4. INSTALLATION
4.1 HANDLING PRECAUTIONS
Even though the LKP Series systems are large and rugged, they should be handled with the
same care as any precision measuring instrument. Larger Measuring Heads are quite heavy,
and adequate handling equipment must be available. Severe jolts or bumps to the Measuring
Head or Metering Unit may cause movement of internal parts, and possibly a malfunction. It is
also advisable to avoid supporting the head-halves by the window insulation. The window
insulation is tough, but brittle
. Personnel involved in the installation should be experienced
with equipment of similar size and weight. They should also be familiar with the
technical terms, warnings, and instructions in this manual, and all plant safety rules, and
be able to follow these regulations.
The complete system should be inspected for shipping damage at the earliest opportunity.
Visible damage must be reported to the carrier immediately. Concealed damage (not evident
until the system is operated) must be reported to DynAmp, LLC immediately.
4.2 MAGNETIC CONSIDERATIONS: MEASURING HEAD
The LKP Series 4 metering systems are designed and built for accuracy, stability, and reliability.
However these factors may be adversely affected by the arbitrary location of the Measuring
Head without regard for magnetic fields. Secondary magnetic fields emanating from angled
sections of the bus being monitored or from other nearby buses may cause overheating.
Currents from other buses produce magnetic fields which can sometimes cause zero offsets
and errors at low current levels. To guard against these problems, a computer analysis of your
bus system should be performed. If a bus analysis is not feasible, the guidelines presented in
this section can be used as a starting point.
FREE BUS ANALYSIS
The general guidelines below should be applied only when a detailed analysis of
your bus system is not available. DynAmp, LLC will perform one detailed
computer analysis of the proposed location of the Measuring Heads within your
bus system at no charge. Generally, this is done before or at the time the unit is
ordered. In this way you are assured that your LKP Series 4 Channel OEM
system will function properly.
Whenever possible, the Measuring Head should be installed on the longest straight run of the
bus that is available in an area free of other bus structures. General guidelines requiring
consideration when installing a Measuring Head are shown in figure 4.1 (guidelines illustrated
are to be considered as the minimum required distances). If the proposed Measuring Head
location can be physically described by more than one of the diagrams (figure 4.1), a bus
analysis should be performed. For the guidelines of figure 4.1 to apply, the
bus
height-to-width
ratio should equal the
head aperture
height-to-width ratio, within ±10%. This ratio does not
affect the accuracy of the measurement, but it does affect the loading of different sections of the
Measuring Head.
