DFМ fuel flow meter is used for diesel fuel consumption measurement and engine operation time monitoring of mobile and stationary machinery:- trucks, agricultural, construction, utility vehicles;- railroad machinery;- small watercrafts;- diesel gensets;- burners/boilers (oil consumption measurement).Diesel fuel, mineral (heating) oil and other liquids with kinematics viscosity of 1.5 cSt to 6 cSt can be measured by DFM.DFM fuel flow meter is a tool for direct fuel consumption measurement, the data from the flow meter is used in vehicle tracking/fleet management applications for increasing operational efficiency of machinery, reducing maintenance costs (predictive maintenance) and increasing overall ROI of fleet.DFM helps to solve the following tasks:- Prevent fuel theft from fuel lines of engine- Establish accurate accounting of fuel consumption- Define real operation hours of vehicle/machine- Adopt predictive maintenance approach of fuel system- Test engine from fuel consumption point of view
