Paddle flow switches, reed switch contact, inside barbed tee for 1”soft tube
Main uses:Tee equipped with paddle flow switch, for spas and swimming pools applications, mounting on 1” (20 to 21mm ID) soft PVC tubes, adjustable setting.
Used on water circulation circuits to detect the passage of water or filter clogging and avoid dry running. Recommended mounting position is on horizontal pipes, but can be mounted in any position allowing an efficient air bleed.

Main uses: Tee equipped with paddle flow switch, for spas and swimming pools applications, mounting on 1” (20 to 21mm ID) soft PVC tubes, adjustable setting.
Used on water circulation circuits to detect the passage of water or filter clogging and avoid dry running. Recommended mounting position is on horizontal pipes, but can be mounted in any position allowing an efficient air bleed.
Functional principle: Balanced magnetic pallet mounted perpendicular to the flow and acti- vating a reed switch through the wall. The return of the pallet is by made by magnetic action, without spring. No seal or liquid can pass between the piping system and the electrical con- tact. Suitable for corrosive water pools and spas and salination chlorination and bromination systems. Must not be used for water containing magnetic particles or high viscosity liquids, which block the movement of the pallet.
Adjustment: By means of the adjustment screw located under the protective cover. This setting must be carried out only by professional, qualified and trained personnel, as a too low setting can produce an insufficient pull-back force and malfunction. This adjustment is designed for single use and can be sealed.
Main housing material: Polypropylene, resistant to ozone and water disinfection products, usable with potable water.
Tee material: PVC
Paddle: Polypropylene, 15 mm width
Paddle shaft: Titanium, providing an outstanding corrosion resistance, and improved me- chanical live
Electrical rating: Max 1A, Max 70W, Max 250V, resistive load. Use on inductive circuits reduces electrical rating. We recommend to protect the reed switch with contact protection device when used in inductive loads
Electric contact type: Normally open, closes by flow rise
Liquids compatibility: For use with clean water and liquids without magnetic particles and without chemical incompatibility with polypropylene and titanium
Nominal pressure at 20°C: 0.3MPa (PN3)

Liquids temperature range: 5 to 45°C
Ambient temperature range: 5 to 45°C
Ingress protection: IP65
Electrical connection: 2 x AWG24 (0.2mm²) cable, PVC insulation, T80°, style UL2464.
Installation instructions: Water circuit in spas and pools can contain air bubbles, it is important to prevent them stagnate in the unit of measure and originate false flow meas- urement. Therefore the air bleeding orifice must be located above and connected
Options: cable with connector or terminals, other cable length.
