MOUNTING
The S6065A1003 and S6065A2001 Liquid Flow Switches can
be mounted in any desired position far from elbows, valves,
and filters.
S6065A1003
GENERAL
The S6065A1003 and S6065A2001 Liquid Flow Switches are
designed for monitoring flow rates in pipes employed in HVAC
applications. They are suitable for monitoring flow in water,
oil, cooling circuits, and lubrication systems. The S6065A2001
is designed for monitoring aggressive liquids.
See Table 1 for the reset and switch points for water. Data for
other media must be determined empirically.
NOTE: The arrow on the housing must point downstream.
In the case of vertical pipes, reset the range to balance the
paddle weight. To prevent malfunction caused by impurities in
the medium, do not mount the device with the housing
pointing downwards.
When using multiple paddles, the paddles must be
arranged in order of decreasing length downstream,
i.e. with the longest paddle facing the oncoming
liquid.

SWITCH-POINT ADJUSTMENT
The flow switch is factory-set to the min. flow rate. To adjust
the device to other levels, turn the adjustment screw
clockwise. Table 1 lists the reset points and switch points for
water. Data for other media must be determined empirically.

*For models with the suffix “Z,” the longest paddle must be used to
obtain the values indicated in this table. The Z = 8” paddle must be
cut to the proper length to fit into the pipe without touching the
inside.
