FS-200 Flow Switches for Safety Showers and Eye Wash Stations
May 20, 2021
Most Chemical and Industrial plants will have several safety showers and eye wash stations for emergency flushing of harmful chemicals or gases. Should an accident occur when a worker is alone, they may be able to use the shower or eye wash but be unable to summon help. By installing a flow switch in the water line to the flush station, the switch contacts will close when the flow increases, and the signal from the reed switch can energize a warning light and sound a bell to alert supervisory personnel.
Challenge
Having a reliable flow switch that can handle the high flow of a safety shower or eye wash station and also provide minimal back pressure.
Solution
FS-200 Series Flow Switch
Gems FS-200 Series in-line flow switch is a rugged sensor constructed of either 316 SS or Bronze. Its shuttle-based design allows for an efficient flow path, assuring low line pressure drop. This is crucial for a high-flow safety shower or eye wash station, as the proper flow is needed to wash away any hazardous material quickly.
With port sizes ranging from ¾” NPT to 2” NPT, it can handle flow rates as low as ½ GPM or as high as 50 GPM. Additionally, once the setpoint is achieved, it exhibits excellent repeatability of 1%. This repeatability ensures that the FS-200 flow switch will indicate the emergency station has been activated, allowing emergency personnel to quickly aid the injured worker.
If your flow rates can vary and you’d like to have the ability to adjust your setpoint, the FS-200 is also available in three adjustment ranges.
All these features ensure the FS-200 is an excellent fit for use in safety showers and eye wash stations, helping to keep people safe.
