The unit is designed to measure even e��tremely 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 uni��ue dynamic measurement capa��ility and minimizes temperature in��uences. As a stand-alone ��ow measuring unit, AVL SORE includes a density meter, a data ac��uisition module and ��e��i��le 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 fre��uency 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 contri��uting to efficient engine testing.
