Appendix F: Pump Cycle Counter

Introduction

QED Environmental Systems (QED) Pump Cycle Counters (PCC) are air pulse detecting units
that are placed in-line between a pump and its air supply. They require no external power
source. A digital readout displays the number of times a pump cycles. PCCs consist of a
magnet housing, an internally located magnet shuttle, and a digital display.
The position of the digital display is adjustable, allowing the counter to be used on many
different kinds of pumps and at various distances from the well. (See Figure 34)
The PCC can be used on at least 75 feet (23 m) of 3/8 inch (9.5mm) or
1/4 inch (6.4mm) air hose with air pressure supply 30% higher than the total developed head.
Performance of the PCC is dependent upon the air hose size and the length, the type of pump
and the system pressure. Air flow control valves can affect counter performance. Please
contact QED for application assistance.
