Function and system design
Measuring principle The measuring system uses a measurement method based on the transit time difference. In this
measurement method, acoustic signals (ultrasonic) are transmitted between two sensors. Signal
transmission is bidirectional, i.e. the sensor operates as both a sound transmitter and a sound
receiver.
As the speed of propagation of the sound waves is slower against the flow direction than in the flow
direction, this results in a transit time difference. This transit time difference is directly proportional
to the flow velocity.
The measuring system calculates the volume flow of the medium from the measured transit time
difference and the pipe cross-sectional area. The sound velocity of the medium is simultaneously
measured along with the transit time difference. With this additional measured variable, it is
possible to differentiate between different media or monitor the medium quality.

Measuring system The measuring system consists of a transmitter and two or one sensor sets. The transmitter and
sensor sets are mounted in physically separate locations. They are interconnected by sensor cables.
The sensors function as sound generators and sound receivers. Depending on the application and
version, the sensors can be arranged for measurement via 1, 2, 3 or 4 traverses →  6.
The transmitter serves to control the sensor sets, to prepare, process and evaluate the measuring
signals, and to convert the signals to the desired output variable.

Sensor set selection and arrangement
If mounting horizontally, always mount the sensor set so that it is offset at angle of +30° to the
top of the measuring pipe to avoid incorrect measurements caused by empty space at the top of
the pipe.

Proline Prosonic Flow P 500
Endress+Hauser 7
The sensors can be arranged in different ways:
• Mounting arrangement for measurement with 1 sensor set (1 measuring path):
• The sensors are located on opposite sides of the pipe (offset at 180°): measurement with 1 or 3
traverses
• The sensors are located on the same side of the pipe: measurement with 2 or 4 traverses
• Mounting arrangement for measurement with 2 sensor sets (2 measuring paths):
• 1 sensor of each sensor set is located on the opposite side of the pipe (offset at 180°):
measurement with 1 or 3 traverses
• The sensors are located on the same side of the pipe: measurement with 2 or 4 traverses
The sensor sets are arranged on the pipe, offset by 90°.
Using 5 MHz sensors
Here, the rails of the two sensor sets are always arranged at an angle of 180° to one another
and connected by cables for all measurements with 1, 2, 3 or 4 traverses. The sensor functions
are assigned in the two rails via the transmitter electronics unit depending on the selected
number of traverses. It is not necessary to swap the cables in the transmitter between the
channels.

Operating frequency selection
The sensors of the measuring device are available with adapted operating frequencies. These
frequencies are optimized for different properties of measuring pipes (material, pipe wall thickness)
and media (kinematic viscosity) for the resonance behavior of the measuring pipes. If these
properties are known, an optimum selection can be made according to the following tables 1). If these
properties are not (completely) known, the sensors can be assigned as follows:
• 5 MHz for DN 15 to 65 (½ to 2½")
• 2 MHz for DN 50 to 300 (2 to 12")
• 1 MHz for DN 100 to 4000 (4 to 160")
• 0.5 MHz for DN 150 to 4000 (6 to 160")
• 0.3 MHz for DN 1000 to 4000 (40 to 160")

• If clamp-on sensors are used, a 2 traverse-type installation is recommended. This is the
easiest and most convenient type of installation, particularly for measuring devices whose
pipe can only be accessed from one side.
• A 1 traverse installation is recommended for the following installation conditions:
• Certain plastic pipes with a wall thickness >4 mm (0.16 in)
• Pipes made of composite materials (e.g. glass-fiber reinforced plastic)
• Lined pipes
• Applications with media with high acoustic damping

Measuring mode
Two-path measurement with FlowDC 2) (standard configuration)
In the case of two-path measurement with FlowDC, the flow is measured by two measurements at
the measuring point.
For this, the two sensor sets are installed on the measuring pipe, offset at a specific angle to one
another (180° for 1 traverse, 90° for 2 traverses). This is independent of the rotation position of the
two sensor sets on the measuring pipe.
The measured values of both sensor sets are averaged. Based on this average measurement value,
the measured value is compensated depending on the type of disturbance and the distance from the
measuring point to the disturbance point. This makes it possible to maintain the specified accuracy
and repeatability for measurements in non-ideal conditions (e.g. short inlet runs), with inlet runs up
to only 2x DN before and after the measuring point.
The configuration of the two measuring paths is only performed once and is adopted for both
measuring paths.

Single-path measurement (alternative configuration)
In the case of single-path measurement, the flow is measured at the measuring point without the
option of compensation.
For this, it is necessary to comply strictly with the specified inlet and outlet runs after the
disturbance points (e.g. curves, extensions, reductions) in the pipe.
To ensure the best possible measurement performance and measuring accuracy, the standard
configuration with two sensor sets 3) with FlowDC is recommended.

Protecting access via hardware write protection
Write access to the device parameters via the local display, Web browser or operating tool (e.g.
FieldCare, DeviceCare) can be disabled via a write protection switch (DIP switch on the
motherboard). When hardware write protection is enabled, only read access to the parameters is
possible.
Hardware write protection is disabled when the device is delivered.
Protecting access via a password
Different passwords are available to protect write access to the device parameters or access to the
device via the WLAN interface.
• User-specific access code
Protect write access to the device parameters via the local display, Web browser or operating tool
(e.g. FieldCare, DeviceCare). Access authorization is clearly regulated through the use of a user-
specific access code.
• WLAN passphrase
The network key protects a connection between an operating unit (e.g. notebook or tablet) and the
device via the WLAN interface which can be ordered as an option.
• Infrastructure mode
When the device is operated in infrastructure mode, the WLAN passphrase corresponds to the
WLAN passphrase configured on the operator side.
User-specific access code
Write access to the device parameters via the local display, Web browser or operating tool (e.g.
FieldCare, DeviceCare) can be protected by the modifiable, user-specific access code.
WLAN passphrase: Operation as WLAN access point
A connection between an operating unit (e.g. notebook or tablet) and the device via the WLAN
interface, which can be ordered as an optional extra, is protected by the network key. The WLAN
authentication of the network key complies with the IEEE 802.11 standard.
When the device is delivered, the network key is pre-defined depending on the device. It can be
changed via the WLAN settings submenu in the WLAN passphrase parameter.
Infrastructure mode
A connection between the device and WLAN access point is protected by means of an SSID and
passphrase on the system side. Please contact the relevant system administrator for access.
General notes on the use of passwords
• The access code and network key supplied with the device should be changed during
commissioning.
• Follow the general rules for generating a secure password when defining and managing the access
code or network key.
• The user is responsible for the management and careful handling of the access code and network
key.
Access via Web server
The device can be operated and configured via a Web browser with the integrated Web server. The
connection is via the service interface (CDI-RJ45) or the WLAN interface.
The Web server is enabled when the device is delivered. The Web server can be disabled if necessary
(e.g. after commissioning) via the Web server functionality parameter.
The device and status information can be hidden on the login page. This prevents unauthorized
access to the information.
For detailed information on device parameters, see:
The "Description of Device Parameters" document
Access via service interface (CDI-RJ45)
The device can be connected to a network via the service interface (CDI-RJ45). Device-specific
functions guarantee the secure operation of the device in a network.
