Frequently Asked Questions (FAQ)

1. What is the main difference between the Prowirl 72F, 73F, 7F2b, and 7F2c?

1. 72F: Standard vortex flowmeter for universal applications.
2. 73F: Adds integrated temperature measurement and energy calculation.
3. 7F2b: Includes ultrasonic diagnostics for predictive maintenance.
4. 7F2c: Advanced ultrasonic monitoring with multi-variable integration (flow, temperature, pressure).

2. Which media can be measured with these flowmeters?

They are suitable for steam, gases, and liquids, including saturated and superheated steam, compressed air, natural gas, water, and process fluids.

3. How does ultrasonic technology improve vortex measurement?

Ultrasonic diagnostics continuously monitor sensor health, vibration, and process stability. This ensures long-term accuracy, predictive maintenance, and higher reliability in critical applications.

4. What communication protocols are supported?

Depending on the model, the Prowirl series supports:

1. 4–20 mA HART
2. Pulse / Status outputs
3. FOUNDATION Fieldbus
4. PROFIBUS PA
5. Modbus (7F2c)

5. Can these flowmeters calculate energy consumption?

Yes. Models 73F, 7F2b, and 7F2c can calculate mass flow, corrected volume flow, and energy consumption when measuring steam or gases, making them ideal for energy management systems.

6. What industries typically use the Prowirl series?

1. Power generation (steam monitoring, district heating)
2. Chemical and petrochemical (process gases, solvents)
3. Oil & Gas (steam, flare gas, custody transfer)
4. Pharmaceutical and food (liquids, utilities)
5. General industry (compressed air, energy efficiency)

7. How is installation handled?

The Prowirl series is designed for flanged, wafer, or sandwich mounting. Installation requires straight inlet/outlet pipe runs for optimal accuracy, and the flow direction is clearly marked on the body.

8. What maintenance is required?

Minimal. The robust stainless-steel design and ultrasonic diagnostics reduce the need for manual checks. Predictive maintenance alerts help schedule service before failures occur.

9. Are these flowmeters suitable for custody transfer?

Yes, higher-end models (73F, 7F2b, 7F2c) with advanced diagnostics and digital communication can be used for allocation measurement and billing in compliance with industry standards.

10. What sizes are available?

The Prowirl series covers a wide range of nominal diameters (DN15 to DN300 and above), making it adaptable for small pipelines and large industrial systems.
