Prowirl
Vortex Flow Measuring System.
Reliable flow measurement of gas, steam and liquids
High resistance to
- Vibrations (over 1 g in all axes)
- Temperature shocks (> 150 K/s)
- Contaminated media
- Water hammer
Benefits
- The robust Prowirl sensor, tried and tested in over 100 000 applications offers:
- No maintenance, no moving parts, no zero-point drift («lifetime» calibration)
- Software initial settings save time and costs
Features
- 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)
Application
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:
- Drinking water
- Wastewater
- Sewage sludge
- Flow measurement up to 110000 m³/h (484315 gal/min)
- Fluid temperature up to +80 °C (+176 °F)
- Process pressures up to 40 bar (580 psi)
- Lengths in accordance with DVGW/ISO
Approvals for hazardous areas:
