Flow converters Floukor DRC-B1, DRC-B2, DRC-B3, etc.

The DRC converter is available in four versions:

• DRC-B1, DRC-VM has a pulse output. During the time between the two pulses, a given volume of liquid is pumped through the pipeline. In the future, this volume is referred to as the impulse price. In addition, the DRC-B1 is equipped with an indicator of accumulated volume, instantaneous consumption and operating time.

• DRC-B2 has only a pulse output.

• DRK-V3 has a pulse output, an indicator of accumulated volume, consumption and operating time.
