general information:
The flow meter DF9648 is used in food technology, chemical and pharmaceutical industry and water technology. In connection with any type of pulse-giving flow sensor the current flow rate can be measured and indicated. In addition the device can also acquire the total flow (totalizator). The dosage of quantity may be realized by using the alarm outputs. The optional pulse output allows an external processing of the flow quantity.

- measuring unit programmable
- totalizators programmable
- pulse output for external evaluation
- max. 4 alarm outputs, relay or transistor
- galvanically isolated analog output 0/4 mA to 20 mA, 0/2 V to 10 V
