Transcript PermAlert ESP


Liquid Leak Detection/Location Systems
for piping, raised floors, semiconductor
tools, containment piping, fuel systems
and other applications
Company Profile



PermAlert is part of Perma-Pipe the largest
prefabricated – preinsulated pipe
manufacturer in the US
PAL-AT Leak Detection was introduced in
1988 and was the reason for founding
PermAlert ESP
Sales Volume of the parent corporation
(MFRI) is about US $178 million with over
500 employees worldwide
PAL-AT Cable Systems and
LiquidWatch Probe Systems


PAL-AT uses coaxial cables and probes to
monitor for liquid leakage. The system can
detect and locate leaks, breaks and shorts on
the sensor cable as well as probe activations.
LiquidWatch is a probe monitoring system
and can monitor up to 64 probes from a
single panel. The probes are monitored for
activation, breaks and shorts.
Time Domain Reflectometry
PAL-AT

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.

AT20C - Monitoring up to 2,000’ (600 m) on a single
cable
AT50C - Monitoring up to 5,000’ (1500 m) equivalent
length on a single cable
AT20K - Monitoring up to 7,500’ (2500 m) equivalent
length per cable with a maximum of two cables
AT40K - Monitoring up to 5,000’ (1500m) equivalent
length per cable with a maximum of eight cables
AT80K - Monitoring up to 7,500’ (2500 m) equivalent
length per cable with a maximum of eight cables
Types of Cable
PAL-AT



AGW Gold Sensor cable for use in
containment piping, trenches, trays
and subfloors
AGT Gold Sensor cable for use
in subfloors and trays. More
sensitive than AGW
TFH Sensor cable for detecting
hydrocarbons and solvents while
ignoring water

Types of Probes
PAL-AT and LiquidWatch
PHL/PWS Solid state probes for
hydrocarbon and conductive liquids
 PSTV/PTHL/PFS Float switches for
high/low level
 PT10 (PAL-AT) Probe integrators and
PA-10 (LiquidWatch) Probe Adaptors for
dry contacts

LiquidWatch

LiquidWatch has two basic panels. The
LW64 is for use in normal classified
probe locations 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.
Applications





Raised Floors - Data Centers, ISPs, Clean Rooms
Telecommunication, Semiconductor, Office Bldgs
Pharmaceutical
Piping - Containment piping, single wall piping,
hydrocarbon piping, waste drains
Trenches and Trays - Under wet benches, piping
and equipment
Generators, Electrical Switch Gear and
Transformers for hydrocarbon leakage or water
seepage
What ever needs liquid leakage detection that a
probe or sensor cable can be used
Palcom Software
PAL-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 for
each system for location of leaks,
breaks, shorts or probe activation's.
