How capacitive fuel level sensors TD-BLE work
The fuel level sensor measures the level of the fuel in the tank. It has two tubes that are placed inside the latter. They measure the dielectric permittivity of the liquid between themselves and register any changes in its level. The level data is then processed and transmitted to a GPS tracking device. This way of monitoring essentially provides means to control the fuel consumption, which is the objective of any fleet manager.
Usually, the GPS tracker is installed in a vehicle’s cabin and the sensor is connected to it by a cable. However, the wired sensors have several drawbacks: the installation and cabling takes up to three hours, they are easy to sabotage and it is easy to break the terms of their warranty. Overall, installing and using them can be a headache.
Escort company was among the first to identify the need for a better solution and came up with an innovation – wireless Bluetooth fuel level sensors. Its wireless nature is the main advantage of the TD-BLE: no need to worry about cabling and damage to wires.
