Today, the tank bottle is already part of the new standard for many leisure and camping vehicles. With the new WAVE wireless module, you can now view the exact fill level of your tank on your mobile phone, get automated information about fill levels, have fill level warnings sent and maintain control of your gas consumption at all times.

Loosen or tighten the screws of the indication component with the Allen tool included in the scope of delivery.

Remove the existing indication component and insert the new one in its place.

Remove the cover from the indication component and insert the plug of the wireless module completely (click).

Attach the bracket to the wall with the adhesive tape, plug in the wireless module, download the app and you’re done!

For details on how the system works or how to use the app, refer to the user manual.

Frequently asked questions


Why do I have to register and be logged in for the app to display data at all?

The data is not stored locally on your phone, but centrally on a cloud server. This allows you to change your device without losing your data. To be able to allocate your data, we need user accounts.


What is the GPS data needed for?

The “DIMES” product range also includes a solution for stationary containers (heating) – to be able to offer corresponding services (e.g. automatic filling), the data must be evaluated (customer, location, fill level). Furthermore we plan to include all available LPG filling stations in a later version of the app. This will enable you to find the nearest petrol station directly in the app.


Why does my tracking service have to be activated?

The providers Apple and Android do not allow Bluetooth connection if tracking services are disabled.


What data is collected and what happens to it?

The data will be sent exclusively to us (ROTAREX S.A.). You can find further information at


I am asked for a PIN when configuring the app. Where is it located?

The PIN is located on the sticker on the back of the module.


Can I measure the level with the DIMES without an internet connection?

The current fill level can also be read without an Internet connection. Only the charts/graphs are set up via the cloud server.


The app is showing me a wrong fill level

If the app is showing REFILL (empty) although you knowingly have a full gas bottle (or generally get a wrong display), this may be due to the special feature of the “first alignment” of the sensor. As this is a mechanical level sensor which transmits the fill level from the valve to the display unit via a magnetic connection, under special circumstances it is possible that the two magnets “jam” together. Only when the float is moved the magnets are correctly aligned (by gas extraction and/or by vibrations during travel). Alternatively, the magnet in the sensor can be influenced with an external magnet so that it is manually released. For this reason the app should be set up and tested during installation before the sensor is screwed together (in this case the sensor can be adjusted again manually using an external magnet. Unfortunately, this problem is due to the design and cannot be solved constructively. The problem only exists once – once the system is aligned, this problem will not reoccur. This could have produced an incorrect value during your first measurements (which is why the level seems to have increased).


The plug can no longer be removed from the sensor

The plug connection is designed according to protection class IP54, which requires a good and secure connection. To release the connection, it is best to use a small (slotted) screwdriver, with which you press in the latch directly above the plug connection to be able to pull the plug upwards.


Can several devices be connected simultaneously?

The DIMES transmitter unit can only establish one connection at a time, but they can connect several devices (just not in parallel). This situation is due to the Bluetooth Low Energy (BLE) standard.


How often is the data updated?

The default frequency is 12 hours, under ANDROID (Apple unfortunately does not support this functionality) you can set the cycle yourself (Menu – Global Settings – Advanced Settings). Please enter the value in minutes (e.g. 120 for an automatic update every 2 hours). Please also consider that a shorter transmission frequency also means higher energy consumption (battery life).
