Function and system design. . . . . . . . . . . . . . . . . . . . . 3
Measuring principleVortex meters work on the principle of the Karman vortex street. When luid flows past a bluff body, vortices
are alternately formed on both sides with opposite directions of rotation. These vortices each generate a local
low pressure. The pressure fluctuations are recorded by the sensor and converted to electrical pulses.
The vortices develop very regularly within the permitted application limits of the device.
Therefore, the frequency of vortex shedding is proportional to the volume flow.
v
A0003938
The K-factor is used as the proportional constant:
K-Factor =
Pulses
Unit Volume [dm³]
A0003939-EN
Within the application limits of the device, the K-factor only depends on the geometry of the device. It is
independent of the fluid velocity and the fluid properties viscosity and density. In this way, the K-factor is also
independent of the type of matter that is to be measured, regardless of whether this is steam, gas or liquid.
The primary measuring signal is already digital (frequency signal) and linear to the flow.
After production, the K-factor is determined in the factory by means of calibration and is not subject to longtime or zero-point drift.
The device does not contain any moving parts and does not require maintenance.

The capacitive sensor
The sensor of a vortex flowmeter has a major influence on the ability, robustness and reliability of the whole
measuring system.
The robust DSC sensor - with an integrated temperature sensor (Pt 1000) with Prowirl 73 - is burst-tested and
vibration and temperature-shock-tested (temperature shocks of 150 K/s).
The Prowirl uses the tried-and-tested capacitive measuring technology of Endress+Hauser applied in over
100,000 vortex measuring points worldwide.
The DSC sensor (Differential Switched Capacitance) patented by Endress+Hauser has complete mechanical
balancing. It only reacts to the measured variable (vortex), not to vibrations. Even in the event of pipe
vibrations, the smallest of flows can be reliably measured at low density thanks to the unimpaired sensitivity of
the sensor.
Thus, the wide turndown is also maintained even in the event of harsh operating conditions. Vibrations up to
1 g, in frequencies up to 500 Hz in every axis (X, Y, Z), do not affect the flow measurement.
Thanks to its design, the capacitive sensor is also particularly mechanically resistant to temperature shocks and
water hammer in steam lines.

Temperature measurement (Prowirl 73)
In addition to the volume flow, the measuring device also measures the fluid temperature.
The temperature is measured by means of a Pt 1000 temperature sensor which is located in the paddle of the
DSC sensor, i.e. directly in the fluid (Fig. Pt 1000).
Flow computer (Prowirl 73)
The electronics of the measuring device have an integral flow computer. With the aid of this flow computer
other process variables can be calculated from the primary measured variables (volume flow and temperature),
e.g.:
• The mass flow and heat flow of saturated steam and water in accordance with IAPWS-IF97/ASME
• The mass flow and heat flow of superheated steam (at constant pressure or pressure read in via HART/
PROFIBUS PA/FOUNDATION Fieldbus) in accordance with IAPWS-IF97/ASME
• The mass flow and corrected volume flow of other gases (at a constant pressure or pressure read in via
HART/PROFIBUS PA/FOUNDATION Fieldbus, e.g. compressed air or optional natural gas AGA NX-19)
• The mass flow of any liquid (linear equation)
• Delta heat between saturated steam and condensate (second temperature read in via HART) in accordance
with IAPWS-IF97/ASME
• Delta heat between warm water and cold water (second temperature read in via HART) in accordance with
IAPWS-IF97/ASME
• In saturated steam measurements, the pressure of the steam can also be calculated from the measured
temperature and output in accordance with IAPWS-IF97/ASME

Diagnostic options (Prowirl 73)
Extensive diagnostic options, such as retracing fluid and ambient temperatures, extreme flows etc., are also
optionally available for the measuring device.

Influence of ambiente temperature
If all the configurable functions for filter times (flow damping, display damping, current output time constant,
frequency output time constant, status output time constant) are set to 0, a reaction time/step response time
of 200 ms must be reckoned with for vortex frequencies as of 10 Hz.
For other settings, a reaction time/step response time of 100 ms must always be added to the total filter
reaction time for vortex frequencies as of 10 Hz.
Current output (additional error, in reference to the span of 16 mA):
• Zero point (4 mA):

• Span (20 mA):
average Tk: 0.05%/10 K, max. 0.6% over the entire temperature range –40 °C ... +80 °C
Digital outputs (pulse output, PFM, HART, frequency output (Prowirl 73 only))

Operating conditions: installation
Installation instructionsVortex 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, there should be upward flow in vertical pipes to avoid partial pipe filling (see orientation
A).
In the case of hot media (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 media (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 orientations.
Caution!
• If fluid temperature is ≥ 200 °C, orientation B is not permitted for the wafer version
(Prowirl 72W, 73W) with a nominal diameter of DN 100 and DN 150.
• To guarantee the flow measurement of liquids, the measuring tube must always be completely full in pipes
with vertical downward flow.

Minimum spacing and cable length
To ensure problem-free access to the measuring device for service purposes, we recommend you observe the
following dimensions:
• Minimum spacing in all directions = 100 mm (A)
• Necessary cable length L + 150 mm
