Plating
Line: EchoPod was installed in multiple rinse
tanks for a leading manufacturer of the aircraft industry. Each
sensor was quickly retrofitted into the existing PLC system to
provide alarm and refill control of the tanks. Due to the limited
space and the corrosiveness of the environment, EchoPod was a
perfect fit.
Waste
Sump: EchoPod was
installed on a wastewater tank catching a mixture of zinc and
wastewater. The sensor monitored 4 levels including a high alarm.
Due to heavy turbulence in the tank, a standpipe was used to dampen
the wave motion allowing for a tight tolerance between activation
points. Due to the coating nature of the liquid, the customer
preferred a non-contact solution to reduce maintenance time required
to rinse/clean contact devices. EchoPod provided the solution.
Diesel Fuel
Tanks: EchoPod was installed on
diesel fuel tanks for a yacht. The 4-20 mA output provided the level
of the fuel in each of the 4 tanks and were all run to a local
display in the wheelhouse to track the usage of fuel (in gallons) as
the ship cruised. Due to the limited space for installation, EchoPod
was the perfect choice.
Chemical Feed
Tanks: EchoPod was installed in a chemical feed
system to indicate re-order levels for the chemical. The relays
outputs provided a local high-level alarm to prevent overflow as
well as a low level alarm to indicate a re-order level. The unit was
directly wired into a controller that enabled the supplier to record
an overflow as well as send an email notification when it was time
to reorder. The small size and non-contact controlling made EchoPod
the best solution.
Water
Chillers: EchoPod was installed in a Water
Chiller used for the semi-conductor industry. The level of coolant
is very critical for the effectiveness of a chiller. The sensor was
wired directly to a local controller to provide three relay output
to indicate the coolant storage tank was empty, full and too full.
Because of the nature of chillers, temperature swings are always
present. EchoPod provided a solution that met the environment of the
chiller, the limited space available and direct connection to the
existing controller.
Electroplating Final Rinse
Tank: EchoPod was
installed in the final rinse tank of a machine that electroplates
copper wire at high speeds. Previous installations of reed switches
and magnetic floats had proven to be unreliable which resulted in
unscheduled shut down. EchoPod was selected because of the compact
size, programmable range and resistance to the effects of the acidic
environment. The 4-20ma output of the sensor is fed to the PLC,
which in turn controls the level in the tank as well as machine shut
down in the event of loss of the rinse water. Installation of the
EchoPod was virtually Plug and Play. The sensor directly replaced
the original equipment with no hardware or software changes
required.
Process Water Cooling
System: EchoPod was installed in tandem with an
EchoSonic sensor. The sensor is used as the backup for level
indication with the 4-20 mA output as well as a low level alarm,
which will shut off the main pump and activate an alarm. What makes
this application critical is that the cooling tower has such a
capacity for a volume of water that the pump would drain the tank in
less than 1 minute. EchoPod was wired directly to an existing PLC
that does all of the controlling for this system.
Steel Tube
Processing: EchoPod was installed in a shallow,
but large capacity sump that contains the waste from harsh acid bath
washes. The sensor was mounted on the top of the sump through a
stilling well that extends 4 feet down to the bottom. EchoPod
provided level indication back to a local display as well as control
of two pumps to maintain the process.
Bulk Transfer Pump: EchoPod was installed in 200
liter day tank and was used to control a bulk transfer pump as well
as a high and low alarm for a local municipality. The sensor was
connected to a local controller that activated the pumps and/or
alarms based upon the switch inputs from EchoPod. The tank contained
sodium hypochlorite, which was used for chemical feed. The compact
size and flexibility of control features made EchoPod the right
solution. |
