  • ULTIMHEAT : Paddle flow switches, reed switch contact, 3/4”union nut, slim design. Type R1P

    Paddle flow switches, reed switch contact, 3/4”union nut, slim design Type: R1P
    Pressure and size Flow sensing:
    Cleavable magnetic pull back paddle
    Mounting:
    ¾” BSPP plastic union nut
    Contact:
    Reed switch, close on flow rise
    Electrical rating Mounting position Type
    PN10 R1P
    DN≥20

    1: Cleavable paddle 2: 3/4” BSPP plastic union nut 3: Connection cable 4: Adjustment screw

    Main uses: 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 pipes
    Functional 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 salination 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)

    Values upon (low span end) , middle span and (high span end) calibration.

    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.
    Recommended mounting position: On horizontal pipes. Mounting in other positions slightly modify the calibration
    Water pipe connection: On male 3/4” fitting. NBR gasket is supplied with the product. Recommended torque: 7Nm
    Liquids temperature range: 5 to 80°C
    Ambient temperature range: 5 to 50°C
    Ingress protection: IP65
    Electrical connection: 2 x AWG24 (0.2mm²) cable, PVC insulation, T80°, style UL2464.
    Installation instructions:
    - Check carefully the paddle orientation: The arrow on housing must be exactly parallel to the pipe
    - A 5 mm minimum gap must be respected between end of the paddle and tube wall opposite to the fitting.
    - We recommend the use of nozzles of length less than or equal to 18mm between the gasket seat and the inside of the tube and with an inner diameter greater than or equal to 20 mm, to avoid blocking of the paddle.
    Accessories: 3/4” male PVC saddles for DN40 to DN100 (OD) PVC pipes, and other fittings: see last section of this catalogue
    Options: cable with connector or terminals, other cable length, nickel plated ¾” BSPP union nut
