  • The Contrec 505-BC03 application is a Dual Stage Batch Controller for reliable measurement of preset quantities using a Mass Frequency Input. Used as a single or dual stage contoller it is suitable for fast batch applications.
  • It provides the operator with clear local readout and can be controlled via communications in more automated systems.
  • There is quick access to commonly used preset values directly from the front panel if access has been authorized.
  • Automatic overrun compensation caters for system delays such as valve closure for precise volumes.
  • Contrec 505 is compatible with a wide range of flowmeter frequency outputs, including millivolt signals, reed switches, Namur proximity switches and pulse trains via its smart front-panel program selection.


  • The total and flowrate are derived from accurately measured frequency and the number of received pulses.

mass = pulses / k-factor

mass flow = frequency / k-factor

  • Automatic overrun compensation calculates the new valve closure point to ensure correct delivery by averaging the overrun amount from the last three complete batches.
  • The overrun compensation value is valid for a new preset value provided the stored overrun is less than 20% of the new preset.
