3.0 Mechanical Installation
CAUTION
Prior to mechanical installation, ensure that the process flow velocity to be monitored is
within the switching range of the device. Also ensure that system temperature and
pressure are within the limit of the device. See Section 2.0 ”Specifications”.
3.1 Installation General
The following general installation instructions and precautions apply to all KAL-8000
series installations:
3.1.1 The probe tip must be inserted a minimum of 3/8” beyond the
inside diameter of the pipe or duct into which it is to be installed.
Best results are obtained if the probe is inserted into the pipe or duct 1/
2” or greater.
3.1.2 In order to ensure that the sensing elements are facing directly into the
flow stream, a notch has been placed on the probe hex nut to aid in
alignment. For optimal results, the probe should be installed so that the
notch is aligned directly over the centerline of the pipe or duct.
3.1.3 In order to ensure a uniform flow profile across the probe tip, install the
probe to allow for 10 pipe diameters of straight run piping upstream and
5 downstream. This piping should be free of tees, elbows, bends,
valves, dampers or any other such appurtenances.
3.1.4 The probe should not be installed in the lower hemisphere of the pipe or
duct. Liquid and debris which collect in the lower portion of the pipe will
cause the probe to function erratically if they come in contact with the
probe.
