Rev. 2021 - V17
Mechanical paddle flow monitor
RHEASREG
®
SW
with switching output, in an impact-resistant plastic housing, with stainless-steel paddle, for flow
monitoring of liquid and gaseous, non-aggressive media in pipes, hydraulic systems of ¾'' through ½'' to 8'' diameter. The flow sensor is used as a
flow controller or low water alarm, e. g. for pumps in oil and cooling circuits, cooling systems, evaporators, compressors and heat exchangers,
with brass or stainless-steel bodies.

FUNCTION
Monitor: Contact COM – NO (red – yellow) breaks when flow rate drops to the preset value.
Simultaneously, contact COM – NC (red - blue) closes and can be used as signal contact.
Device is factory-set to the minimum switch-off value,
which can be increased by turning the range adjusting screw clockwise.
Installation: vertical in horizontal pipes, tee R x'' according to DIN 2950,
min. smoothing distance = 5 x pipe diameter upstream and downstream of paddle
