Fossil Power Systems Aquarian electronic water-level instrument. The supplied record describes the Aquarian sensing principle but does not identify the exact model or which assembly/components are included.Source series descriptionAquarian electronic level products, were specifically designed to meet the industry’s growing needs & demand for a reliable, cost effective and versatile means of sensing water levels in a variety of high and low pressure applications. By passing a square wave ±5VDC 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.The ±5VDC square-wave statement describes the sensing network, not a verified power-supply input for this stock. The 0.5 micromho conductivity figure and high/low-pressure wording are series-level claims, not confirmed operating limits or boiler-safety approval for the item supplied.Confirm the nameplate/model, controller/probe contents, electrical supply, process pressure/temperature limits and approved application before ordering or installation. Do not use this description as wiring instructions or proof of suitability for a steam/boiler protection function.
