Level gauges

GESPASA level gauges and remote monitoring systems

Level gauges and remote monitoring systems by GESPASA

GESPASA develops advanced solutions for level control in fuel tanks and other industrial fluids, combining metrological accuracy, smart connectivity and maximum operating reliability.
The DOLPHIN and GENIUS level gauges are part of this product range, designed to meet the requirements of both fixed and mobile installations, as well as distributed environments where remote supervision is essential.
Thanks to integration with digital platforms such as DieselPlus.net and compatibility with automation systems, these gauges make it possible to manage levels in real time, reduce manual intervention and prevent operating risks such as overfills or downtime due to lack of supply.

The DOLPHIN gauge is specially intended for users who need full remote monitoring.
Installed on the tank, it transmits information via the 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, consult consumption history and receive notifications in critical situations, all without the need to travel.

For its part, the GENIUS electronic level indicator is ideal for atmospheric tanks where direct local reading is required.
It measures the level with high accuracy by means of the static pressure of the liquid, and displays the data 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 wider management is required.

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

DOLPHIN gauge – Precise remote monitoring of fluid level in tanks

The DOLPHIN level gauge by GESPASA is an advanced technological solution for remote monitoring of the level of liquids in tanks containing diesel, petrol, AdBlue® or any other compatible fluid.
Designed to provide continuous monitoring via the Internet, this gauge makes it possible to supervise in real time the available volume in the tank from any connected device: smartphone, tablet or computer.

Through integration with the web platform DieselPlus.net and the DieselPlus Tanks mobile app, the DOLPHIN gauge 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 service stations or industries that require permanent visibility of tank levels, without the need to travel physically to them.

Technology and smart operation

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

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

View the current level in real time
Consult consumption history
Configure 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 this without additional cables or complex installation systems.
In addition, it allows alert thresholds or data transmission frequency to be adjusted according to operational needs.

Remote management from DieselPlus.net or the DieselPlus Tanks app

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

Monitor multiple tanks at different locations
Detect possible leaks or abnormal consumption
Anticipate replenishment needs
Coordinate deliveries more accurately

The DieselPlus Tanks mobile app puts this information in your pocket, with a clear, accessible and secure interface.
This allows the technical or logistics manager to react quickly to any event without needing to be physically present at the facilities.

Safety, accuracy and reduced operating costs

In addition to convenience, the DOLPHIN gauge offers a high level of safety and reliability.
By avoiding the need to open tanks repeatedly for visual inspection, it reduces the risk of contamination of the fluid, as well as staff exposure to hazardous conditions.
The accuracy of the measurements also prevents errors in planning replenishment or in stock control.

This system minimises unnecessary journeys, reduces manual monitoring times and improves the traceability of consumption, which translates into direct savings in operating costs and greater efficiency in fuel management.

Recommended industrial applications

The DOLPHIN level gauge is ideal for:

Transport and logistics companies
Agricultural co-operatives with multiple storage points
Civil engineering sites, where diesel control is key
Industrial facilities with internal consumption
Municipal services, machinery depots or waste collection services

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

GENIUS – Electronic level indicator for atmospheric tanks

The GENIUS by GESPASA is a high-accuracy electronic level indicator, designed for continuous reading of the volume of liquid stored in atmospheric tanks, regardless of their shape or arrangement.
Whether the tanks are rectangular, cylindrical, horizontal or vertical, the GENIUS system adapts easily, offering 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, allowing it to obtain a direct level measurement without the need for moving components or floating sensors, thereby minimising maintenance and increasing durability.

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

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

Easy installation and versatile configuration
The GENIUS has been developed to make installation easier on a wide variety of tanks.
Its installation does not require modification of the tank geometry, as the system can be adapted to both site-built tanks and metal or plastic tanks, provided that they are atmospheric (without positive internal pressure).

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

Integration into control systems
Although GENIUS offers 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 possible to use it in more complex installations, where several tanks are managed or an overall view of consumption and fluid inventory is required.

Its application is ideal in industrial, agricultural, logistics or energy sectors, where fuel, oils, chemicals or water are stored, and where constant monitoring of the level is required to avoid overflows, production stoppages 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 offers reliability without direct contact with the fluid, while its digital display enables practical and efficient level management.

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