Trip points are selected by adjusting a 16-position switch as shown in Table 1.
This feature provides the ability to change trip point settings predictably, accurately and reproducibly
without the use of complex instrumentation.
See Section 7 for instructions on selecting trip points.

Optional potentiometer provides fine tuning capability
If your trip point must be set with finer control than is provided by the 16-position switch a
potentiometer provides the adjustment you need. This potentiometer can be adjusted from 7 o’clock
t
o 5 o’clock positions. Refer to Section 7 for instructions on selecting trip points.
Note
Elbows and other devices that induce swirling motion in the flowing liquid that are installed
within a distance of approximately 10 x the ID of the inlet port reduce the linear velocity
of liquid through the flow sensor.
When such devices are present the actual flow rate through the flow sensor may be HIGHER
than is suggested in Table 1.
