Product Usage Instructions

Connections

The XACT COUNT cycle counter is equipped with 1 NPT female connections at the valve inlet and valve outlet. These end connections may be converted to a different connection type or size by using pipe bushings or other pipe fittings. However, it’s important to note that reducing the flow path by decreasing the fitting size may result in inaccurate count results.

Installation and Flow Direction
The XACT COUNT cycle counter incorporates a check valve in its design to limit backflow of fluid through the counter. Therefore, fluid can only flow through the counter in one direction. To ensure proper installation, orient the unit according to the arrow laser engraved onto the exterior of the counter. The arrow points from the valve inlet towards the valve outlet.

If the counter orientation is reversed (i.e., if the fluid source is connected to the discharge side of the counter), the pump will not function and the counter will not record pump strokes.

Important Notes

1. Ensure Proper Flow Direction: If the counter orientation is reversed (i.e., if the fluid source is connected to the discharge side of the counter), the pump will not function and the counter will not record pump strokes. This can lead to system failure.
2. Fluid may be hot: Fluids transported through the counter may be hot. Exercise caution and allow the unit to cool before disassembly or maintenance to avoid burns on contact.

INTENTED USE APPLICATIONS

QED Environmental Systems Xact Count™ cycle counter is a liquid pulse detecting unit that 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.

The Xact Count requires no adjustment.
The Xact Count cycle counter is designed to count fluid cycles in pumping applications. While designed specifically for AP4 landfill remediation pumps, this counter is capable of monitoring flow on many different applications that meet the cycle parameters below. Please contact QED for application assistance.

ENVIRONMENTAL PARAMETERS

For accurate counting, the following parameters must be met:

Submergence Limits:

Air Pressure: Supply air pressure > 10psi over total developed head required

WARNING

PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not limited to:

• Protective eyewear, and hearing protection
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer

INSTALLATION AND OPERATION

CONNECTIONS

The Xact Count cycle counter is equipped with 1” NPT female connections at the valve inlet and valve outlet. These end connetions may be converted to a different connection type or size by use of pipe bushings or other pipe fittings. However, reduction of the flow path by decreasing the fitting size may result in inaccurate count results.

INSTALLATION AND FLOW DIRECTION

The Xact Count cycle counter incorporates a check valve in its design to limit backflow of fluid through the counter. As such, fluid can only flow through the counter in one direction, necessitating that the unit be oriented accordingly. The valve body exhibits an arrow laser engraved onto the exterior of the counter, showing the flow direction. The arrow points from the valve inlet towards the valve outlet.
If the counter orientation is reversed (i.e., if fluid source is connected to the discharge side of the counter), the pump will not function and the counter will not record pump strokes.

DISCHARGE CYCLE COUNTER OPERATION

When a pneumatically operated pump such as the QED AutoPump® has filled, it triggers itself “On”. This allows air to flow to the pump until a certain volume of fluid has discharged. The air ingress and fluid discharge stop, the pump refills, then the cycle repeats. An Xact Count mounted between pump and discharge reservoir/force main senses liquid flow from the pump. In a piston- like action, the internally located poppet moves forward (in the direction of liquid flow) during the “On” pulse and returns to a seated position in the “Off” period. Once seated, the poppet prevents back flow from the force main to the pump. The digital display senses the completion of the “to-and-from” movement of the poppet and records the cycle, increasing the number one digit that is shown in the clear plastic display. This process repeats itself for each pump cycle. DIGITAL DISPLAY

The digital display has the following features:

• A six digit counter that counters from 0-999999 before resetting.
• A clear viewing lens that is water and impact resistant.

MATERIAL CONSTRUCTION
The Xact Count is constructed from the following materials:

• Engineering Plastics (Display)
• Viton (O-Ring)
• Neodymium (Magnets)
• Stainless Steel (All other components)
