The TFD System will detect many chemicals (chlorine, acids, etc.). If non-compatible chemical is detected in the pump head, the injector shuts off. The problem chemical must be cleaned from the pump head before the injector will re start.Additional FLEXFLO Model A-100NE features include: Digital interval timer for near infinite turndown ration; repeating interval and injection time cycles which are programmable in seconds, minutes, hours and days; accepts pulse inputs for time on per single pulse, or multiple pulses; and the A-100NE accepts 4-20mA and 0-10Vdc signal for external injection control.
