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

Function and system design
Measuring principle Vortex shedding flowmeters work on the principle of the Karman vortex street. When a fluid flows past a bluff
body vortices are alternately formed and shed and each generates a local low pressure point downstream of the
bluff body. The pressure fluctuations are detected by the sensor and converted to electrical pulses (digital sig-
nal). Within the operating limits of the device the frequency of vortices generated is directly proportional to the
volume flow.
F06-7xxxxxxx-15-xx-06-xx-000
The K-factor is used as the proportional constant:
F06-7xxxxxxx-19-xx-06-en-000
Within the application limits of the device the K-factor (calibration factor) is dependant only on its mechanical
geometry and is independent of the fluid, velocity, viscosity and density. (gas, liquid or steam)
The primary measurement signal is digital (frequency signal) and a linear function of the flow. After
manufacture the K-factor is determined during a factory calibration and once derived is not subject to zero or
long term drift.
The device does not contain any moving parts and requires no maintenance.
The DSC (Differential Swit-
ched Capsitance) sensor
The measuring sensor for a vortex flowmeter has a major influence on the performance, robustness and
reliability of the whole measuring system.
The DSC sensor of the new Prowirl 73 incorporates the experience gained from an installed base of over
100.000 vortex measurement points with the benefits of an integrated temperature sensor (PT 1000).
To ensure that the DSC sensor meets the range of demands required in today’s applications it has been burst
tested to pressures in excess of 400 bar, vibrations in excess of 1g in all axes and temperature shocks of
150 K/s.
Prowirl 73 is capable of measuring low flow rates even with low density fluids and where pipe line vibrations
are present. The meter will maintain its wide turn down ratio even under conditions where vibrations of 1g
or more and frequencies up 500 Hz are experienced.
v
K-Factor = pulses
unit volume [dm³]
Due to its internal mechanical balance the DSC sensor
reads only the pressure pulses caused by the vortices and is
immune to any influence from mechanical pipe line vibra-
tions.
Thanks to its mechanical design, the capacitive sensor is
also especially resistant to temperature shocks and water
hammer in steam lines.

Temperature measurement In addition to the volume flow the instrument measures the temperature. This measurement is performed
by a resistance thermometer Pt 1000 located close to the process in the DSC sensor's paddle (s. fig. Pt 1000
→Page 2 ).
Flow computer The electronics of the measuring device is equipped with a flow computer. By means of this computer using
the primary measurands (volume flow and temperature) a variety of other process variables can be calculated,
e.g.:
• the mass and heat flow of saturated steam and water
• the mass and heat flow of superheated steam (at constant pressure)
• the mass and corrected volume flow of other gases (at constant pressure)
• the mass flow of any liquid
Diagnostics The device offers a wide variety of diagnostics, e.g. tracking of the temperature of media and ambient, as well
as extreme flow events etc.
Measuring system The measuring system consists of a sensor and a transmitter.
Two versions are available:
• Compact version: sensor and transmitter form a mechanical unit.
• Remote version: sensor is mounted separate from the transmitter.
Sensor
• Prowirl F (Flange version)
• Prowirl W (Wafer version)
Transmitter
• Prowirl 73
Input
Measured variable • Volumetric flow (volume flow)
is proportional to the frequency of vortex shedding after the bluff body.
• Temperature
can be available and used for the calculation of mass flow e.g..
The measured process variables volume flow and temperature or the calculated process variables mass flow,
heat flow or corrected volume flow can be configured as an output.
Measuring range The measuring range is dependant on the fluid and nominal diameter.
Start of measuring range
Depends on the density and the Reynolds number (Remin = 4'000, Relinear = 20'000).
The Reynolds number is dimensionless and indicates the ratio of a fluid's inertial forces to its viscous forces.
It is used to characterise the flow. The Reynolds number is calculated as follows:
F06-7xxxxxxx-19-xx-06-xx-000
Re = Reynolds number; Q = Flow; di = Internal diameter; m = Dynamic viscosity; r = Density

Measuring range for gases [m³/h or Nm³/h]
In the case of gases, the start of the measuring range depends on the density. With ideal gases, the density [ρ]
or corrected density [ρN] can be calculated using the following formulae:
F06-7xxxxxxx-19-xx-xx-en-002
The following formulae can be used to calculate the volume [Q] or corrected volume [QN] in the case of ideal
gases:

Operating conditions: installation
Installation instructions Vortex meters require a fully developed flow profile as a prerequisite for correct volume flow measurement.
For this reason, please note the following points when installing the device:
Orientation
The device can generally be installed in any position in the piping. In the case of liquids, upward flow is prefered
in vertical pipes to avoid partial pipe filling (see orientation A).
In the case of hot fluids (e.g. steam or fluid temperature ≥200 °C), select orientation C or D so that the
permitted ambient temperature of the electronics is not exceeded.
Orientations B and D are recommended for very cold fluid (e.g. liquid nitrogen).
Orientations B, C and D are possible with horizontal installation.
The arrow indicated on the device must always point in the direction of flow in all mounting orientations.
Caution!
• If fluid temperature is ≥200 °C, orientation B is not permitted for the wafer version (Prowirl 73 W)
with a nominal diameter of DN 100 and DN 150.
• In case of vertical orientation and downward flowing liquid, the piping has always to be completely filled.
A0001869
Possible orientations of the device
Minimum spacing and cable length
Rotating the electronics housing and the display
The electronics housing can be rotated continuously 360 ° on the housing support. The display unit can be
rotated in 45 ° steps. This means you can read off the display comfortably in all orientations.

When insulating, please ensure that a sufficiently large area of the housing support is exposed. The uncovered
