Gems Sensors FS-380 Series flow switches detect changes in flow rates and trigger specific actions or alarms when preset thresholds are exceeded or not met. They are effective in the manufacturing, chemical processing and HVAC industries for monitoring the flow of liquids or gases in pipelines.... For instance, in the manufacturing industry, flow switches can prevent damage to machinery by shutting it down when insufficient coolant flow is detected. In chemical processing, they can trigger emergency shutdowns in case of unexpected flow surges, avoiding potential disasters. In HVAC systems, Gems Sensors flow switches ensure that there is a proper circulation of coolant, preventing overheating or freezing.Read more

Yes, these piston switches use a small, strong spring that is unaffected by the mounting orientation and will work in any orientation.
You can clean them by flushing the flow switches with clean water.
Yes, as viscosity increases, set points decrease.
SPST (single pole single throw) switches are only wired in one direction, either normally open or normally closed. They ensure that these switches can only be wired in one direction.
A flow switch detects flow presence at a predetermined set point. A flow sensor is used to monitor the flow rate and inform the user of the flow rate.
Filtration prevents solid particle clogging. Although it is recommended, many applications do not use them. A general rule of thumb is that the lower the set point, the more susceptible the unit is to particles.
The pressure drop across the flow switch will not increase, but a pressure drop across the connector itself may occur. Each flow fitting has a pressure drop.
