The GraviDos® stand-alone system also enables gravimetric dosing control even without a LabManager® automation system. The flow set point, the end weight and the dosing time can be pre-set both via the integrated keyboard and via a serial or analogue interface.
Both the suspended balance of the GraviDos® system and the 2/2-way solenoid valve required for the flow regulation are directly connected to the device.
The device is suitable for both continuous and batch dosing and supports automatic refilling.
An optional Ex isolator enables the operation of GraviDos® load cells in explosive areas. Intrinsically safe ignition protection class [EEx ia] IIC for zone 0, 1 or 2 is available as an option.
