    • not isolated (battery powered) - for standard internal battery version • galvanically isolated (mains powered) - for KROHNE FlexPower version The WATERFLUX 3070 flow converter and FlexPower with Modbus has a RS485 interface to communicate with an external device (PC or other suitable computer system) using the Modbus protocol.

  • Page 79: Legal Metrology

    The measuring range of the water meter is determined by Q3 (nominal flow rate) and R (ratio). The WATERFLUX 3070 meets the requirements for water meters of accuracy class 1 and 2. • For accuracy class 1, the maximum permissible error for water meters is ±1% for the upper flow rate zone and ±3% for the lower flow rate zones.
