HewTech Electronics LLC developed an automatic 2 tank continuous supply for Cryogenic Liquid source applications. This instrument will monitor a supply tank while maintaining an additional back-up vessel in a stand-by, or RESERVE mode.
When the initial tank is depleted, the system automatically switches to the second source tank for an uninterrupted continuous liquid supply. The “EMPTY” tank can then be refilled and placed in the “RESERVE” mode, to be cycled back into the process upon depletion of the present source tank. The system provides visual and audible annunciation for RESERVE, IN-USE and EMPTY conditions. A 10 AMP SPDT remote alarm contact is also provided for connection to your alarm panel, PLC or DCS systems.
