Aquarian 1000Plus

untitled-5The Aquarian 1000Plus represents the standard in electronic level detection. Based on the widely accepted conductivity probe technology, it was specifically designed to meet industry’s growing needs and demand for a reliable, cost effective and versatile means of sensing water levels in a variety of applications.

Equipped with one to four probes which can be mounted directly to pressure vessels or factory mounted in a column, the Aquarian 1000Plus measures the difference in resistance between high purity water and steam. The insulated probe and the pressure vessel, in which it is mounted, form a resistivity cell. Coupled with a reference resistor, the cell forms a resistor divider network. By passing a square wave dc voltage through the network, and processing the resulting signal, a distinction between steam and water is made, even in water conductivities as low as 0.5 micromho.

To provide maximum system reliability and diagnostics, redundant power supplies were incorporated to maintain system operation while alarming operators of system service requirements.

In addition to level indication, the Aquarian 1000Plus provides relays for each probe, enabling it to serve as a system trip, alarm or on-off control device. The system is completely field configurable to provide maximum versatility.
