Level Process Station (3503)
The Level Process station is an 8-inch diameter, 36-inch high Plexiglass cylinder with diaphragm-actuated control valve, pipe-mounted differential transmitter and I/P converter mounted on the side of the cabinet and terminated at quick-connect fittings on the main control panel. Also mounted on the main panel are the microprocessor-based controller, strip chart recorder, and two alarm lamps. A regulator needle valve controls air flow to a bubbler pipe for level measurement. In addition, at the base of the level column are two valved taps to permit connection of the D/P cell, optional manometers, low pressure gauges, and wet leg standpipe.
