All stainless steel paddle flow switch, 16A snap action switch,
3/4" male thread
1: Removable paddles kit A, B, C, D, E
2: Stainless steel body and enclosure
3: Microswitch
4: Operating force calibration screw
5: Stainless steel bellow
6: Centering pin and force measurement point
7: Nylstop screw
Main uses: Water flow detection on water pipes
Functional principle: Balanced paddle, perpendicular to the main flow, actuating a micro-switch. Flexible stainless steel bellow
between paddle and electric switch.
Enclosure: stainless steel 304, IP69K, IK7.
Mechanism: 100% stainless steel.
Paddle material: Stainless steel .
Electrical rating: 16A resistive, 4A inductive, 230V alt. 50.000 cycles.
Electric contact type: SPDT, open or close by flow rise.
Compatible liquids: Use in clean water, drinking water and liquids compatible with stainless steel.
Nominal pressure at 20°C: 1MPa (PN10) .
Nominal diameter: Can be used on 32mm internal diameter pipes and above.
The paddle has 5 parts of different lengths allowing to use it on various pipe diameters. Tightening is made by a vibration resistant Nylstop nut.
Recommended mounting position: Vertical, with paddle downside. Other positions are possible, but with a change in the calibration value related to the paddle weight.
Water pipe connection: Male thread 3/4"(BSPP) and NBR gasket. Must be used on a BSPP 3/4" female fitting perpendicular to
the main pipe.
Recommended torque: 14N.m
Liquid temperature range: 5 to 95°C.
Ambient temperature range: 5 to 85°C.
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 32mm, to avoid blocking of the paddle.
Accessories: 3/4" female PVC saddles for DN40 to DN100 (OD) PVC. pipes, and other fittings: see last section of this catalogue.
Options: Special paddles and calibration at specified values.
Note: In case of modification of the paddle set by the user, it is important to tighten correctly, with a minimum torque of 1.2 Nm,
the paddle holding M4 Nylstop nut.
Mounting on various pipes diameters
