Technical Information
Proline Prowirl 73
Reliable Flow Measurement of Gas, Steam and Liquids.
Two-Wire Saturated Steam Mass Flowmeter.
Application
For universal volume or mass flow measurement of
steam, water (according to IAPWS-IF97 ASME), natural
gas (according to AGA NX-19), compressed air and other
liquids or gases.
Maximum application range:
• fluid temperatures from –200 to +400 °C
• pressure ratings up to PN40/Cl300 (higher pressure
ratings in preparation)
Approvals for hazardous areas:
• ATEX, FM, CSA, TIIS
Connection to all prevalent systems:
• HART, PROFIBUS PA, FOUNDATION Fieldbus
Relevant safety aspects:
• PED, SIL-1
Your benefits at a glance
Prowirl 73 offers a complete measuring point for
saturated steam or liquid mass in a single device:
mass flow is calculated from the measured variables
of volume flow and temperature in the integrated
flow computer.
For superheated steam or gas applications an external
pressure value can read in optionally, for delta heat
applications an external temperature value can be read
in.
The instrument can be ordered pre-programmed
(customer or application specific)
The Prowirl sensor is robust, reliable and proven in
more than a 100’000 applications. It offers:
• multivariable flow measurement in compact design
• high robustness against:
– vibrations (above 1 g in all axes)
– temperature shocks (>150 K/s)
– clogging fluids
– water hammer
• no maintenance, no moving parts, no zero point drift
