Automated management of stock and alarms of fuel products

Always more often depots and service stations have the need to centralize data relating to stocks and alarms.

Coptron has developed a series of equipment that are part of a flexible, scalable system able to give the correct answer to each specific request.
The tank monitoring system is set up taking in mind the features of each system. We create a customized solution using standard products (tested and supported).

The monitoring is on three different levels of management:
central headquarter, storage/service area, storage tanks.


Example of activities and necessary devices

We can follow you in every necessary step to implementing a monitoring solution. We are able to provide you all the necessary equipment and support you in the installation and configuration of these, as well we can provide you the finished and complete system. The steps are the following:

  • Supply and installation of level sensors and density meters on underground and aboveground tanks containing petroleum products (gasoline, diesel fuels, agriculture and heating).
  • Reading data from the probes and sensors on the area.
  • Supply, installation, testing and start up of all the necessary equipment.
  • Training in the use of software for managing remote data from the level sensors at the head office and stores/service stations.
  • Transmission of data from the site where will be placed the probes to a central server for access via the web through the use of ADSL line or other suitable technical solutions to data transfer.
  • Testing and declaration of installation - Declaration of conformity in accordance with italian law DM 37/08.

Details of the different levels of management

With the Coptron MasterTankTre management software can monitor in real time (via LAN connection, WAN or Internet) levels and alarms of units installed on the systems and access historical data collected. When an Alarm Remote allows sending emails to a contact list.

Our system allows you to monitor:

  • Level and product volume
  • Product volume compensated to 15°C
  • Presence of water (level and volume)
  • Temperature
  • Ullage
  • Customized alarms (low/high level, losses, ecc.)
  • Product density

The MasterWebTre module that integrates MasterTankTre, allows to make available on the web the tracking information. The application is cross-platform (PC, tablet and smartphone) and accessible from any device connected to the network; the system allows, after user authentication, to view the list of facilities and levels of detected alarms. MasterWebTre is multi-user and allows you to set specific viewing rights to every user.

In the storage area (either a store or a gas station) there is the control unit for the acquisition of data from the storage tanks; the latter can be connected by cable or wireless, depending on the construction and logistic specificity of the plant itself.

The control unit can operate in "stand-alone" mode or can be connected to a computer through the software MasterTankTre; the same way you can connect the system to a location via a network connection (LAN, WAN or Internet) for centralized data management.


The control unit can be connected via LAN network connection remote devices located on the plant: inventory viewer, alarm, printer.

On the station can be present magnetostrictive level probes for measuring the amount of product in the tanks, the temperature and the possible presence of water detection, densimeters, interspace sensors, losses sensors and manhole anti-theft sensors. The communication between these devices and the data collection unit can take place in different ways, depending on the operational and logistical conditions present in the system.

The wired solution is surely the most recommended: it's the most reliable and less costly in time in terms of maintenance. The direct cable connection of the probes and of the various sensors to the control unit ensures a stable communication, avoiding a whole series of problems typical of the connection via radio (interferences, and shielded signal in certain conditions, such as the presence of certain vehicles into the area). On those installations where there are already pipelines useful to the passage of the cables is therefore the solution to be preferred over the other.

The hybrid solution is indicated in those plants where the control unit is placed at a certain distance from the tanks and install the cables until this is particularly burdensome. Probes and sensors are connected via cable to a field concentrator (wireleless gateway), which collect the information and communicates wirelessly with the control unit. Using this type of connection is usually possible to place the wireless gateway in an optimal place, avoiding interference and ensuring a certain stability of communication with the control unit.

The wireless solution uses radio local transmitters (battery powered) to connect each sensor level to a wireless concentrator gateway, which in turn communicates with the control unit. It is essential that the transmitters are optimally positioned to ensure the data is sent to the control unit located in the operator room. This configuration avoids the necessary works to the laying of cables in the square; of against a periodic maintenance is required for the replacement of the batteries.
