Product Overview
The INCON TS-1001 / 2001 /504 / 508 / 750 Tank Sentinel ® consoles are complete leak detection
and inventory monitoring systems. The TS-750 / 1001 / 2001 models run in-tank leak tests
with exceptionally high accuracy. The TS-504 / 508 models are designed for monitoring and
controlling liquid levels in aboveground storage tanks.
The tests meet or exceed all current EPA standards.
A broad range of liquid products can be leak-
tested and inventory-monitored (or gauged)
simultaneously in many storage tanks.
Inventory monitoring is done with a very
special sensor called a Liquid Level Probe
that has a product float. With petroleum
products, water floats are used. When a
programmed limit is reached, then a tank-
related alarm will be produced at the console
for that specific tank.
Additionally, these consoles can monitor a wide variety of leak detection sensors which
are installed within – the walls of double-walled tanks (DW or DWTs), containment sumps,
dispenser pans, and groundwater or vapor monitoring wells near USTs. Leak detection
sensors produce alarms when exposed to liquids such as product. Some produce alarms
at various liquid levels, or when water is absent (as with a ground water monitoring well
sensors), or when they are exposed to hydrocarbon vapors (as with a vapor sensor).
Of the many types of leak detection sensors that are available from INCON, these can be
divided into two basic types — one is called a Standard Sensor and the other is called a
BriteSensor™.
BriteSensors™ are sensors with built-in intelligence. Within them is a small computer that
uses digital data to communicate with the system console. The data sent identifies the
sensor-type and status of each alarm that it can detect. Some BriteSensors can tell the
difference (discriminate) between water and a hydrocarbon (product) and will produce
different alarm-codes for each of these.
On the other hand, Standard Sensors do not use digital data. Instead, the Standard Sensor
operates like an ON–OFF switch that’s
closed when no liquid is present – or – open when
a liquid is detected. When a liquid is detected, the loss of signal produces a standard
sensor alarm at the console.
