Batch Controllers and Stroke Counters

By using the pulse of air that discharges when the pump stroke ends, we can monitor the strokes the pump has made, and use this function to do a variety of things eg.

1) Despatch a set volume of liquid ie (Chamber Volume) x (Number of Strokes) = Dispensed Volume.,

2) Monitor Diaphragm Life to regulate maintenance plans

3) Monitor Performance of Different Diaphragm Materials under different conditions eg Chemical Attack, Temperature Degradation, or Mechanical Wear.

4) Automate mixes eg, Control Primary colours in a mixing plant to make infinately variable blends depending on ratios.

The All Pneumatic Batch Controller and Stroke Counter

Of the many Batch Counters on the Market today most rely on the presence of Electricity to function, As AODD Pumps are designed to work on Compressed Air alone, it made sense to design a Batch Controller / Stroke Counter that was all pneumatic aswell.Features

  • The design allows 'auto reset' of the counter or 'manual reset' for applications where the number of strokes is variable.
  • It also incorporates a totaliser, ideal for planned maintenance or just monitoring Diaphragm Life Spans
  • Manual Start Button and Emergency Stop
  • If the air supply is intermittent the pump can continue it's countdown upon re-pressing the start button.
  • Intrinsically safe, for those environments where electricity is unwanted.
  • Portable, can be mounted on a trolley with the pump for ease of use.
  • Fully adjustable from 1 to 99999 strokes.
  • Repeatability of performance, even with fluctauating air pressures

Electric Batch Control Systems

Most manufacturers offer a Form of batch controller / stroke counter, we feature here the Warren-Rupp Model. RuppTech TM

  • Turns your diaphragm pump into an accurate, controllable pump system
  • Interfaceable, user-friendly components for existing and new pumps, and process control systems
  • Eliminates troublesome and expensive flow-sensing devices.
  • Runs pre-programmed batches and formulas with 1% - 3% accuracy.
  • Tracks volume or value of pumped product for loss prevention and cost analysis.
  • Monitors pump strokes to determine preventative maintenance schedules.
  • Counts positive, electrical signals.
  • More accurate than air exhaust-activated controls.
