2. Function
The AirFlow P is a volumetric ow meter specially designed for dusty applications.
The sensor technology is based on the electrodynamic measuring principle. Every particle that
ies past the antenna within a radius of 300 mm generates an electrical signal. The signals
from the two antennas are further processed in the sensor‘s electronics box. The electronics
box of the sensor correlates the received signals of both antennas with each other and thus
determines the velocity.
For an output of the volume ow, the area of the pipe to be monitored must be stored in the
evaluation unit. The evaluation unit then calculates the measured velocity with the specied
area (A x v = m3/time).
The AirFlow P can also be used for pure speed measurement.

3. Safety
The measuring system has a state of the art, reliable design. It was tested and found to be in a perfectly safe
condition when leaving the factory. Nevertheless, the system components may present dangers to personnel
and items if they are not operated correctly.
Therefore, the operating manual must be read in full and the safety instructions followed to the letter.
If the device is not used correctly for its intended purpose the manufacturer's liability and warranty will be void.
3.1 Normal use
•The measuring system may only be installed in metallic pipes to measure the medium passing
through them. It is not suitable for any other use or measuring system modications.
•Only genuine spare parts and accessories from ENVEA Process may be used.
3.2 Identicationofhazards
•Possible dangers when using the measuring system are highlighted in the operating instructions with
the following symbols:
Warning!
•This symbolises a situation where personal safety is at risk if used in an improper manner.
Attention!
•This symbolises the possible damage to the system, if used in an improper manner.
3.3 Occupational and operational safety
•The measuring system must be installed by trained and authorised personnel only.
•Protective equipment must be worn to avoid injuries caused by possible sharp edges on the
measuring device.
•When using a cable with more than 4 cores, unused, open cores may cause sparking. Failure to
comply with the specied connection parameters of the cable will result in loss of intrinsic safety. To
prevent this, it is mandatory to use a 4-core shielded cable.
Always ensure that the connection parameters of the cable are within the specication (Li, Ci). The
shield of the cable must not be connected to the housing under any circumstances.
•When installed in an Ex zone, there is an increased risk of explosion, so it should always be ensured
that there is no Ex zone when carrying out installation work.
•Improper installation work leads to an increased risk of explosion. The device must always be installed
using the process-related seals and observing the torques. Mechanical stresses are to be avoided, for
example through supported installation.
•In case of improper assembly, there is an increased risk of explosion due to escaping dusts.
•When installing the measuring device, there is a risk of injury due to crushing. To avoid this, installation
work must always be carried out by two people.
•Improper mechanical stress (e.g. torsion) can cause damage to the device. To avoid this, the device
should always be installed in accordance with all the instructions in the operating manual.
The measuring device should also not be exposed to any vibrations if possible.

•If the device is operated under high pressured conditions, there is a risk of explosion. When cleaning
or blowing out the pipe and when transporting material, always ensure that the permissible pressure
according to the DGRL is not exceeded.
•Due to the process, hot components on the device can cause burns. It is strongly recommended to
wear the appropriate protective equipment and to let the device cool down before working on it.
•Improper use of the device will result in a high risk to system safety, therefore the device must only be
used as specied in the associated documentation.
•Make sure that the system is in a depressurised state during all maintenance, cleaning and inspection
work on the pipelines or on the components of the device.
•Switch off the power supply for all maintenance, cleaning or inspection works on the sensor or on
components. Follow the notes of the chapter maintenance.
•Caution, if welding is required on the pipe, remove sensor.
•The components and electrical connections must be checked for damages regularly. If a damage is
found, it is to be repaired before further operation of the instruments.
Risk of explosion, electric shock or damage due to incorrect or non-existent earthing
Incorrectly connected equipotential bonding can result in charges that can lead to explosions in an
explosive atmosphere, electric shock or device damage.
• Connect equipotential bonding at all points provided on the device components.
• For all work on the device described in these operating instructions, ensure that the equipotential
bonding is connected.
• Ensure that there is an earth connection via the power supply.
• Carry out regular checks of the earthing connections for correctness.
Risk of explosion from electrostatic charge when cleaning or blowing out
• No dangerous electrostatic charges may occur during cleaning and blowing out.
Standardization
• The provisions of IEC / EN 60079-17 must be observed during commissioning, installation and
maintenance.
Risk of explosion or electric shock due to improper installation work
Improper assessment of the installation site and all other installation work in the hazardous area can cause
serious damage to people and the company.
• Installation, commissioning, maintenance and testing may only be carried out by qualied personnel
who have knowledge of the rules and regulations for potentially explosive areas, in particular:
• types of protection
• installation rules
• zoning
• applicable standards
• local work safety regulations

10
3.4 Maintenance
•For maintenance purposes, it is imperative that the device is de-energised and cooled down,
otherwise there is an increased risk of explosion.
•Before working on the device or its components, it is essential to ensure that they are de-energised.
Otherwise there is a risk of electric shock.
•The correct tool must be used to open the device, otherwise there is a risk of injury and crushing.
•Before opening the device or its components, it is imperative to ensure that there is no EX zone.
•During cleaning work on the device or in the process, there is an increased risk of explosion due to
electrostatic discharges and excessive pressures.

3.7 Storage conditions
Observe the following instructions during storage:
•To ensure shock resistance, store in original packaging.
•Do not remove protective discs or caps mounted on process connections.
They prevent mechanical damage and contamination to the sealing surfaces.
•Protect from sunlight to avoid impermissibly high surface temperatures.
•Store in a dry and dust-free place.
•Do not store outside.
Risk of electric shock when opening the evaluation unit
• Only open the housing if the system has previously been disconnected from the power supply.
Damage to the device due to improper mechanical stress
Improper handling (all mechanical stresses, e.g. torsion) can no longer guarantee pressure tightness.
• Tighten screw connections only with the torques specied in the operational instructions.
Risk of crushing with risk of injury when opening the lid
• Make sure to wear suitable protective equipment (e.g. gloves).
Risk of injury from sharp edges or splinters
• Make sure to wear suitable protective equipment (e.g. helmet, glasses, gloves, work shoes).

4. Mounting and installation
4.1 Supplied equipment
•Evaluation unit in the DIN Rail housing or eld housing
•Double weld-on socket for sensor mounting
•Sensor (consisting of 2 x antenna, 1 x electronic box)
•Assembly instructions
•C1- or C3-Box (optional)
4.2 Required tools
•Open-end wrench (36 mm)
•PZ 2 cross-recess screwdriver
•Suitable tools for the electrical connection
4.3 Determining the installation position
To determine the correct position of the AirFlow P, proceed as follows:
•The sensor can be used in round or angular pipes. In the case of horizontal or sloping
pipelines, the installation should be carried out from above.
•Depending on the geometry and size of the line to be monitored, several sensors are used:
- From a line size of 1500 mm 2 sensors are used.
- From a line size of 3000 mm 3 sensors are used.
•If several sensors are required for one measuring point, all sensors are distributed evenly on
the line at one installation height.
Optimally, the duct or pipeline continues horizontally or vertically upstream and downstream of
the installation point, and xtures such as bends, aps or gate valves have a minimum distance
to the sensor in both directions. (See Fig. 6)

In applications where the mounting location requirements cannot be fully met, the best
possible mounting position should be selected.
1. The AirFlow P should be installed so that the two antennas of the sensor are aligned with
the material ow.
2. In horizontal pipes with a round cross-section, the AirFlow P can be installed in any position
above the horizontal axis (between 9 and 3 o‘clock).
3. In horizontally running lines with a square cross-section, the installation can take place
centrally at the top or at the side.
4. Even if the sensor is not impaired in its function by vibration, strong vibrations should be
avoided as they can lead to the destruction of the electronics.
5. The sensor should not be exposed to direct sunlight, nor should it be used in areas with an
ambient temperature of more than 60 °C.
6. The sensor rods must not have any contact with the opposite line wall or any other device!
This would short-circuit the electrodynamic signal. To prevent this condition, the length of
the antennas can be shortened to a minimum length of 120 mm. The length of the antennas
is measured from the end of the screw-in thread.
The ceramic sleeve must not be damaged in any way.
7. In any case, it must be ensured that no contact occurs due to bridging in the event of
coating formation on the inner wall of the pipe.
8. For application with a smaller diameter than DN200, it is needed to ll in the questionaire,
so ENVEA Process will shorten the antennas to the correct length.
4.4 Installation in non-metallic lines
The sensor must be installed in a metallic duct to achieve sufcient shielding against electrical
inuences. In the case of non-metallic ducts, a sheathing of metal, a metal foil or a ne-meshed
metal mesh with a length of approx. 5 times the pipe diameter must be made upstream and
downstream of the measuring point. Furthermore, make sure that the duct and the sensor are
well grounded.

13
4.5 Installation of the sensor
At the selected installation position, the double weld-on sleeve must be installed on the line
wall and drilled out completely to the inner diameter of the sleeve. The sleeve must be installed
with the material ow direction.
Attention!
•After drilling, it is essential to check whether any burr has formed on the drill edges as a result
of drilling. Any burr that may have arisen in the pipe must be removed with an appropriate
tool. If the burr is not removed, this can have an influence on the calibration of the sensor!
•The two antennas are then screwed in tightly. The connections are to be checked for
tightness, appropriate sealing tape is to be used.
•Once both antennas are installed, the electronics box is pushed onto the antennas and
secured using the TriClamp connection. If the installation is correct, it should be possible to
insert the connectors of the electronics box into the antennas with a perfect fit.
•If the sensor is not installed immediately, the sealing caps must be screwed in until the time
of installation.
Attention!
•Use the correct tool (spanner size = S36) and apply it to the G 1“ screw connection.
•Use sealing tape
•Improper installation will void the warranty!
•Observe the seal on the TriClamp connections!
