Asahi/America PAL-AT LiquidWatch

• Liquid Leak Detection/Location Systems for
  containment piping

PAL-AT Cable Systems and LiquidWatch Low Point
Probe Systems

• PAL-AT uses coaxial cables and probes to monitor
  for liquid leakage. The system can detect and
  locate leaks, breaks and shorts in the sensor
  cable.
• LiquidWatch is a probe monitoring system that can
  monitor up to 64 probes from a single panel. The
  probes are monitored for activation, breaks and
  shorts.

Time Domain ReflectometryTDR

• TDR is a cable measuring technology related to
  sonar and radar. By sending energy pulses down
  the center conductor of a coaxial cable and
  measuring the reflected energy to the outer braid
  a map can be stored of the cable and monitored
  for change. When change occurs the type of alarm
  and its location is displayed on the panel.

  while the LW64IS provides a UL Listed System for
  monitoring in Class 1, Division 1 Groups C D
  locations. The basic panel monitors up to eight
  probes with modules being added for additional
  probe requirements up to a total of 64 probes.

19
Asahi/AmericaApplications

• Piping - Containment piping, single wall piping,
  waste drains.
• Trenches and Trays - Under wet benches, piping
  and equipment.
• Any place leak detection is required, where a
  probe or sensor cable can be used.

20
Palcom SoftwarePAL-AT and LiquidWatch

• Palcom allows remote control of up to 254 panels
  with the ability to review TDR traces, review the
  history of each unit and to pull down a Cad
  drawing or a map of each system for location of
  leaks, breaks, shorts or probe activation's.

24
Basic design and installation considerations
25
Access Port Location

• Every 500 ft. on a straight pipe run
• Beginning of each pipe run
• Beginning of every branch line
• End of every branch line
• End of every pipe run or trunk line

26
Access Port Location

• Every 90 degree change in direction 150 ft.
• Small annular space and other considerations may
  make it necessary to place access ports closer
  together.

27
Pull Ropes

• Order must specify that pull ropes are required
  on all pipe and fittings.
• Inform contractor that small (1/8) braided wire
  is required to make welds in the pipe run, and to
  make a continuous line for cable pulling.

28
Pull Ropes

• Inform contractor that a continuous pull rope
  will be required between access ports.
• A hollow braid rope facilitates easier
  installation than a twisted braid.

29
Cable and Connectors

• Cable is pulled when pipe installation and
  testing is complete.
• Confirm that the contractor has the necessary
  tools to install the connectors. Most
  electricians should have the required tools, but
  its always a good idea to check.

30
Cable and Connectors

• After cable is pulled A/A will provide factory
  trained technicians to train the contractor on
  connectorizing the cable.
• Although this is straight forward, it is where
  most of the mistakes are made.
• It cannot be overstated how critical proper
  connectorizing is to a successful installation.

31
Panel Commissioning

• Upon completion of cable pulling, connectorizing
  and panel installation, A/A will send two
  technicians to the job site for start-up and
  commissioning of the system.

Services Offered
33
Engineering

• Complete Engineering Services
• Assist the customer with project take-offs.
• System layout.
• System mapping for project documentation and
  storage.
• Phone support with the ability to offer direct
  modem support if system is capable.

34
Engineering (cont.)

• Factory trained field support for the instruction
  of construction personnel in installing the
  cable, cable connectors, probes, relays, or any
  other hardware of software accessory.
• Field Technicians for the start-up and
  commissioning of the system itself. Includes
  mapping of system so that there is a record at
  the Asahi/America office.
• Field Technicians for any other support the
  customer may need.

35
Field Technician Services

• Policy of the Field Technicians will be similar
  to the one in place now. The difference being
  that there will be no freebies for the Leak
  Detection services. The industry is currently
  supporting the cost of these technicians.
• There will usually be two trips to a job site for
  the technicians, the first for the cable
  connector training and the second for the
  start-up and commissioning of the system.

36
Field Technician Services (cont.)

• The certifying of the installers, with a
  certification card upon completion, is currently
  under consideration.
• There will be two technicians on site for the
  start-up and commissioning process. This is
  mandated by the complexity of the mapping of the
  system, as well as the importance of the quality
  assurance of the installation. Since we are
  taking a more active role with the customer
  support we need to have some oversight in this.
