AVL PLU131 Flow Measurement Systems AVL PLU131 Flow Measurement Systems are high-precision flow meters and flow measurement systems for injector, pump or control valve characterization in production, R&D and engine application.
AVL provides a large spectrum of flow sensors and system solutions for these tasks with either continuous flow rate metering or injection quantity measurement.
R&D applications focus on component characterization and validation under a wide range of operation conditions.
Injection quantity measurement and injection rate analysis on component and system test benches. The most prominent group of test objects is fuel injectors (CR, GDI, Port Fuel Injectors, Unit Injectors, SCR Injectors etc.; solenoid and piezo) and fuel injection systems.
Injector testing includes injection quantity characterization versus parameters as energizing time, pressure or temperature (Q(ti,p,T). But it also comprises analysis of needle movement and timing (open and closing) as well as injection rate shaping etc.
Injection system testing investigates multiple injector interaction in a complete engine injection system. Pressure wave compensation, for instance, investigates mutual influence on flow characteristics depending on pressure and engine speed.
Component manufacturing requires quality control, adjustment or calibration of mass products like injectors, pumps, control valves etc. Sample checking or 100% control of flow characteristics is mostly realized via continuous flow measurement where short measurement time and high reliability are the most important features.
