The Bubbler has an improved controller and pressure regulator that use a sophisticated system of sensors and valves to regulate the bubble rate and purge pressure. And to keep the sediment from settling around the orifice line, this Bubbler provides a purge feature to keep the pressure at a desired level. You can even start a manual purge, anytime, with the touch of a button. This system was made for those who don't have time to mess around at the site.
Designed to replace nitrogen gas purge bubbler systems, the WaterLOG® Bubbler (H-3553T) provides the highest purgre pressure in the industry (up to 90 PSI), while maintaining high accuracy thanks to its built-in NIST traceable pressure sensor. With programmable flow rates, a sleep current of 6mA, and an RS-485 connection, it is sure to be a favorite among your products.
