Principle of operation
Swimming against the stream requires greater physical strength than swimming with the stream. This
is the simple fact on which ultrasonic ow measurement according to the phase difference process is
based. Two sensors positioned opposite one another send and receive ultrasonic signals in alternation.
When static media are used, both sensors receive the sent ultrasonic signal in phase, meaning without
phase difference. If owing media are used, there is a phase shift. The phase shift is different when
measured in the direction of current than when measured against the direction of current. The phase
difference is directly proportional to the speed of the ow. The ow volume is determined from the
speed of the ow and the known diameter of the pipeline.
Safety notes
• Read the instruction manual before commissioning.
• Connection, mounting, and setting only to be done by trained specialists.
• The Flowcont UN is not a safety module according to the EU Machinery Directive.
• Observe the national safety and work safety regulations.
• Repairs may only be carried out by the manufacturer. Changing or altering the device is not
permitted.
• Wiring work and opening and closing of electrical connections are only to be carried out in a de-
energized state.
• Incorrect handling or improper use can lead to malfunctions in your application.
• Flowcont UN can be used by the Pressure Equipment Directive (PED) of group 2 only for „non-
hazardous liquids.“
Applications
The Flowcont UN ow meter is particularly suited for measuring highly dynamic processes in pipelines.
The device measures liquids. It can be used in the following applications, to name but a few:
• Chemical supply for controlling, logistics and monitoring
• Filling processes in the food industry
• Production machines for controlling and monitoring formulae
• Valve control for dosing liquid volumes
• DI water supply
• Dynamic processes
The following featured comprise its performance characteristics:
• no moving parts, and thus no wear
• high reproducibility
• ease of cleaning
• tamper-proof
• compact design
• integrated empty pipe detection
• chemical resistance
• integrated display with membrane keyboard

Installation notes
An arrow on the measuring channel of the Flowcont UN indicates the ow measurement direction.
The measuring device must be installed such that the ow passes through the measuring tube in the
direction of the arrow.
TOP -> Outlet
Bottom -> Inlet
Optimal FLowcont UN mounting orientation
To detect gases as quickly as possible, the pipeline between the storage container and the FFU
should be as short as possible. An error-free measurement can only be ensured when the pipeline is
completely full and when no liquid is being released as gas. In the case of dosing applications, it may
be useful to position the FFU as close to the dosing valve as possible, because tubing tends to expand
in diameter depending on system pressure. This can lead to deviations.
To avoid cavitations, depending on the measured liquid it can be helpful to have sufcient
backpressure on the outlet Flowcont UN
If any solid particles are present, this can lead to measurement errors.
When pumps are used, the ow sensor must be mounted in the ow direction behind the pump (on
the delivery side) in order to ensure that adequate pressure will be available. The maximum pressure
rating of the FFU must be observed. In order to ensure correct volume ow measurement using the
FFU, in inlet and output paths should be straight and free of obstacles. The minimum inlet and output
paths are dependant on the nominal size:
DN10 DN15 DN20 DN25
Inlet zone 10 cm 30 cm 50 cm 80 cm
Outlet zone 0 cm 5 cm 10 cm 20 cm
Always make sure that the maximum torque of the nuts for the hydraulic connections is not overstep.
Please use the supplied seals. If you seal with teon tape that can result in to excessive tightening
torques. We commend a maximum torque depending on the diameter of:
DN10 DN15 DN20 DN25
Torque G 2 Nm 3 Nm 4 Nm 6 Nm
Caused by the material characteristics of PSU the Flowcont UN has a limited resistance
against UV rays Remind this when mounting Flowmax outdoor

Mounting
The measuring device is mounted in the pipeline using a process connection. In order to ensure
optimal gas venting, we recommend mounting the Flowcont UN vertically in the pipe. The device
should not be mounted behind an output valve, or it might run idle. To prevent outgassing and bubble
formation in the media during the ow measurement, the Flowcont UN should always be mounted on
the pressure side of the system pump.
If the device cannot be mounted vertically, the pipe in which the measuring device is located should
always be full. Preventing the formation of gas bubbles in the Flowcont UN measuring channel will aid
optimal measurements.
For applications with a „Clean Design“ when complete drain of the measuring tube is needed, we
recommend to mount the ow meter in vertical position. When ow meter is mounted horizontal
caused by the internal geometry of the device there might be a rest of liquid inside.
Attention: The process connections from the FFU are offset by 5 mm (see dimensional drawing on
page 17-19).
Mounted Flowcont UN must alway be mechanically stress free. Strong tension in the pipe system can
lead to damage to the devise. Shocks or mechanical loads can affect the measurement accuracy of
the measuring device. If the FFU must be additionally secured due to the presence of vibrations or
mechanical
motion, two mounting clamps can be mounted to the inlet and outlet of the measuring device.

Application with hot uids
In applications where the Flowcont UN is subject to high heat (t < 60 °C), we recommend mounting
the measuring device and electronic housing beneath the measurement area. This allows the heat to
radiate upwards and reduces its effects on the device electronics.

Electrical connection
The Flowcont UN is connected via a ready-made cable socket with M12x1 plug, with 5 pins or 8
pins. Plug in the cable socket without power onto the sensor and screw it tight. Connect the cable in
accordance with its function. After application of the supply voltage, the sensor carries out a self-test
– in an installed state, the sensor is ready for operation after the self-test has been concluded (ca. 4
s) – the display shows the current measured value.
