Main uses: Water flow detection on water pipes
Functional principle: Balanced paddle, perpendicular to the main flow, actuating a micro- switch. Flexible elastomeric gasket between paddle and electric switch
Main housing material: PPO, fiber glass reinforced, usable with potable water.
Paddle material: Polypropylene, resistant to ozone and water disinfection products
Paddle gasket: Santoprene, resistant to ozone and water disinfection products
Electrical rating: 5A resistive, 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 ½"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: 3 x 0.75 mm² cable, PVC insulation, style H05VVF.
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 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 paddle.
Accessories: 1/2" female PVC saddles forDN40 to DN100 (OD) PVC pipes, and other fittings: see last section of this catalogue
Options: cable with connector or terminals, other cable length, paddle type B (see type R1B)
