Electronic Capacity Control (ECCA) for Metering Pumps
AcuFlow’s Electronic Capacity Control (ECCA) permits the automatic adjustment of pump capacity. Replacing the standard manual micrometer knob and mounting directly on the pump, the ECCA uses miniaturized, state-of-the-art electronic technology built around an AC synchronous motor. This permits precise actuator travel, without hunting or overshoot.
