According to QED, personnel using most current cycle counters on the market 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 no real way to know if the fluid inlet check is stuck open or if fluid is being pumped to the surface. The Xact Count cycle counter solves these issues by monitoring the water discharge flow rather than monitoring pneumatic airflow as a proxy.
While designed 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 the number of times a pump cycles. An Xact Count cycle counter consists of a valve housing, an internally located 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 of wear-resistant stainless steel. The internals of the valve have been optimised for maximum debris to pass and for minimal fluid disruption. The design eliminates the need for an airline counter and thus minimises airline restrictions.
The Xact Count is said to provide high accuracy in conditions where pump submergence is less than or equal to 2/3 of pump depth (AP4).
