Outputs
This screen allows to program the three outputs of the instrument: Relay 1, Relay 2 and
analog output (4-20 mA).
6.5.1
Relay 1 and relay 2
When selecting one of these screens we have access to program the flow rate at which the
relays will change its state and to the level of hysteresis. By level of hysteresis we understand
the difference between connection and disconnection of the output. To avoid that an alarm
output is continuously moving from activate to deactivate state, we must program the points
of connection and disconnection.
Example
If the activation point is programmed to 100 m
to 90 m

value of 100 m

If we program an activation point of 90 m
flow rate is zero the output will be on. When the flow rate reaches a value of 100 m
output will go off and it will not go on until the flow rate falls below 90 m

Analog output
The flow rate corresponding to 4 mA and 20 mA, and the calibration for these two values
can be programmed.
