The unique fact is that mounting works have been supervised by specialists of the official VOLVO service center in Italy. They checked if DFM installation causes any impact on engine operation and performance.
The trial running tests of the mounted devices were successful for all engine operation modes even in heavy conditions of mountainous terrain. Obtained measurement accuracy values have once again confirmed high quality of Technoton fuel monitoring instruments.
VOLVO experts with an own experience made sure that DFM fuel flow meters do not effect operation of engine fuel supply system.
