AVL PRODUCT DESCRIPTION

GASOLINE CONSUMPTION WAY OF MEASURING

AVL GAS MASS CIRCULATION METER

Explanation The AVL Fuel Mass Flow Meter is a excessive precise and continuous fuel consumption measurement system, which is often used worldwide at almost all engine test mattresses where machines of a optimum consumption of 125 kg/h are analyzed. The system sticks out for a extremely high accuracy also because of the do it yourself design it is usually combined with existing conditioning devices. The gas system AVL Fuel Mass Flow M enables a high precise gas consumption dimension also in low circulation rates and short dimension times. With a high accuracy and reliability mass movement sensor the fuel usage is determined constantly and by means of direct mass flow way of measuring in kg/h. The density does not have to be determined beyond the direct dedication of the gravimetric or particular fuel consumption like in volumetric measurement methods. The energy consumption can thus always be determined to an accuracy of 0. 12% for the whole program under true test pickup bed conditions. With the FlexFuel version, up to completely alcohol and biodiesel may be measured.

AVL PRODUCT EXPLANATION

Function Summary • • • Sign of gas consumption in kg/h, l/h, l/h (API) Indication of fuel density in g/cm³ Measurement and indication with the actual gasoline consumption in a way of measuring frequency of max. twenty Hz • • • Average intake for pre-selected measuring period or pre-selected measuring excess weight Total/interval consumption for established measuring time Running typical calculation with additional signal of regular deviation and measurement uncertainty • • • • • Complete automatic accuracy and reliability check and calibration Fast and useful fuel change Indication of error and status survey Service span display Computerized fuel venting

Application The fuel system AVL Fuel Mass Stream Meter permits high exact, continuous mass-flow measurements likewise at low flow prices and short measurement moments.

Benefits • • Dimension accuracy of 0. 12% through immediate mass movement measurement Open up continuous way of measuring system (no additional pressure increase in the measurement routine e. g. due to heat changes, …) • • Rapid measurements even at the lowest amounts of consumption The highest level of reliability and common suitability to the requirements of modern measurement strategies and injection systems • Via a single cylinder through to a 600 kW large engine with 1 sensor and measuring program • Built/in accuracy examine and calibration according to ISO 9001 with alternative: calibration product

AVL PRODUCT DESCRIPTION

Specialized Insight The measurement program stands out to get simple assembly at all gasoline or diesel powered injection systems and it is therefore universally applicable. This is certainly achieved through the use of a exclusively developed pressure control program that makes vehicle-like conditions feasible on the test out bed. The additional measurement of the fuel density can be used intended for quality control or investigations for the correct fuel used. The volumetric consumption data is also available. The measurement range from zero to 125 kg/h protects all engine types from a single cyndrical tube through a six hundred kW significant engine with one messfuhler and measurement system. The high powerful AVL Fuel Mass Flow Meter includes a calibration period of bare minimum three years and is therefore created to provide a everlasting availability to get the test foundation. In addition that features a pre-installed accuracy check and calibration (see choice calibration unit) according to ISO 9001 which can be performed at any time during running engine and with the original fuel.
