Can a flow switch handle more flow than the flow set point?
A flow switch can typically handle a greater flow rate than its flow setting. Many flow switches are set 4 times less than the actual operating flow rate. As flow rate increases, pressure drop also increases, eventually causing a restriction of flow.
Can a flow switch be mounted at an angle?
Yes, piston and shuttle type switches utilizes a small, strong spring, that is not bothered by the mounting attitude of the flow switch and will perform at any orientation. The exception is our FS-400P, which is spring less.
Can a flow switch be cleaned?
Yes. The design facilitates cleaning by flushing out the flow switch with clean water. Some flow switches have removable parts for a more thorough cleaning.
Are flow switches set on the rise or the fall?
Typically, catalog units are set on the rise. Rising set points are most commonly used in coolant loops to insure proper flow. Switches can be calibrated on the fall when required.
