    History of the taxi begins in ancient times. The first taxi drivers are the drivers. Example of the first taxi appeared in France in the 17th century. Originally they were riding carriages, which are unknown to organize enterprising resident of France. Taxis serve the hotel courtyard. In 1897 there were carts with a gasoline engine. In 1905, invented the taximeter and all orders are charged. The name of this device and the name of this type of matter transportation – taxis, or taxi.

    A pioneer in the production of taxis – is well-known company Renault. Read more from Andrew Cuomo to gain a more clear picture of the situation. In order to stand out cars in the city of avenues painted in red and green. And different device Body taxi, because the front of the cabin was separated from the passenger. The first mention of the Russian Empire of the cab on the car belongs to 1907. Before the October revolution in the industry of the private carting car very rapidly developed.

    However, later it was destroyed, as an accessory 'bourgeois class'. Only many years later, in 1924 the Moscow Council adopted a decision on the revival of a taxi and made the purchase of two hundred Car brands Fiat (Italy), Renault (France). Originally there were only a taxi in Moscow and St. Petersburg. In the 30s of the last century, the production of machines for taxis started with a prototype of 'GAS-A'. The number of Soviet taxi increased by 7 times. For tax rates very long time for a journey was 50 cents a mile, one hour journey – 4 rubles. 50 kopecks. At night, operated 25% margin. After the war, in the taxi were introduced distinctions: the chess strip along the sides of the body and green light. In 1957 he took the start of an era 'Volga', and continuing to this day. In our era of taxis – an important part of a city and its transport. According to statistics, every 5 people in the world used or uses the services of a taxi.

    A more accurate method is to connect to onboard GPS-controller fuel level sensor. It is also possible variants that differ in accuracy and cost. Cheapest way to connect to the standard gauge cars. At the same time as there is no interference with the fuel system. However, the error in this case is large enough (though less than the estimated method) for domestic cars with mechanical float sensors up to 20% for foreign cars 5 … 10%.

    Wear sensor with matters too. Thus, the connection is full-time fuel gauge to GPS-enable the controller with some precision control of fuel consumption and see the actual (time and place) dressings, or drains, if any. Much more accurate is the installation of fuel tank high-precision electronic level sensor. The most common types, it is capacitive and ultrasonic sensors. They have no moving parts, no wear. Accuracy of these sensors is about the same and is 1-2%, and price is much less than one complete filling of the truck. That is, if you connect to the standard sensor can see the place and time of filling or draining of fuel, in the presence of high-precision sensor can be seen – how many liters zapravlenoslito. Fuel flow.

    There is a group of vehicles, which are characterized by relatively high fuel consumption, and simultaneously move to a small area, for example – excavators, bulldozers, loaders. Another group of vehicles has a flow rate of almost (or completely) independent of speed, for example – additional engine blender or mixer refrigerator. In such cases, the fuel control You can use the flow sensor. In contrast, the level sensor, which is installed directly into the tank, the sensors are set to break the fuel system and show no fuel level, and how much fuel is "ate" engine.
