FS-380P Series

Product catalog summary

Installation Instructions:
All NPT threads should be installed using a suitable thread sealant like Teflon tape or Permatex 'No more Leaks'. Ensure the sealant does not enter the unit during installation. It is recommended to have ten diameters of straight run piping both upstream and downstream of the flow sensor.

Mounting Positions:
The FS-380P Flow Switches can be mounted in various positions. Flow settings are based on a vertical position (inlet port down) using water at +70°F on increasing flow. Different mounting orientations may cause variations in set point actuation.

Wiring and Electrical Specifications:
The switch is normally open with a contact rating of 10W. It supports a maximum switching voltage of 200V (DC or AC Peak) and a maximum switching and carry current of 0.4A. The breakdown voltage is 230 VDC minimum.

Specifications:

Wetted Materials: Housing and End Fitting are made of Hydrolytically Stable Glass Reinforced Polypropylene, Piston is PPS Composite, Spring is 316 Stainless Steel, and O-Ring is Fluorocarbon.
Operating Conditions: Maximum operating pressure is 200 PSI at 70°F and 100 PSI at 212°F. Operating temperature ranges from -20°F to +212°F (100°C). Required filtration is 100 Micron or better.
Set Point Accuracy: ±20% maximum with a set point differential of 20% maximum.
Switch Type: SPST, 10 VA.
Connections: 3/8” NPT Male or Quick Connect with No. 24 AWG, 24” to 26” Polymeric Leads.

Compliance and Safety:
The FS-380P is UL and CSA approved. It must be installed and maintained according to the National Electrical Code and applicable Gems product instructions. For hazardous applications, use appropriate explosion-proof enclosures or intrinsically safe interfaces. Adhere to pressure and temperature limitations to avoid system failures.

Return Policy:
Returns are accepted on stock items within 30 days from the order date. Contact the Returns Department for a Return Authorization (RA) number. Goods must be returned freight prepaid in the original container with the original packing slip. C.O.D. returns are not accepted, and restocking charges may apply.

Important Considerations:

Ensure material compatibility with the media for optimal product life and operation.
NSF-approved sensors are suitable for potable water applications.
Switch contact life expectancy varies with application; contact Gems for life cycle testing if needed.
Minimize shock and vibration to ensure sensor longevity.
Field repairs are not recommended for these sensors.

Dimensions:
The product is suitable for Class I and Class II applications per standard EN60730. Class I compliance requires grounding for metal-bodied units, while plastic-bodied units in contact with conductive media require effective earthing. For Class III compliance, a supply at safety extra-low voltage (SELV) is necessary.
