Aquarian 3000Classic

The Aquarian 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.

Key Features:
• Solid state electronics and two colour display
• Up to three remote displays
• Up to 24 conductivity probes
• Three way adjustment for water conductivity
• Redundant power supplies
• Level fault monitoring
• Local/remote fault indication
• Field configurable
