Coupled Tanks

Product Description
Re-configurable process control experiment that enables students to perform a wide array of modeling and control-related laboratories
The Coupled Tanks system is a process control experiment ideal for teaching and research of control topics related to liquid level control.
Overview
Designed in association with Prof. Karl Åström and Prof. Karl Henrik Johansson, the Coupled Tanks system consists of a single pump with two tanks. Each tank is instrumented with a pressure sensor to measure the water level. The pump drives the water from the bottom basin up to the top of the system. Depending on how the outflow valves are configured, the water then flows to the top tank, bottom tank, or both. The rate of flow can also be changed using outflow orifices with different diameters. The ability to direct water flow, together with variable outflow orifices allows for several interesting Single Input Single Output (SISO) configurations. Further, two or more Coupled Tanks can be combined together for Multiple Input Multiple Output (MIMO) experiments.
Features

– Pressure sensors on each tank
– Re-configurable water flow pump and tanks
– Drain tap allows water from top tank to pour directly into basin
– Three sizes for outflow orifices supplied (small, medium, and large)
