3.0 Mechanical Installation
To install the KAL-K flow switch into your piping system, proceed as follows:
3.0.1 The KAL-K flow switch can be mounted in virtually any orientation
as long as the piping is completely filled with fluid. It is recom-
mended that the unit be installed in the upper hemisphere of the
pipe when being used in horizontal piping runs. This ensures that
sediments do not deposit on the probe. It is also recommended that
the unit not be installed in the top of the pipe on horizontal runs. This
ensures that air pockets which collect in the top of the pipe do not
cause false switching

3.0.2 For optimal measuring accuracy, allow for a minimum of 5 pipe
diameters of straight-run piping both upstream and downstream of
the flow switch. This ensures that flow profile at the sensing probe is
uniform and fully developed.
3.0.3 Prior to installation, ensure that the desired flow alarm setpoint is
within the switching range of the KAL-K. Additionally, ensure that the
maximum system temperature and pressure are within the limits
specified per Section 2.0, Specifications.
3.0.4 It is recommended that a suitable thread sealant, such as PTFE
tape, be applied to the probe threads to ensure a leaktight seal.
3.0.5 Using an appropriate sized wrench, carefully thread the sensor
probe into the piping system. The probe must be installed such that,
at a minimum, the probe tip extends beyond the inner diameter of
the piping and into the fluid stream.
