/ 137 FUEL MEASUREMENT SYSTEM CALIBRATION AVL Fuel Reference is an effi cient cali��ration system that provides you with a simple way to check various types of fuel consumption measurement devices, including the way they are set up on the test- ��ed. ��uality assurance, ISO cali��ration, periodic verifi cation, and calibration according to UN ECE R49 and US EPA 40 C.F.R. part 1065. Depending on your requirements, it is capable of reducing time and effort for calibration (including testbed installation) to as little as 60 minutes. In order to increase the effi ciency of the engine test fi eld, it is also important that results from different testbeds are comparable. MEASUREMENT PRINCIPLE The Fuel Reference exists in two versions: one based on the PLUtron measuring principle and one based on the Coriolis measuring principle. For further information, please refer to page 130/131. APPLICATION An AVL Fuel Reference unit is typically connected to a fuel measurement system instead of an engine. It compares the fuel consumption value of the fuel measurement system with the sensor value of the AVL Fuel Reference. Within the software of the AVL Fuel Reference, various test runs with different �� ow rates and measurement times can be parameterized. For performing the test run, the operator is guided by the software to manually or automatically adjust different �� ow rates for the cali��ration points. The result�� high accuracy down to low �� ow rates due to massively increased measurement resolution of the AVL PLUtron™ sensor. BENEFITS AT A GLANCE • Applicable to the entire AVL fuel consumption portfolio �� High resolution at low �� ow rates with the AVL PLUtron™ sensor • Calibration of the entire fuel consumption measurement chain (measurement device and testbed installation) • Compliance with all statutory guidelines and standards (ISO, US EPA 40 C.F.R. Part 1065 and UN ECE R49) • Overall calibration effort is reduced to as little as 60 minutes • By returning fuel to the measurement device or fuel supply system, the calibration of measurement devices is done without wasting fuel AVL Fuel Reference 2 1 6 3 4 5 Piston displacement Sensor C1 Coriolis Force Sensor C2 Signal Density Mass Flow C1 C2 t Flow 1 Inlet 2 Gear meter 3 Piston sensor 4 Magnetic sensor array 5 High-power magnet 6 Outlet
