Type R1R Paddle flow switches

Model Number: R1R Brand Name: JPCI, ULTIMHEAT Key Specifications/Special Features: Type R1R Paddle flow switches, micro-switch contact, 1/2 BSPP male thread, and Pt100 sensorMain features:water flow detection on water pipes, with simultaneous water temperature measurementFunctional principle:balanced paddle, perpendicular to the main flow, actuating a micro- switch. Flexible elastomeric gasket between paddle and electric switch. Temperature measurement is made by a plastic pocket located under the ” threadMain housing material:PPO, fiber glass reinforced, usable with potable water
Paddle materials:Polypropylene, resistant to ozone and water disinfection products
Paddle gasket:Santoprene, resistant to ozone and water disinfection products
Electrical rating:5Aresistive, 230V AC
Electric contact type:SPDT, open or close by flow rise
Liquids compatibility:For use with clean water and liquids without chemical incompatibility with PPO and Santoprene
Nominal pressure at 20°C:1MPa (PN10)

Nominal diameter:can be used on 32 to 63 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 9 every 5mm.

Recommended mounting position:Vertical, with paddle downside. Other positions are possible with a change in the calibration value related to the paddle weight. .

Water pipe connection:Male thread 1/2” (BSPP) and NBR gasket. Must be used on a BSPP ” female fitting perpendicular to the main pipe.

Recommended torque:7Nm

Liquids temperature range:5 to 80°C

Ambient temperature range:5 to 50°C

Ingress protection:IP65

Electrical connection:

Flow switch contact:3x0.75 mm cable, PVC insulation, style H05VVF

- Pt100 temperature sensor: 3x0.22mm cable, nickel plated braided FEP insulation

Flow and temperature connection cables length is the same

Installation instructions:

- Check carefully the paddle orientation: The arrow on housing must be exactly parallel to the pipe

- A 5mm minimum gap must be respected between end of the paddle and tube wall opposite to the 3/4” 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 20mm, to avoid blocking of the pallet
