1.0 Introduction
1.1 Operating Principles
The Model 464 Electronic Control Unit controls the supply of compressed gas
to pneumatic pumps. Drive (pressure) and vent periods are cycled to provide
water flow. During pressurization periods, water is forced into the sample tubing.
The vent period allows water to re-enter (recharge) the pump. Cycle repetition
may be controlled manually or automatically using pre-set pumping rates.
