Operator's Manual
GENERAL DESCRIPTION
The ARO® Automatic Dewatering System (ADS) offers
automatic on/off controls of air operated diaphragm pumps.
The ADS has a Liquid Level Sensor (LLS) which produces a
pneumatic output signal as the fluid level in an unpressurized
vessel rises past a predetermined level and stops the signal as
the fluid level falls past a lower predetermined level.
This pneumatic signal actuates the Pneumatic Controlled Valve
(PCV) in order to open the air line and start the diaphragm
pump. The liquid level range can be set by changing the loca-
tion of the tail ends of the "High Level" and "Low Level" sensing
tubes.
