6.4 Flow rate

This screen displays a submenu to modify different aspects related to flow reading, such

as cut off, flow reversal, filtering and offset.

6.4.1 Cut off

A cut off flow rate can be programmed, that means, the flow rate below which the flow

rate indication will be zero. This can avoid reading errors in the lower zone of the scale.

The maximum allowed value for the cut off is the equivalent to a liquid velocity of 1 m/s.

6.4.2 Reverse flow rate

The CU100 is a bi-directional flowmeter. The flow rate changes its sign automatically

when the flow is reversed. If after the flowmeter has been installed it is necessary to

reverse the flow rate sign, in this screen it can be done selecting the option “REVERSAL–

Yes”.

6.4.3 Damping

The CU100 flowmeter has an adaptive filter (damping) to provide stable flow rate and

analog output readings in the presence of continuous flow rate fluctuations.

The configuration of this filter can be very useful in the cases where the flow rate readings

have some instability (due to air bubbles, solids in suspension, etc…).
