  • ULTIMHEAT : Paddle flow switches, reed switch contact; external brass body. Type R1V

    Paddle flow switches, reed switch contact, external brass body Type: R1V
    Size and pressure Flow sensing:
    Cleavable paddle
    Mounting:
    ¾” BSPP brass union nut
    Contact:
    Reed switch, close on flow rise
    Electrical rating Mounting position Type
    PN25 R1V
    DN≥15
    Main uses: General application in flow detection. Recommended mounting position is on horizontal pipes, but can be mounted in any position. For liquids flow detection on dia. 15 to 100 mm pipes. Body and union nut in brass for improved mechanical strength and pressure resistance. Connection box with terminal block or connectors, and detection point adjustment screw
    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.
    Usable for industrial applications in non-corrosive liquids. Must not to be used for liquids containing magnetic particles or high viscosity liquids, which block the movement of the pallet.
    Adjustment:
    - By cleaving the paddle
    - Fine adjustment by screw driver on internal dial
    Paddle shaft: Titanium, providing an outstanding corrosion resistance, and improved mechanical live
    Main housing material: Brass
    Paddle: Polypropylene, 15 mm width, with 4 sections, numbered 1 to 4, can be cleaved for adjustment to pipe size
    Pipe mounting: Nickel plated brass union nut,¾ BSPP, mounting on ¾ BSPP male thread with gasket.
    Recommended torque: 10±1 Nm
    Gasket: NBR
    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 brass, PPO and titanium
    Nominal pressure at 20°C: 2,5 MPa (PN25)
    Liquids temperature range: 5 to 100°C (Do not withstand water freezing inside pipe)
    Ambient temperature range: 5 to 80°C
    Ingress protection: IP65
    Calibration tolerances: +/-15% (on paddle operating force at end of paddle 1)
    Electrical connection:
    Standard:
    IP64 connection box, with screw terminal connection block, M16x1.5 ISO cable gland
    Options:
    - Connection box with EN17530-803-A (DIN43650-A) connector
    - Connection box with IEC947-5-2 M12x1 4 pins connector
    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 13.5 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
    Important notice: In the case of plastic pipes (PVC, PE), the DN (nominal diameter) corresponds to the outside diameter and wall thickness is variable depending on the application. This must be taken into account to avoid blocking the paddle. In the case of metal pipes, the inner diameter corresponds to the DN. Flow values data are for tubes whose internal diameter corresponds to DN.
