Such sensors have become widespread both on stationary objects and on mobile ones. The first category includes stationary storage devices (for example, gas stations). The second category includes vehicles ranging from passenger cars to professional vehicles such as ships and aircraft.
The abbreviated name of such a technique looks like FLS. The FLS device is necessary for the most accurate measurements of the fuel column in the tank. Taking into account the readings provided by the sensor, the program is able to calculate the following items:
There are several FLS subtypes on the market. For 2020, the most popular subtypes among buyers:
The float type is installed in the tank in the order of the factory. The measured data are displayed on the corresponding screen on the control panel. Depending on the configuration of a particular car, the location of the screen and the amount of data vary. FLS of this category does not differ in accuracy indicators, the float displays only an approximate analysis. Drivers with experience in operating such a meter claim that float deviations reach up to 30% in terms of indicators.
The category of capacitive and ultrasonic meters is considered the most accurate. To acquire such a device, the car owner needs to purchase a specific model and pay for installation in the tank. The cost of equipment in this category is an order of magnitude higher than the average price of a float, and installation will also require financial investments. For the money spent, the driver will receive an accuracy with deviations not exceeding 2%.
A similar spare part is integrated into the car system in the factory order. The location of the part is inside the fuel tank. The principle of operation is shown in the name of the part: the position of the sensor is regulated by the position of the fuel inside the container. The most common materials for this part are plastic or metal alloys. This part is divided into 2 subtypes:
The sensors are directly connected to the vehicle's on-board system. With a mass connected to the FLS and a de-energized power supply system of the machine, measurements are impossible. It is important to consider this for drivers who park their cars for a long time, because in such situations, the fuel drain will not be fixed. To avoid this situation, just connect the meter directly to the battery.
The model is notable for its miniature dimensions and wide functionality. Also, the float will protect the pump from excessive dryness and help in automating the operation of filling and draining the tank. The model is resistant to liquids such as bubble, length is 8 cm, diameter is 2.8 cm.

This sensor performs standard data analysis regarding the level of the fuel inside the tank. Made of stainless steel, connected via a 2-wire circuit, protected from moisture in accordance with the ip65 standard.
“The device does the job, but it's better in this category. The functionality is ascetic, suitable as an intermediate option. I recommend it to anyone looking for a temporary fuel gauge! ”.
Meters of this category are arranged according to the principle of emitters type devices. A wire is attached to the sensor that transmits information to the tracker (GPS). The structure is located on the outer wall of the tank. It is important to understand the principle of ultrasonic FLS analysis. The device generates a wave pulse (ultrasonic type), which is directed directly into the liquid, overcoming the wall of the container. Reaching the point of contact between air and liquid, the signal is reflected and recorded using a meter. The calculation of the indicators of the volume of fuel is based on the time spent on the reflection of the pulse.
The accuracy of such a technique is an order of magnitude superior to float devices, but a number of specifics must be taken into account. These specifications include the following points:
In addition, the installation of this type of appliance will require professional intervention. It is not recommended to install the ultrasonic equipment yourself.
This model is available for sale at a price of 8.5 thousand rubles (on average), installation will require from 3.5 to 6 thousand rubles. The model is notable for the fastening technology, which eliminates the drilling of the tank. The manufacturer excluded direct contact of the device with liquid, and also provided this instance with technology that excludes fire hazard. Users note the high accuracy of the analysis and the ability to connect the device to both Glonass and Gps.
“An excellent device, it makes fairly accurate measurements. The absence of drilling gives additional tightness, the sensor does not come into direct contact with the liquid. I recommend to everyone who is looking for a quality FLS! ”
A wide range of devices of the company for different categories of equipment is noteworthy. Apparatuses for agricultural machinery, professional transport, cars are available under this brand. For convenience, the model is equipped with a centralized data collection system that allows you to record any operations related to refueling or fuel consumption.
“Not a bad device, accurate measurements, convenient control system. While this technique can be purchased for less, the model exhibits robust quality worthy of the price tag. Would recommend to anyone looking for a reliable sensor! ”
The model in most aspects corresponds to its predecessor (Uzi-0.8), but taking into account the correction of imperfect mechanics. The improved version of the sensor from the Sensor has increased in price by 4 thousand rubles. and costs from 12 thousand rubles (on average). For this price, the user receives an improved ultrasonic control system and a number of guarantees from the manufacturer. With the appropriate connection, the sensor is capable of autonomous operation for up to 30 days, which is useful for drivers stopping for a long parking.
“I bought this model because I often stay for long periods. For such events, it is necessary to have a fuel control device, because plums occur regularly without my knowledge. I recommend to everyone who is looking for a FLS with autonomous operation! ”
The capacitive device (electronic) is placed in the tank depending on the customer's wishes. This category of meters guarantees the highest analysis accuracy. In addition, the owner of such a device has access to information regarding refueling, unintended drains. The architecture of the device consists of tubes connected to the main condenser. The tubes connect to the capacitor board in the upper compartment. The gap between the tubes is required for filling with liquid. The capacitor unit is powered by electric current. The resistance (specific) values of fuel are an order of magnitude lower than those of oxygen. Based on this, small volumes of fuel are reflected in the charging rate of the capacitor unit.
The electronic board of the FLS inside the tank calculates the time for charging. Based on the information received, the meter calculates the height of the fuel column inside the tank (as well as inside the condenser unit). The measurement system is connected to a tracker (GPS). The device transmits information about the analysis directly to the tracker. Data flow is user-regulated. Submission in real time and in delayed order is allowed.
A capacitive sensor will provide the most accurate analysis results, it is allowed to use the corresponding standard with third-party equipment. Users note the device's reliability, user-friendliness of the interface and high measurement accuracy.
