Model Number: R1P Brand Name: JPCI, ULTIMHEAT Key Specifications/Special Features: Type R1P Paddle flow switches, reed switch contact, 3/4 union nut, slim designMain features:The most simple flow switch with magnetic pull-back. Recommended mounting position is on horizontal pipes, but can be mounted in any position. For water flow detection on dia. 25 to 100 mm water pipesFunctional principle:Balanced magnetic paddle mounted perpendicular to the flow and activating a reed switch through the wall. The return of the paddle 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 salivation chlorination and bromination systems. Must not to be used for water containing magnetic particles or high viscosity liquids, which block the movement of the paddle.
Adjustment:there are 2 adjustment ways on this model

- By cleaving the paddle

- 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.

Union nut material:High mechanical strength fiber glass reinforced PA66.

The type without nut is designed for snap-in assembly on plastic and stainless steel fittings. (See last section of this catalogue)

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

Nominal pressure at 20°C:1MPa (PN10)


* Close by flow rise (L/min) of contact open at no flow position** Open by flow decrease (L/min) of contact open at no flow position. Average values for indication only. Standard tolerances±30%

Nominal diameter:Can be used on 25 to 100 mm internal diameter pipes
The paddle is cleavable and can be cut at various lengths upon pipe diameter. There are cutting lines numbered 1 to 10 every 5mm.
