The unit is designed to measure even extremely small fuel flow rates and very low supply pressure on carburetor gasoline engines without return flow. The PLU measuring principle avoids interference with engine performance (Δp = 0) in a very large flow range. Installation close to the engine gives the PLU 110T flow meter a unique dynamic measurement capability and minimizes temperature influences. As a stand-alone flow measuring unit, AVL SORE includes a density meter, a data acquisition module and flexible interfaces. MEASUREMENT PRINCIPLE The PLU positive displacement meter combines a servo-controlled gear counter with a dynamic piston sensor. A gear meter (2) driven by a servo motor (7) with encoder (8) defines a geometric volume to pulse frequency ratio when gear rotation is adjusted to media flow. A bypass (5) ensures zero pressure difference (Δp = 0) between inlet and outlet, preventing leakage flow. Flow changes immediately displace / 136 a zero-friction piston (4) in either direction. A piston position sensor (3) and a servo controller (9) provide a fast gear speed control loop keeping the piston centered. APPLICATION AVL SORE PLU 110 is used in R&D, production and engine testing. End-of-line tests for two-stroke SI engines include carburetor adjustment for performance optimization and emission standards compliance. Test time minimization is a primary target of EOL test design. Due to its dynamic measurement capability, the AVL SORE PLU 110 accelerates adjustment of power limits significantly, so contributing to efficient engine testing.
