High-precision fuel level sensors (FLS, also meters or sensors) of the Escort brand are designed to determine the filling level of petroleum products in fuel tanks, reservoirs and storage tanks. The '''TD-600''' meter (sensor) is used in transport technology as a fuel level meter, in industry - as a level meter for any light petroleum products. Escort FLS measurement type is capacitive. Its readings are based on the dielectric constant of the medium in which it operates; in this case, the medium is various types of light petroleum products (gasoline, diesel, kerosene, motor oil). | High-precision fuel level sensors (FLS, also meters or sensors) of the Escort brand are designed to determine the filling level of petroleum products in fuel tanks, reservoirs and storage tanks.

===== '''<big>Ladder shape tank's tank calibration</big>''' ===== | |||
When calibrating, it is necessary to create two tables, one for "'''FLS 1'''" and the second for "'''FLS 2'''" | |||
Let's assume that the calibration step is 10 liters. | |||
At the beginning of calibration, when the fuel is in the "'''Red Zone'''", the level changes will only occur on "'''FLS 2'''", so we directly add calibration steps of 10 liters to the table for "'''FLS 2'''". | |||
When the fuel is in the "'''Yellow Zone'''" changes will occur on both "'''FLS 1'''" and "'''FLS 2'''", during this period we record changes in both tables with half a step, that is, we also fill in 10 liters, but we record 5 liters in the table of each sensor. | |||
When the fuel is in the "'''Green Zone'''" the changes will only occur on "'''FLS 1'''" so we directly add calibration steps of 10 liters to the table for "'''FLS 1'''". | |||
On the platform "'''FLS 1'''" and "'''FLS 2'''" are started as separate sensors with their own tables and then a third virtual sensor is created with the sum of liters for two sensors, an example of starting two FLS on the platform is shown [https://docs.google.com/document/d/14p9GYmY0D1Wjz0ZfJXO-soVfxRBP7EiY7TgibD6vmZQ/edit?usp=sharing in this instruction.] | |||
