Flow switch
Flow switch
(OP)
I have a flow switch which is used as a fan start permissive it is on the outlet of a lube oil unit. If the flow of oil is greater than 40 l/min then the start can continue. If for some reason the flow goes below 40 l/min then an electric pump needs to be started to bring the flow up. Am I right in thinking that this is only one switch point on 40 l/min falling? It's driving me crazy.
Thanks

The deadband dpc referred to should be listed in the datasheet for your flow switch.

Less, more expensive and also too narrow a deadband may result in "chattering" in many applications.

Whatever the deadband may be, the odds are very good that the designer has chosen a switch with a deadband appropriate for the application.

Two identical models can have different deadbands within the spec'd range.
