The Diesel Return Flow Sensor RFS400 is a closed system four channel flow sensor that can be placed in the return flow circuit of a Common Rail diesel engine. Connected to the Automotive scope ATS5004D with ATIS software, the small return flows of four cylinders can be measured simultaneously and accurately. A graph for each cylinder shows the size of the fuel flow. Due to the closed system, no diesel is spilled, keeping the work area clean.
This video shows how to check the diesel injection system by measuring the the diesel return flow using the Diesel Return Flow Sensor RFS400 and the Automotive Test Scope ATS5004D.
