. This flow sensor is applicable for flow monitoring of liquid and gaseous non-aggressive media in
pipes and in hydraulic systems from ½'' through ¾'' up to 8" in diameter, furthermore used as flow control instrument or as water failure protection
switch, e.g. for pumps in oil circulation and cooling systems, in evaporators, compressors and heat exchangers, with brass or stainless steel body.

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
