Figure 10: Latching switches
The AC and DC powered Flow-Alert modules consist of a relay circuit housed in a sealed
plastic enclosure� The modules have a normally open, dry relay contact that can be used to
directly control alarms, warning lights, relays or interface to a PLC� The relay is latched on as
the magnet inside the flow meter passes by the module, and remains latched on until the
magnet passes in the other direction, or power is interrupted� See
Figure 10
� The setpoint is
adjustable from 0…100% of full scale� Flow meters can be equipped with one latching limit
switch, either AC or DC�
