Liquids Water Gas Steam Flowmeter E+H 7D2C 7F2C 7R2C 7O2C Proline Prowirl D200 F200 R200 O200 Endress Hauser Vortex Flow Meter
Endress+Hauser Prowirl F 200 Vortex Flowmeter
The one vortex meter that doesn’t lie when steam gets wet
Why People Buy Prowirl F 200 Instead of Cheaper Vortex Meters
Every other vortex meter on the market starts reading high or just gives up when steam quality drops below 95%. The Prowirl F 200 doesn’t care – it still reads correctly even at 100% wetness (pure water). It uses a special two-wire capacitive sensor that looks at the whole flow profile, not just one bluff body edge. Result: you get real mass flow of steam no matter how wet it is. Power plants, refineries and chemical plants have been using it for years and finally stopped arguing about “who is stealing my steam".
Things That Actually Matter on Site
- Wet steam compensation built-in – no extra pressure/temperature sensors needed
- Same sensor measures steam, gases, liquids – no range changes
- ±0.75% accuracy for liquids, ±1% for steam/gas – real numbers, not marketing
- Dual compartment housing + separate terminal box – easy wiring in the rain
- Heartbeat Technology – push one button, get a signed verification report
- Works down to Reynolds 4000 – no long straight runs needed

Questions We Get on Every Job
Q: Will it really measure 100% wet steam?
A: Yes – the capacitive sensor sees the whole flow, not just vortices.
Q: Do I need external pressure and temperature?
A: No – built-in compensation version F 200 has P and T sensors inside.
Q: How do I prove it’s still accurate?
A: Press the Heartbeat button – 30 seconds later you have a signed PDF report.
