Vortex Flow Measuring System
Reliable flow measurement of gas, steam and liquids

Your benefits

The robust Prowirl sensor, tried and tested in over 100 000 applications offers:

• High resistance to:
  - Vibrations (over 1 g in all axes)
  - Temperature shocks (> 150 K/s)
  - Contaminated media
  - Water hammer
• No maintenance, no moving parts, no zero-point drift ("lifetime" calibration)
• Software initial settings save time and costs

In addition, Prowirl devices offer the following possibilities:

• Complete saturated steam or liquid-mass measuring point in one single device
• Calculation of the mass flow from the measured variables volume flow and temperature in the integrated flow computer
• External pressure value read-in for superheated steam and gas applications (optional)
• External temperature value read-in for delta heat measurement (optional)

For the universal measurement of the volume flow of gases, steam and liquids.
The mass flow of steam, water (as per IAPWS-IF97 ASME), natural gas (as per AGA NX-19/AGA8-DC92 detailed method/AGA8 Gross Method 1/SGERG-88), compressed air and other gases and liquids can be measured via integrated temperature measurement and input of external pressure values (optional).

Maximum range of applications thanks to:

• Fluid temperature range from -200 to +400 °C (-328 to +752 °F)
• Pressure ratings up to PN 40/Class 300

Approvals for hazardous areas:

• ATEX, FM, CSA, TIIS, NEPSI, IEC

Connection to all common process control systems:

• HART, PROFIBUS PA, FOUNDATION Fieldbus

Relevant safety aspects:

• Pressure Equipment Directive
• SIL 1
