For practical installation, most flow meters (расходомеры) follow one of three primary connection schemes found on Rasxodomer.org :

: Uses two chambers to measure the difference between fuel supply and return lines, which is essential for modern diesel engines. Advanced Sensor Research

: Installed before the fuel pump.

: For a non-traditional approach, the Detailed Digital Fuel Indicator (DDFI) uses IR sensors to detect levels based on light absorption. It boasts a ±5% accuracy improvement over traditional float-based systems.
