Neptune FC-1N-P-N2 Flow Checker

Feed Verification

Model FC-1 Flow Checker

The Model FC-1 Flow Checker output provides vital information for watertreatment programs requiring feed verification to manage chemistry and monitor drum inventory

• The flow checker mounts directly to the discharge of PZ, PWM, PWP and PWT metering pumps.
• The flow checker is an oval gear flow meter which measures the pump output and transmits one pulse for each 1 ml of flow.
• Connect the flow checker output to your controller or PLC (external power supply required).

† Not available for larger models

Liquid-End Materials

* Ryton: PPS — Polyphenylene-sulfide (for general chemicals)
** Noryl: PPO — Polyphenylene-oxide (for sodium hypochlorite)
