SY321 · Fluid Level & Flow Control Module

Integrated liquid level and flow rate control experiments

Experiments
  • Investigation of integral and proportional control behavior in fluid systems
  • Level control with dead time and time constant analysis
  • Flow rate measurement and adaptive PID control
  • Pump dynamics and bidirectional flow control
  • Valve response and fill/discharge rate optimization
  • Real-time monitoring of both level and flow simultaneously
  • Visual inspection of fluid behavior via transparent tank design
SY321
Description
    The SY321 is a compact controlled system for flow and level control experiments. Depending on the mode of operation, the system exhibits integral or proportional behavior with dead time. The storage tank and measurement tank are fully accessible and allow direct visual inspection of the controlled variables. The module features a calibrated pressure sensor for level measurement and control, plus an integrated flowmeter with adaptive digital PID controller. The self-priming, bidirectionally operating gear pump enables active filling and draining of the measurement tank. Externally adjustable valves allow investigation of practical fill and discharge scenarios.
