F is specified for steam metering in power plants and process utilities, saturated and superheated steam custody transfer, natural gas and compressed air measurement, and general liquid flow duty where a single robust instrument must cover multiple fluid types. Its wide temperature and pressure ratings also suit refinery and petrochemical steam and gas networks.
As the officially authorized partner for Endress+Hauser, Seven Star LLC distributes the Prowirl 72F to power generation and process facilities throughout Oman and the GCC, including projects in the Sohar and Salalah economic zones, district cooling plants, and refining and petrochemical complexes, supported by regional stock availability and factory-trained technical staff.

Why Choose Seven Star LLC for Endress+Hauser Vortex Flowmeters
A vortex meter rated for SIL 2 safety-instrumented duty has to be specified with the correct pressure class and temperature rating for genuinely demanding steam or high-pressure gas service, and a mismatch on a safety loop is a far more serious problem than on a simple indication point. Seven Star LLC works with your process safety and instrumentation engineers to confirm the Prowirl 72F’s pressure, temperature, and SIL configuration against your actual safety-instrumented system requirements, backed by our authorized Endress+Hauser partnership across Oman and the wider GCC. We also support power generation and petrochemical facilities in Sohar and Salalah with coordinated documentation for safety-loop commissioning and with planning compact-versus-remote transmitter mounting around hot steam lines.
