DFM Marine fuel flow meter installation on Komatsu PC1800 excavator

Komatsu PC1800-Hydraulic Excavator has two engines: front and rear. On each engine single a couple of DFM Marine fuel flow meters for heavy machinery is installed. Differential and for pressure mounting scheme of flowmeter installation in the fuel line of a career excavator. Both couples of DFM Marine CCAN operate in differential mode. Master-flowmeter receives data on instant fuel consumption from slave-flowmeter and calculates the value of the differential fuel consumption (the so-called built-in function “computer consumption”). Data, transmitted to telematics unit (GPS tracker):

• Instant differential fuel consumption
• Total differential fuel consumption
• Fuel consumption in supply line (Master-fuel flow meter)
• Fuel consumption in return line (Slave -fuel flow meter)
• Operating time of each engine in  “Idling”, “Optimal”,  “Overload” mode
