7.5.1.1 Alarm; 7.5.1.2 Empty Pipe; Negative Flow; Pulse Output - Tecfluid FLOMAT Series Instruction Manual

7.5.1.1 Alarm

If Alarm is selected, we have access to program the flow rate at which the relays will change
its status and to the level of hysteresis. By level of hysteresis we understand the difference
between activation and deactivation of the output. To avoid that an alarm output is
continuously moving from activate to deactivate status, we must program the points of
connection and disconnection.
Example
If the activation point is programmed to 100 m
to 90 m 3 /h, when the flow rate is zero the output will be deactivated. When the flow rate
reaches a value of 100 m
h.
If we program an activation point of 90 m
flow rate is zero the output will be activated. When the flow rate reaches a value of 100 m
the output will be deactivated until the flow rate falls below 90 m

7.5.1.2 Empty pipe

In this case, the relay will change its status when the flowmeter detects empty pipe.
7.5.1.3 Negative flow
The relay will change its status when the flow rate changes its sign.
7.5.2

Pulse output

This output allows to connect the converter to a PLC or remote totalizer. The number of
pulses per unit of volume can be programmed. The following parameters can be selected.
