Authentic Endress+Hauser Prowirl O 200 (7O2B/7O2C) High-Pressure Vortex Flowmeter engineered for demanding steam, gas, and liquid applications up to Class 600/PN100. Rapid global dispatch and 2-hour technical quotation response.
Quick Selection Guidance — Who Needs the Prowirl O 200?
The Endress+Hauser Prowirl O 200 is built specifically for high-pressure steam utility engineers, offshore oil & gas contractors, and chemical plant operators measuring steam, gas, or liquids in extreme pipelines up to PN 250 (ASME Class 1500). If standard vortex flowmeters risk flange neck deformation or thermal stress under high pressure, the Prowirl O 200 delivers reinforced mechanical integrity paired with integrated real-time temperature and pressure mass compensation.
If you are specifying, replacing, or sourcing an Endress+Hauser high-pressure vortex flowmeter, this technical guide provides complete operational parameters and ordering benchmarks:

| Mechanical Construction | Heavy-wall body with reinforced neck | Standard industrial cast body | Requires thick orifice carrier & manifold |
| NACE Sour Gas Standard | Standard Compliance | Optional on specific wetted alloys | Depends on plate & flange material |
| Pressure Drop & Energy Loss | Very Low (Shedder bar design) | Very Low (Shedder bar design) | High Permanent Head Loss |
| Maintenance & Tubing | Direct Inline (No impulse lines) | Direct Inline (No impulse lines) | High Maintenance (Impulse line leaks) |
| Steam Mass Measurement | Integrated Temp & Pressure Sensor | Integrated Temp & Pressure Sensor | Requires external RTD, DP & Pressure Transmitters |
When installing a Class 1500 Prowirl O 200 on high-pressure steam headers, always ensure proper pipe anchoring on both sides of the meter. While the DSC sensor is resistant to vibrations, extreme thermal expansion in high-pressure steam lines can cause flange misalignment. We also recommend using spiral-wound gaskets with inner rings to prevent gasket intrusion into the flow stream.
