Alternatively, for small numbers of cells the concrete bases may be directly on the floor. * Ability to use pre-cast concrete sections, reducing site construction time. * Generally more economic where concrete batching is readily available. Using concrete, cons: * Difficult to get levels sufficiently accurate (+/-5 mm) without using a screen layer. * Need to accurately cast-in allowances for any discharge valves or cell dump valves that protrude below the tank bottom. * Availability of concrete is often poor for remote sites. Using steel, pros: * Prefabrication offsite minimizes site installation time. * Easier to adjust site levels during installation. * Greater flexibility when allowing for ancillary items.\n Automation engineering took place at Emerson's Pudong Engineering Center near Shanghai, with Emerson technicians working with smelter personnel to integrate the DeltaV system with Rosemount instruments, Fisher valves and Fieldvue digital valve controllers, and the AMS Device Manager.
