Fuel consumption is measured by the KVM 6 based on the Coriolis principle or Coriolis force, which is part of inertia force. A Coriolis mass flow meter (CMD) measures not only the mass flow of the medium to be measured, but also directly measures its density and temperature by comparing phase shifts. In conjunction with the integrated, highly precise conditioning unit, the KVM 6 allows for precise, continuous and dynamic measurement of fuel consumption (mass flow) on running engines.
Integration and structure
A variety of interfaces, such as analogue 0 – 10 V and CAN, are available to integrate the measurement device into the test bench environment. The KVM 6 is completely free of non-ferrous metal, making it suitable for consumption measurements of diesel fuels with organic content of up to 100%, and petrol fuel with up to 100% ethanol or methanol content. It has integrated regulation for forward and return fuel flows. The forward flow pressure can be adjusted to values within a range of 20 kPa to 600 kPa, and the return flow pressure within a range of 15 kPa to 600 kPa.
