Unique design monitors water discharge rather than airflow, eliminating all doubt about whether pumps are working correctly

Dexter, MI - Q.E.D. Environmental Systems, Inc., a leading manufacturer of innovative
environmental products and subsidiary of Graco Inc. (NYSE: GGG), highlights the Xact Count TM
pneumatic pump cycle counter for reliably monitoring pump performance, maintenance cycles and
estimating liquid volumes being pumped. The unique design monitors water discharge rather than airflow,eliminating all doubt about whether pumps are working correctly.

With most current cycle counters on the market, personnel can see the counter advancing and hear the
pump cycling and mistakenly assume that everything is functioning properly. It is not obvious, however,
whether the discharge line is disconnected, or the ball in the discharge check valve is missing. There is noreal way to know if the fluid inlet check is stuck open. or if fluid is actually being pumped to the surface.

The Xact Count cycle counter solves all these issues by directly monitoring the water discharge flow
rather than monitoring pneumatic airflow as a proxy.
While designed specifically for AP4 landfill remediation pumps, the Xact Count is capable of monitoring flow on many different applications. The liquid pulse detecting unit is placed in-line between a pump and its discharge reservoir or force main. It requires no external power source. A digital readout displays thenumber of times a pump cycles. An Xact Count cycle counter consists of a valve housing, an internallylocated and magnetically integrated poppet, and a digital display.

All wetted parts of the Xact Count are 316 stainless steel, and the seat and poppet are also constructed ofwear-resistant stainless steel. The internals of the valve have been optimized for maximum debris to passand for minimal fluid disruption. The design eliminates the need for an airline counter and thus minimizesairline restrictions. The Xact Count acts as a discharge check valve while also outperformingcompetitors at leakback prevention. It can be serviced and cleaned in minutes with minimal tools. TheXact Count provides high accuracy in conditions where pump submergence is less than or equal to 2/3 ofpump depth (AP4).
