The unit is designed to measure even etremely small fuel ow rates and very low supply pressure on carburetor gasoline engines without return ow. The PLU measuring principle avoids interference with engine performance p 0 in a very large ow range. Installation close to the engine gives the PLU 110T ow meter a uniue dynamic measurement capaility and minimizes temperature inuences. As a stand-alone ow measuring unit, AVL SORE includes a density meter, a data acuisition module and eile interfaces. MEASUREMENT PRINCIPLE The PLU positive displacement meter combines a servo-controlled gear counter with a dynamic piston sensor. A gear meter (2) driven y a servo motor 7 with encoder 8 defines a geometric volume to pulse freuency ratio when gear rotation is adjusted to media ow. A ypass 5 ensures zero pressure difference p 0 etween inlet and outlet, preventing leakage ow. Flow changes immediately displace / 138 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 contriuting to efficient engine testing.
