Controller provides local display in single or multi-unit network
AW-Lake, Oak Creek, Wis., introduced new PCU Series of Controllers that connect with Vogtlin or any thermal mass flow meter or controller to provide a local display of flow output. Serving as a single- or multi-channel mass flow controller with up to four channels, the PCU instruments support multiple unit networked operations. A large, high-contrast backlit display offers easy-to-read views of process variables and programmed set points for each connected device on one screen.
The PCU Series offers process control functionalities for batching, set point control, resettable dual totalizer and valve override control. Gas factor scaling allows users to set units to any fluid. Units are programmable to provide alarm status for high and low rates both visually and audibly.
Configurable from a keypad or using an RS-232 connection to a computer or PLC, the PCU Controllers offer remote readout, set point control, and data acquisition capabilities. Built-in diagnostics ensure trouble-free operation by testing system operating status, memory condition, communication adapter status, display functionality and keypad operation at every power-up.
