Technical Information
Proline Prowirl 72F, 72W, 73F, 73W
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.
With integrated T-measurement, the mass flow of steam,
water (as per IAPWS-IF97 ASME), natural gas (as per
AGA NX-19), compressed air and other gases and liquids
can be measured.
Maximum range of applications thanks to:
• Fluid temperature range from –200...+400 °C
• Pressure ratings up to PN250/Cl 1500
Approvals for hazardous areas:
• ATEX, FM, CSA, TIIS
Connection to all common process control systems:
• HART, PROFIBUS PA, FOUNDATION Fieldbus
Relevant safety aspects:
• Pressure Equipment Directive
• Up to SIL 2
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.
• 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)
