Users benefit from the PLU measuring principle thanks to a large measuring range, no engine interference (Δp = 0) and extreme resistance against vibration and shock. Due to the unit’s lightweight design, small footprint and 12 V DC supply voltage, the integration into on-road and off-road vehicles with single direction fuel flow is extremely easy. In addition, an optional installation kit facilitates flow meter setup for engines with fuel return lines (e.g. diesel engines). 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 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 PLU 116H is an excellent flow meter solution for mileage accumulation applications with a focus on flexible use, simple setup, robustness and long-term stability. With large measuring ranges, medium resolution and high accuracy, its primary purpose is monitoring and total consumption measurement. A display unit (VAZ display) and a data acquisition unit (PLU 4000) are available as options for flexible use in various environments. / 138 BENEFITS AT A GLANCE • Cost-efficient sensor solution for mileage accumulation and similar applications • Flexible use and comfortable options for easy system integration or stand-alone functionality • Robust design and long-term stable calibration • No influence on engine performance (no pressure drop; Δp = 0) due to PLU measuring principle MOBILE MILEAGE ACCUMULATION CONSUMPTION MEASUREMENT 6 7 10 9 8 1 2 3 5 1 - Einlass 2 - Zahnradzähler 3 - Positionssensor 4 - Kolben 5 - Bypass 6 - Auslass 7 - Servomotor 8 - Impulsgeber 9 - Regler 9 - Signalausgang 4 1 Inlet 2 Gear meter 3 Piston sensor 4 Piston 5 Bypass 6 Outlet 7 Servo motor 8 Encoder 9 Controller 10 Signal output Available online via AVL ePRODUCTS https://shop.avl.com
