Definition and purpose of the sensor
High-precision fuel level sensors (hereinafter referred to as "FLS" or "sensors") of
the Escort brand are designed to determine the filling level of petroleum products in
fuel tanks, reservoirs and storage tanks. Sensors TD-150 and TD-500 are used in
transport equipment as a fuel level meter, in industry - as a level meter for any light oil
products. Type of measurement FLS Escort - 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 oil products (gasoline, diesel, kerosene, motor oil).
More detailed specifications are presented in the technical data sheets of the
devices (access via the links: TD-150

Basic terms and concepts
Fuel level sensor (FLS) - a device designed to measure the fuel level.
Serial number - a code consisting of a series of letters or numbers assigned to a
product (sensor).
CNT - an oscillatory circuit, thanks to which the basic level of filling the measuring
tubes of the sensor with fuel is calculated. This level is converted to a final value
determined by the data interface.
Data transfer protocol - is a set of specific rules or logical-level interface conventions
that governs the exchange of data between various programs or devices. In the case of
TD-150 and TD-500 sensors, the main transmission protocol is LLS.
Data transfer mode - is a kind of border between two objects or nodes, which are
regulated by a special accepted standard and implemented using established
methods, tools and rules. The following modes are typical for TD-150 and TD-500:
RS-485 (Passive and Active), Analog, Frequency, RS-485 Modbus, Pulse. The names
of the modes are determined by the interface through which the readings are
transmitted.
