GESPASA level probes and remote monitoring systems

Level probes and remote monitoring systems GESPASA

GESPASA develops advanced solutions for level monitoring in fuel tanks and other industrial fluids, combining metrological accuracy, smart connectivity and maximum operational reliability.
The DOLPHIN and GENIUS level probes are part of this range of equipment designed to meet the requirements of both fixed and mobile installations, and for distributed environments where remote supervision is essential.
Thanks to integration with digital platforms such as DieselPlus.net and compatibility with automation systems, these probes enable real-time level management, reduce manual interventions and help prevent operational risks such as overflows or downtime due to lack of supply.

The DOLPHIN probe is specifically designed for users who need complete remote monitoring.
Installed on the tank, it transmits information via Internet, providing instant access to the fluid level from smartphones, tablets or PCs.
From the DieselPlus platform or the DieselPlus Tanks mobile app, users can configure automatic alarms, view consumption history and receive notifications of critical situations, all without having to travel to site.

Meanwhile, the GENIUS electronic level indicator is ideal for atmospheric tanks where a direct local reading is required.
It measures the level with high accuracy using the static pressure of the liquid and displays the value on an integrated digital display.
Its versatility allows installation on tanks of different shapes and heights, and it can be connected to external control or automation systems if integration into broader management is required.

Both solutions enhance operational efficiency, safety and logistics control of fluid consumption, and are designed for easy integration into modern industrial processes.
Whether through remote monitoring or direct visualisation, GESPASA ensures reliable measurement, easy installation and real reduction in operating costs.

DOLPHIN Probe – Precise remote monitoring of fluid level in tanks

The GESPASA DOLPHIN level probe is an advanced technological solution for remote monitoring of liquid levels in diesel, petrol, AdBlue® tanks or any other compatible fluid.
Designed to provide continuous monitoring via the Internet, this probe enables real-time supervision of the available volume in the tank from any connected device: smartphone, tablet or computer.

Through integration with the DieselPlus.net web platform and the DieselPlus Tanks mobile app, the DOLPHIN probe transforms the way fuel storage is managed, moving from manual inspection to automated digital monitoring.
This technology is ideal for fleets, agricultural operations, co-operatives, private fuelling stations or industries that require permanent visibility of tank levels without needing to travel to the site.

Technology and smart operation

The DOLPHIN is installed directly on the tank and transmits continuous fluid level readings via a wireless connection.
Thanks to its compact, robust design and easy installation, it adapts to different types of tanks without the need for complex structural modifications.

Once installed, it automatically connects to the DieselPlus cloud, from where the user can:

View the current level in real time
Check consumption history
Set automatic alarms for low level, filling or overfill
Receive instant notifications by email or in the app
Download consumption reports for auditing or internal control

All without additional cables or complex installation systems.
It also allows alert thresholds and data transmission frequency to be adjusted according to operational needs.

Remote management via DieselPlus.net or the DieselPlus Tanks app

One of the key differentiators of the DOLPHIN probe is its full integration with the DieselPlus ecosystem, the online platform developed by GESPASA for smart management of fuel consumption.
From a single dashboard, it is possible to:

Monitor multiple tanks across different locations
Detect potential leaks or abnormal consumption
Forecast refilling needs
Coordinate deliveries more accurately

The DieselPlus Tanks mobile app keeps this information at your fingertips, with a clear, accessible and secure interface.
This enables the technical or logistics manager to respond quickly to any event without needing to be on site.

Safety, accuracy and lower operating costs

In addition to convenience, the DOLPHIN probe offers a high level of safety and reliability.
By avoiding frequent opening of tanks for visual inspection, it reduces the risk of contamination of the fluid, as well as personnel exposure to hazardous conditions.
The accuracy of the measurements also helps prevent errors in planning refuelling or in stock control.

This system minimises unnecessary travel, reduces manual supervision time and improves traceability of consumption, translating into direct savings in operating costs and greater efficiency in fuel management.

Recommended industrial applications

The DOLPHIN level probe is ideal for:

Transport and logistics companies
Agricultural co-operatives with multiple storage points
Civil engineering, where diesel monitoring is critical
Industrial facilities with internal consumption
Municipal services, plant fleets or waste collection

Thanks to its full connectivity and integration into a professional platform, it is a key tool for optimising fuel use, planning procurement and ensuring there are never interruptions due to lack of supply.

GENIUS – Electronic level indicator for atmospheric tanks

The GESPASA GENIUS is a high-accuracy electronic level indicator, designed for continuous reading of the liquid volume stored in atmospheric tanks, regardless of their shape or layout.
Whether rectangular, cylindrical, horizontal or vertical, the GENIUS system adapts easily, providing reliable measurements up to a maximum height of 4 metres.

Unlike other measurement systems that require complex structures or invasive sensors, GENIUS operates by reading the static pressure exerted by the column of liquid, enabling a direct level measurement without moving components or float sensors. This minimises maintenance and increases durability.

Accurate, adaptable measurement
The operating principle of GENIUS is based on a calibrated pressure cell that captures the height of the liquid based on the pressure exerted at a reference point.
This method, widely used in industrial applications, offers high reading stability, even when there are minor thermal fluctuations or variations in product viscosity.

The system includes an electronic unit with an integrated digital display, enabling the current level of the tank to be checked locally, without relying on external platforms.
This direct visualisation makes GENIUS extremely useful for operators and technicians who need to check levels frequently or make immediate decisions regarding inventory management.

Easy installation and versatile configuration
GENIUS has been developed to facilitate installation on a wide variety of tanks.
Its installation does not require changing the geometry of the tank, as the probe adapts to both construction tanks and metal or plastic tanks, provided they meet the atmospheric condition (no positive internal pressure).

In addition, the system is configurable to match the height and shape of the tank, allowing the reading to be scaled to the container’s actual volume.
Thanks to its robust, compact design, it is suitable for demanding industrial environments where accuracy and resistance to external factors are essential.

Integration into control systems
While GENIUS provides autonomous, local reading, it can also be integrated into automation or centralised control systems by connecting the output signal to a PLC or remote controller.
This makes it suitable for more complex installations where multiple tanks are managed or where an overall view of consumption and fluid inventory is required.

It is ideal for industrial, agricultural, logistics or energy sectors where fuels, oils, chemicals or water are stored, and where continuous level monitoring is required to prevent overflows, production downtime or critical supply situations.

The GENIUS electronic level indicator is the optimal solution for those seeking a precise, durable and versatile tool for monitoring atmospheric tanks.
Its static-pressure-based technology delivers reliability without direct contact with the fluid, while its digital display enables practical, efficient level management.

Available for tanks up to 4 metres in height, GENIUS combines ease of use with the ability to integrate into professional systems, positioning itself as a key component in automation and efficiency of liquid management in any technical environment.
