Proline Cubemass 300 Modbus RS485 Description of device parameters

Flow values can aggregate in the buffer in the event of prolonged and unwanted fluid
reverse flow. However, these flows are not taken into consideration by the current output
configuration, i.e. the reverse flow is not compensated.
If this option is set, the measuring device does not attenuate the flow signal. The flow
signal is not attenuated.
Examples of how the current output behaves
Example 1
Defined measuring range: lower range value and upper range value with the same sign

With Forward flow option
The current output signal is proportional to the process variable assigned. The flow
components outside the scaled measuring range are not taken into account for signal
output:.

With Forward/Reverse option
The current output signal is independent of the direction of flow.
