3000Classic was the first Aquarian
developed to satisfy basic water level indication needs for boiler
drums, feedwater heaters and other liquid level applications.
The Aquarian system is comprised of three major components: the
water column with vacuum brazed water detection probes, the electronic
Detection and Verification (D&V) unit and the remote LED display.
The electronic system in the D&V unit
is connected to 5, 8, 10, 12 or more probes in the water column.
The Aquarian column is custom manufactured to provide the most
accurate indication for any application. The number of probes
selected by the customer are installed during the manufacturing
of the column and are spaced to indicate liquid level throughout
a desired operating range. Individual circuit boards are provided
for each probe level to provide versatility in selecting high/low
or other system alarm and trip level points. System fault indication
is provided by a relay which monitors the internal power supply
and the clock. A second relay activates if water is detected above
steam, a level fault. The electronic detection circuit for a probe
is mounted on a removable, on-line, circuit card.
A remote LED display panel, customized for
the number of probes, is standard. To provide maximum system reliability,
redundant power supplies are incorporated to maintain system operation
should one of the dual AC supplies fail.
