AstralPool – Flow Sensor with Cable for Controller 3 Plus pH-Chlorine

This is the genuine AstralPool replacement flow sensor with cable for the Controller 3 Plus pH-Chlorine (SKU 57142). The flow sensor monitors water circulation through the probe holder assembly and signals the controller when flow is insufficient, protecting your dosing system and pool water quality. It corresponds to position 11 in the official Fluidra exploded view diagram for the Controller 3 Plus pH-Chlorine.

Compatibility

This flow sensor is designed exclusively for the AstralPool Controller 3 Plus pH-Chlorine (parent unit SKU 57142). It is not a universal part — always verify your controller model before ordering. If your unit is a Controller 1 Plus, Controller 4 Plus, or any other model in the Controller range, please check the relevant spare parts list to confirm the correct sensor reference.

Why Genuine Matters

The Controller 3 Plus pH-Chlorine relies on accurate flow detection to trigger its low-flow alarm and safely pause dosing pump operation when circulation is inadequate. A genuine AstralPool sensor ensures the correct electrical signal, connector type, and cable length for seamless integration with the controller’s electronics — keeping your water treatment readings reliable and your chemical dosing safe.

Installation

The flow sensor fits into the methacrylate probe holder assembly of the Controller 3 Plus pH-Chlorine and connects via its integral cable to the controller unit. Replacement is best carried out by a qualified pool technician familiar with the Controller range. Always isolate the unit from the mains power supply before beginning any work on the probe holder or sensor components.
