This first of a kind flow-captor
is two sensors in one. It not only monitors the flow rate
but also the temperature of the flowing medium and provides
a solid-state switch if flow is lost or temperature is exceeded.
The CoolGuard is solid state with no moving parts and is the
ideal replacement for old-fashioned mechanical flow switches.
It won't foul, stick, wear out, or be damaged by excessive
flow rates. It can be mounted horizontally or vertically with
no effect on the switching point. It has Normally Open "fail
safe" switching logic, unlike mechanical switches that
often fail indicating flow is ok when no flow exists. CoolGuard
is simple to install and is factory pre-set so it requires
no calibration or adjustment.
Priced right for the OEM as well as the small quantity user,
the CoolGuard is the long awaited solution to low cost , solid
state flow and temperature monitoring.
The flow-captor CooLGuard utilizes the weber pioneered calorimetric
principle and the unique "therm-o-sense" circuitry
that monitors the cooling effect and temperature of the cooling
media instead of just the flow.
When the cooling power of your system goes down, the temperature
goes up, or flow is lost.CooLGuard comes into action.you can
depend on it!
CooLGuard is especially designed, for all types of cooling
systems, as a reliable alternative to failure prone mechanical
flow switches.
Evolution of the CooLGuard
Every Cooling System relies on a consistant flow of coolant
to control the temperature of a process. The cooling effect
of the medium is dependant upon the flow rate and the medium
temperature. Most cooling schemes employ a simple mechanical
flow switch to ensure that a minimum flow of coolant is occurring
and a temperature monitor to alarm if the process overheats.
Typical Cooling System Problems
The problems with mechanical flow switches are their inherent
moving parts, which are subject to wear and sticking. The
typical vane type switch will always fail in the worst way.open,
which will indicate that flow is occurring even when it is
not. The mechanical flow switch also fails to take into account
another important aspect of the cooling process... If the
coolant temperature increases, a higher flow rate is required
to maintain the same process temperature.
Accordingly, a higher "flow setpoint alarm" is
required. Conversely, if the coolant temperature decreases,
a lower flow rate is needed to maintain the process temperature
and a lower "flow setpoint alarm" is needed. The
mechanical flow switch can not adjust to this change and may
not alarm in time at higher medium temperatures and may alarm
too soon at lower medium temperatures. In addition, mechanical
switches do not monitor the process temperature for over-
temperature conditions.
Now the CooLGuard flow-captor, with its unique "therm-o-sense"
circuitry, has solved both of these shortcomings. The CooLGuard
continually samples the temperature of the coolant and adjusts
the low flow setpoint automatically, providing a solid state
switch should the coolant flow rate fall below the setpoint
value.
In addition, the CooLGuard will provide an alarm output should
the coolant temperature rise above acceptable levels. You
have Double Protection with the CoolGuard.
