WEB-SAT fuel technology

Recent years have shown us that an increase in the prices of various products and services is inevitable. This also applies to fuel prices.

2022 has been the record year for diesel and gas prices per liter. Based on the June data, the average price per liter is as high as PLN 8.28 for Pb98, PLN 7.80 for Pb95 and PLN 8.11 for diesel. So how to prepare your company for the rising prices and minimize fuel consumption? That's where WEB-SAT comes to the rescue. Thanks to the state-of-the-art systems adjusted to various types of vehicles we can measure fuel consumption, determine its level and present this data by means of advanced modules and reports. As a result, our clients are able to reduce fuel expenses, point their drivers towards more economical and efficient driving and manage their fleets more effectively.

How does it work?

Every company, regardless of its size and the industry it operates in, has its own specific needs. There are many factors that affect the choice of the correct solution, such as: the size of the fleet, the type of vehicles, their purpose and technical conditions. We adjust our systems and technologies to the client's expectations and needs, depending on the purposes for which the fuel level and consumption data will be used.

Readings are taken using three methods:


This solution is based on reading the fuel level in the vehicle's tank with the use of a factory-installed float. The WEB-SAT GPS device is connected directly to the float. The results are available at the WEB-SAT platform and in the mobile app, which calculate the data on fuel consumption. While this is the cheapest and simplest method, it is subject to a measurement error of 10 to 15%, depending on wear and tear on a car (in older vehicles floats might get stuck and the quality of contact connections and wires deteriorates). The accuracy of measurement is heavily dependent on the electronics of the float itself, its mechanics, as well as the shape of the tank. Despite calibration, floats often have dead-zones caused by the shape of the tank; for example the upper and lower part of the tank do not allow for accurate measurement when the tank is either full or almost empty. That is why the reading is filtered and averaged. In order to improve the precision of fuel measurement, we use advanced algorithms that enhance our devices and mechanisms that support our GPS systems. These solutions ensure the best quality of measurement on the market.

CAN bus

Another way to control the amount of fuel and its consumption is the CAN bus. Every modern vehicle is equipped with a CAN bus, which allows to read large volumes of logistic data, such as: engine speed, gas pedal pressure, mileage, engine temperature and much more. Based on this data, we can analyze the driving style of a driver, which impacts fuel consumption as well as the wear and tear of other operating parts of the vehicle. Once a GPS device has been connected to a CAN module, we gain access to additional data on fuel consumption (average consumption, instantaneous consumption, total consumption – depending on the type and/or model of the vehicle). This is done with the use of the modern platform WEB-SAT and the mobile app, where the data is presented in a clear and concise way through various reports and tools for controlling driving parameters. You can access the CAN data read-out anytime at any place. The fuel data is filtered by a smoothing algorithm to ensure the most accurate reading. As a result, we can eliminate false fueling and fuel loss events, which can be caused by temporary fluctuations in the fuel level in the tank.

Fuel Probe

Probes are the most popular and accurate way of fuel control. Their biggest advantage is the accuracy of measurement of up to 1%. This means that the device can detect the slightest deviation in the liquid level in the tank, so that you can prevent employee dishonesty and possible theft. Fuel probes are recommended particularly for trucks, tractors and construction machinery as those vehicle types are equipped with large fuel tanks that require an accurate measuring tool. Additionally, the probes offered by WEB-SAT are based on a technology that uses the measurement of fuel pressure in the tank. As a result, any changes in the fluid volume level and temperature do not affect the quality of measurement. Another advantage is the high quality of materials used in the probes. We offer the best analog-digital fuel probes that are resistant to the acidic properties of oil, which prevents damage and measurement errors.

Fuel filler security

For additional protection against fuel loss we offer fuel filler security: the plug module BAK-Q60 and BAK-Q80. The module controls and monitors fuel filler access on trucks, machinery, construction equipment and many more. It can optionally be equipped with event signaling devices for the driver and the anti-burglary strainer. The devices have been granted approval No. E20 10R-032916 by the Ministry of Transportation.

Refueling with fuel cards

You can import the data on fuel transactions to our applications. This allows you to compare the amount of fuel purchased as indicated on the document with the amount that was actually refueled. We use two parallel measurements of fuel consumption:

  • Based on the float. This measurement is used to identify refueling/emptying and compare the amount of fuel refueled with the amount of fuel purchased. Note, however, that the accuracy of this measurement depends on the accuracy of the float.
  • Based on the data from the CAN bus for determining the average combustion of the vehicle. This measurement method allows for accuracy to tenths of a liter per 100 km and depends on the make and model of the vehicle.
