The contains everything that is needed toperform a range of single-loop process control experiments in conjunction witha PC.
It includes a variable volume process tank, ahot water tank with electric heater and indirect heating/cooling coil, a hotwater pump, two non-dedicated pumps, three on/off solenoid valves and aproportioning valve. The instrumentation includes temperature sensors, twodifferential water pressure sensors, a mechanical level sensor (float switch)and an electronic level sensor (conductivity). The inlets and outlets of thevarious pumps, valves and tanks incorporate self-sealing quick releasefittings. This allows the configuration to be quickly changed, offering a widevariety of different loops.
