The SeaSide Automation PW-FLOW10 is a Flow Sensor Detector with a 10' Cable compatible with a Poolwarden Chemical Controller. It is a 1/4" Cable. The PoolWarden can do everything a MiniWarden can do plus it is available in a Single or Dual ORP/pH/Temp controller with optional Free Chlorine via our TrueDPD colorimetric residual reader that not only feeds sanitizer and pH control, but can also control heaters with 2 daily set points for heaters, backup sanitizers, acid and CO2 control, automated enzyme and de-foamer feed with 2 auxiliary relays per pool that can be dry contact or incoming 110/220 VAC. Cyanuric Acid ORP offset programming is standard to help maintain more consistent chlorine levels in pools with cyanic acid. It can be used with Chlorine or Bromine.
