'''''Data transfer protocol''''' - a set of specific logical-level rules or conventions that govern the exchange of data between different programs or devices. For TD-150, the main transmission protocol is '''LLS via the RS-485 interface'''. The TD-500 sensor also supports '''MODBUS''' protocol, [[MODBUS ТД-500|description]].

'''''Navigation terminal''''' -  the main element of the system for monitoring the operation of transportation carried out by means of satellite communication. Without it, it is impossible to control transportation, to determine the coordinates of the vehicle location. It collects information from sensors and on-board system of the vehicle, and then transmits it to the device/server, which belong to the controlling specialist.

Without it, it is impossible to control transportation, to determine the coordinates of the vehicle location. It collects information from sensors and on-board system of the vehicle, and then transmits it to the device/server, which belong to the controlling specialist.

If this error occurred after the start of operation of the sensor, it means that most likely these impurities got into the sensor tubes from the tank and in this case it is also necessary to flush the tank.
If this error occurred after the start of operation of the sensor, it means that most likely these impurities got into the sensor tubes from the tank and in this case it is also needed to ensure that the tank itself doesn't contain any contaminations.
