Contrec 505-BC01 Frequency Input Batch Controller Product Highlights
- Contrec 505-BC01 application is a Dual Stage Batch Controller for reliable measurement of preset quantities with Volumetric Frequency as the input signal.
- The 505-BC01 as a single or dual stage controller hence it is suitable for fast batch applications.
- It provides the operator with clear local readout and also can be controlled via communications in more automated systems. Hence 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 flow meter frequency outputs, including millivolt signals, reed switches, Namur proximity switches also pulse trains via its smart front-panel program selection.
- The accurately measured frequency and the number of received pulses are to derive the total and flow rate.
volume = pulses / k-factor
volume 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 automatic overrun compensation value is valid for a new preset value while last overrun is less than 20% of the new preset.
