The Aquarian 1000Plus
The Aquarian 1000Plus is configured with 1 to 4 independent probe channels, redundant power supplies, continuity, level fault monitoring and optional 4-20mA output. Each level relay output is rated at 5A which enables this system to serve as a trip, alarm or on-off control device.
Measuring the difference in resistance between high purity water and steam, the Aquarian 1000Plus is commonly used on Feedwater Heaters, Piping and Drains, Main Steam header drains, Hot/Cold Reheat drains and main boiler high/low alarm/trip.
The failure mode of this system makes the Aquarian 1000Plus very popular on Turbine Drain Systems for Turbine Water Induction Protection (TWIP).
