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 activating 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 contact. 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 mechanical 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

Pressure and size
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 measurement. Therefore the air bleeding orifice must be located above and connected
Options: cable with connector or terminals, other cable length.
