Three ports at the top and bottom of the column can be connected to the process loop or sealed off with a cap. A ruler allows simple visual level measurements. Pressure ports allow for the measurement of the pressure at the bottom and at the top of the column. A safety valve prevents the pressure from exceeding a safe limit. The column features an industrial flange that can house an optional level sensors and it contains a stainless steel baffle plate to reduce turbulence at the bottom water intake. Equipped with a bubbler tube to infer the level of fluid in the column. The large-diameter column has a capacity of 30.4 liters (8.0 gal).The small-diameter column has a capacity of 7.6 liters (2.0 gal) and can be used to create interacting second-order processes when connected to the large-diameter column. 1 Large diameter 582394 2 Small diameter 582395 3 Upper Tank Tank made of heavy-duty polyethylene that is used to create non- interacting second-order processes and is designed to be installed on the top of the Process Workstation. It features five connection ports. It can be used by a single team of students at a time. Order no. 588307 4 Chemical Tank Rectangular carboy designed to contain solutions and dispense chemicals to the process. It is equipped with dripless, quick connectors, a check valve and a faucet. Order no. 588436 5 Air Tank (Small) Robust pressure vessel designed to contain pressurized air. It features two pressure ports each equipped with a quick-connect fitting (1/4 inch) and a graduated hand-operated valve. The tank is coated to resist corrosion and is tested to SAE J10 compliance. Order no. 588313 6 Air Tank (Large) Robust ASME-compliant pressure vessel designed to contain pressurized air. It features two pressure ports equipped with a quick-connect fitting (1/4 inch) and a graduated hand-operated valve. Order no. 588312 7 Electrical Unit Module that features a lockable safety switch, a power transformer from line level to 24 V dc, and all the necessary inputs and outputs in both a safety cable version and in a terminal block version. 120 V, 60 Hz 592680 220 – 240 V, 50 – 60 Hz 592681 8 Pneumatic Unit Module that features an activation switch to quickly turn on or off the air supplied, an adjustable low-range pressure regulator (0 to 200 kPa (0 to 30 psi)) with its output air port, and an adjustable high-range pressure regulator (0 to 700 kPa (0 to 100 psi)) with its output air port.
