Hypo Trak General Description

Feeding and tracking sodium hypochlorite usage in municipal water treatment systems has presented a challenge for end users for many years.  First, sodium hypochlorite degrades over time which makes inventory control and usage documentation very tricky.  Secondly, when hypo degrades, it releases gas bubbles that can often get trapped in feed tubing and pumps causing inconsistent feed and in some cases a “vapor lock” of the pump itself.  Lastly, as sodium hypochlorite loses strength, it forms byproducts called chlorates.  Chlorates are known to impair thyroid function, and therefore regulatory officials are beginning to regulate how much chlorate can be in the water supply, and more specifically, how much chlorate can be contributed to the water supply from the source sodium hypochlorite. 

By integrating specialized software with our simple weighing / level display, the Hypo Trak can easily monitor the following:  

1) an inconsistent or no feed rate condition via loss in weight (or level) to warn of a vapor locked pump,

2) integrated timers that track how old the hypo is to warn of an excessive chlorate condition,

3) degradation curves that allow you to track your hypo strength over time as it loses strength and

4) conversions that allow you to view & track your hypo in terms of 100% pure chlorine gas to simplify inventory control, PPM calculations, and usage documentation.
