3 Product description

Functional principle

The measurement is carried out through a suitable nozzle opening on the vessel.
The instrument emits a continuous, frequency-modulated radar signal through its antenna. The emitted signal is reflected by the medium and received by the antenna as an echo with modified frequency. The frequency change is proportional to the distance and is converted into the level. The measured value is transmitted wirelessly as part of the data transmission.
The measuring cycle described above is time-controlled via the integrated clock. Outside of the measuring cycle, the device is in a sleep mode.

Measured value transmis- Depending on the availability of the radio networks, the device trans-

sion

mits its measured values wirelessly to an LTE-M (LTE-CAT-M1) or NB-

IoT (LTE-CAT-NB1) mobile radio or a plant-side LoRaWAN network.

Installation position

4 Mounting
When mounting the device, keep a distance of at least 200 mm (7.874 in) from the vessel wall. If the device is installed in the center of dished or round vessel tops, multiple echoes can arise. However, these can be suppressed by an appropriate adjustment (see chapter ” Setup”).
If you cannot maintain this distance, you should carry out a false signal suppression during setup. This applies particularly if buildup on the vessel wall is expected. In such cases, we recommend repeating the false signal suppression at a later date with existing buildup.

200 mm (7.87″)
Fig. 6: Mounting of the radar sensor on round vessel tops
In vessels with conical bottom it can be advantageous to mount the device in the centre of the vessel, as measurement is then possible down to the bottom.

4 Mounting Nozzle

For nozzle mounting, the nozzle should be as short as possible and its end rounded. This reduces false reflections from the nozzle.
The antenna edge should protrude at least 5 mm (0.2 in) out of the nozzle.

Fig. 9: Recommended socket mounting of VEGAPULS Air 42
If the reflective properties of the medium are good, you can mount VEGAPULS Air 42 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded.
Note: When mounting on longer nozzles, we recommend carrying out a false signal suppression (see chapter ” Parameter adjustment”).
You will find recommended values for socket heights in the following illustration or the table. The values come from typical applications. Deviating from the proposed dimensions, also longer sockets are possible, however the local conditions must be taken into account.

5 Access protection

5 Access protection

5.1 Bluetooth radio interface
Devices with a Bluetooth radio interface are protected against unwanted access from outside. This means that only authorized persons can receive measured and status values and change device settings via this interface.

Bluetooth access code

A Bluetooth access code is required to establish Bluetooth communication via the adjustment tool (smartphone/tablet/notebook). This code must be entered once when Bluetooth communication is established for the first time in the adjustment tool. It is then stored in the adjustment tool and does not have to be entered again.
The Bluetooth access code is individual for each device. It is printed on the device housing and is also supplied with the device in the information sheet ” PINs and Codes”. It can be changed by the user after the first connection has been established. If the Bluetooth access code has not been entered correctly, a new entry can only be made after a waiting period has elapsed. The waiting time increases with each additional incorrect entry.

Emergency Bluetooth unlock code

The emergency Bluetooth access code enables Bluetooth communication to be established in the event that the Bluetooth access code is no longer known. It can’t be changed. The emergency Bluetooth access code can be found in information sheet ” Access protection”. If this document is lost, the emergency Bluetooth access code can be retrieved from your personal contact person after legitimation. The storage and transmission of Bluetooth access codes is always encrypted (SHA 256 algorithm).

5.2 Protection of the parameterization
The settings (parameters) of the device can be protected against unwanted changes. The parameter protection is deactivated on delivery, all settings can be made.

Device code

To protect the parameterization, the device can be locked by the user with the aid of a freely selectable device code. The settings (parameters) can then only be read out, but not changed. The device code is also stored in the adjustment tool. However, unlike the Bluetooth access code, it must be re- entered for each unlock. When using the adjustment app or DTM, the stored device code is then suggested to the user for unlocking.

Emergency device code

The emergency device code allows unlocking the device in case the device code is no longer known. It can’t be changed. The emergency device code can also be found on the supplied information sheet ” Access protection”. If this document is lost, the emergency device code can be retrieved from your personal contact person after legitimation. The storage and transmission of the device codes is always encrypted (SHA 256 algorithm).

VEGAPULS Air 42 · Autarkic device with measured value transmission via radio technology

64579-EN-210526

7 Operating modes, activate, device functions

Measured value transmis- After activation, a single measurement is carried out and the cyclic

sion

measurement interval is started. The measured value is sent once

via LoRaWAN or mobile radio. The sensor delivers the distance value

from the sealing surface of the thread or flange lower side to the

product surface. The conversion into level is carried out, for example,

in the VEGA Inventory System on the application server or in a cloud

service.

Cyclic measuring operation

In the activated state, the device is woken up via the integrated clock and carries out a measurement cycle (measurement and transmission). The measurement and transmission interval runs on the basis of the factory preconfiguration or a configuration set by the user. Afterwards, the device automatically enters the energy-saving sleep state.
Note: In sleep mode, it is not possible to connect to the device via Bluetooth.

Function Triggering

7.4 Single measurement
The device offers the possibility to test the communication in the respective network. The current measured value is determined and transmitted once outside the cyclic transmission. In addition, a LoRa Join and a single location determination is carried out.
The procedure is done by new activation via NFC or magnet as described above. The sensor is simultaneously activated for the cyclical transmission of measured values. The transmission cycle of an already activated sensor is not changed by this.
7.5 Localization
The LTE-M/NB-IoT version of the device has the function ” Location determination “. This is carried out via an integrated GNSS/GPS receiver via navigation satellites. The function ” Location determination” can be switched on or off via the VEGA Tools app or PACTware/ DTM. 1)
Tilting or raising the device triggers a single location determination. A position of 20° to the vertical must be passed through. Furthermore, entering a new mobile radio cell triggers a single location determination. In both cases, location determination is not started until the next cyclic measured value determination. If no satellite signal is found within 180 s and therefore no position is determined, the process is aborted.
Note: In LoRa mode or with the LoRa version of the device, there is generally no location determination.

8 Transfer measured values and data to the cloud
8.1 Communication basics
To transmit the measured values and data to the cloud, the device requires access to mobile network or a LoRaWAN network at the installation site, depending on the version. If no corresponding network is available, a LoRaWAN gateway must be installed.
Note: Ensure free access to the radio network. The device must not be covered by metal or even enclosed. This especially for the medium height of the housing.
Note: Simultaneous operation of LTE-M or LTE-IoT and LoRaWAN is not supported.
The following measured values or data are transmitted:
· Distance from the medium surface (m) · Electronic temperature (°C) · Geographical position determined by GNSS (geographical coor-
dinates)
· Mounting position (angle °) · Remaining life of Lithium cells (%) · Device status
The transmission options are described below.
8.2 NB-IoT/LTE-M – VEGA Inventory System
With NB-IoT (Narrow band Internet of Things) and LTE-M (Long Term Evolution for Machines), the focus is on low data rates and high transmission ranges. Another focus is on penetrating propagation obstacles, such as buildings, for which the long-wave signal is well suited.

8 Transfer measured values and data to the cloud
After data transmission via the mobile network, the sensors are automatically made known in the VEGA Inventory System via their serial number. As soon as the sensors are integrated there, the data are available for visualisation.
8.3 LoRa-WAN (Fall back) – VEGA Inventory System
LoRaWAN (Long Range Wide Area Network) is the data transmission mode that is available when the mobile network fails. However, this requires a corresponding gateway. This gateway picks up the data via LoRa from the sensors and transmits them via mobile radio to VEGA’s own LoRa server.

Maintenance Precaution measures against buildup
Cleaning

13.1 Maintenance
If the device is used properly, no special maintenance is required in normal operation.
In some applications, buildup on the antenna system can influence the measuring result. Depending on the sensor and application, take measures to avoid heavy soiling of the antenna system. If necessary, clean the antenna system in certain intervals.
The cleaning helps that the type label and markings on the instrument are visible. Take note of the following:
· Use only cleaning agents which do not corrode the housings, type
label and seals
· Use only cleaning methods corresponding to the housing protec-
tion rating

Reaction when malfunction occurs

13.2 Rectify faults
The operator of the system is responsible for taking suitable measures to rectify faults.

Causes of malfunction

The device offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.:
· Sensor · Process · Charge state of the lithium cell · Availability/quality of radio transmission · Signal processing

Fault rectification

The first measures are:
· Evaluation of fault messages · Checking the output signal · Checking the radio quality or availability of the radio standard · Treatment of measurement errors
A smartphone/tablet with the adjustment app or a PC/notebook with the software PACTware and the suitable DTM offer you further comprehensive diagnostic possibilities. In many cases, the causes can be determined in this way and the faults eliminated.

Reaction after fault recti- Depending on the reason for the fault and the measures taken, the

fication

steps described in chapter ” Setup” must be carried out again or must

be checked for plausibility and completeness.

24 hour service hotline

Should these measures not be successful, please call in urgent cases the VEGA service hotline under the phone no. +49 1805 858550.
The hotline is also available outside normal working hours, seven days a week around the clock.

1 Failure – red 2 Out of specification – yellow 3 Function check – orange 4 Maintenance required – blue

Failure: Due to a malfunction in the instrument, a fault message is output.
This status message is always active. It cannot be deactivated by the user.
Function check: The instrument is being worked on, the measured value is temporarily invalid (for example during simulation).
This status message is inactive by default.
Out of specification: The measured value is unreliable because an instrument specification was exceeded (e.g. electronics temperature).
This status message is inactive by default.
Maintenance required: Due to external influences, the instrument function is limited. The measurement is affected, but the measured value is still valid. Plan in maintenance for the instrument because a failure is expected in the near future (e.g. due to buildup).
This status message is inactive by default.

You can find more information about the respective mobile phone provider.

16.3 Radio networks LoRaWAN – Data transmission

LoRaWAN
LoRaWAN (Long Range Wide Area Network) is a network protocol for wireless signal transmission to a corresponding gateway. LoRaWan enables a range of several kilometres outdoors and good building penetration with low power consumption of the transmission module.
In the following, the necessary device-specific details are shown.You can find further information of LoRaWAN on www.lora-alliance.org.

Data stream, byte order, packet structure
The data are transferred as a byte stream in packets. Each packet is given an identifier at the beginning which defines the meaning of the following bytes.
The byte order corresponds to the Cayenne Low Power Payload (LPP) Guideline as BigEndian.
Packet 2 is transferred as standard. Alternative packets are required if additional characteristic values (error status, position) occur in the sensor. The maximum packet size is 52 bytes in Europe and 11 bytes in the USA with maximum spread factor.
A LoRa standard function additionally transmits a packet counter and the serial number of the LoRa module with every packet.
