Proline Prowirl 72F, 72W, 73F, 73W Vort
Vortex flow measuring system
Reliable flow measurement of gas, steam and liquids
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, other gases and liquids can also be
calculated with the aid of integrated temperature
measurement and by reading in external pressure values
(Prowirl 73).
Maximum range of applications thanks to:
• Fluid temperature range from –200 to +400 °C
(–328 to +752 °F)
• Pressure ratings up to PN 250/Class 1500
• Sensor with integrated (optional) diameter reduction
by one line size (R Style) or two line sizes (S Style)
• Dualsens version (optional) for redundant
measurements with two sensors and electronics
Approvals for:
• ATEX, FM, CSA, TIIS, NEPSI, IEC
• HART, PROFIBUS PA, FOUNDATION Fieldbus
• Pressure Equipment Directive, SIL 2
Your benefits
The robust Prowirl sensor, tried and tested in over
200 000 applications, offers:
• High resistance to vibrations, temperature shocks,
contaminated fluids and water hammer
• No maintenance, no moving parts, no zero-point drift
(“lifetime” calibration)
• Software initial settings save time and costs
Additional 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
• External temperature value read-in for delta heat
measurement
