Fuel Consumption Measurement With Pulsating Flow

This paper describes the impact of pressure pulsation on a system for fuel consumption measurement. The generation of pressure pulses by the injection pump(s) on the low pressure side of Diesel engines for power generation, ship propulsion or rail traction is described. Pressure values at the location of the fuel consumption measurement system are shown. Along with measurement results of the dynamic pressure variation over a flowmeter. The relation between pressure variation and the pulse output of the flowmeter is presented. These measurements quantify the velocity variations of the fuel. With help of the measurement results, the reason for temporary reverse flow is explained. We present a system for engine related fuel consumption measurement that withstands the impact of mechanical force caused by pressure pulses, which follows the velocity variation of the fuel and which indicates and calculates short-time reverse flow to achieve an accurate measurement result.
